Another Battery Storage Thread ...? Yes.

[hghost]

I have read many posts about the Lipo battery storage questions and I still wonder about them .

Fly Diver gives great info as well as many others across the board.

I read an article the other day online, I thought about it later but now can't seem to find the link.( another internet site)

In the article and the review one was doing, they did somethings I am not sure of and have a few questions concerning them.

Now I realize many store theirs in a Fridge, a good Idea I guess, but not something I really wish to do at all.
I see where some bought an apartment size Fridge to house their batteries in and there is a question.

The article mentioned placing them in zip-lock bags and storing them in the fridge some used the crisper drawer that most have.
They said they took them out and allowed them to come to room Temp and left them in the bag so they did not condensate .My experienced with anything that comes from the fridge in plastic and laying it out condensates...? I wonder about that, and that is question number 1......

Number 2 is they mentioned they would never leave a battery charged at room temperature for longer than 24 hours ? Now I , like most, charge batteries and leave them in case I get to fly, sometimes can be a spur of the moments notice, especially with weather conditions being so strange now days. And at times it may set in a metal container for a few days to a few weeks....I have noticed no loss in Power or shorter flight times by doing this.
The article poster said that Cooler temps cause the battery to discharge slower and that they only charged their batteries the night before flying and IF they never used them they discharged their battery and then set it for storage setting which is about 50% and placed them back in the Fridge and they did this all the time ?

Now I am no expert by any means on anything concerning batteries or anything for that matter, However, as I have worked around the automotive Industry most of my life, battery charging, discharging and extreme hot/cold fluctuations have in my experienced caused batteries to weaken and many fail ( of course a Auto Battery is not the same thing ) However...Most batteries operate the same way, the charging, discharging and the power it needs to charge or discharge etc etc...

SO...Why ?, if one charged and used, then discharged unused and or recharged half used on an almost daily basis and maybe many multiple times in a day and then going from Higher Temps to Lower Temps all the time, make a battery last longer ? Would that not weaken the battery and cause the battery to have a shorter life span ?

The poster noted that by doing it his way the battery life was longer and that batteries at room temps wore out faster and had shorter life expectancy in his testing ?

Now I am going to store my batteries in my metal container and I will have them set at a storage mode on my charger, ( as soon as I figure out how )..But until I know that I will not be able to fly at all..I will not do that until then. And I will store them in an out building in the winter where it is far cooler than my house, and safer .

Anyone else hear or have any tests to show Room Temp is a bad thing for Lipo batteries ? OR if leaving them charged for a period of time a few days or a week or so makes them weaker and shorter life span ?

Many have stored theirs fully charged during winter months with no affects or seemingly no affects...is that True or just Lucky ?

Mentioning batteries and I am sorry this post is so long, I just like real info that can be trusted. I also have hard to understanding things so I ask many things sometimes more than once.
I also have Nimh batteries I have charged and stored all winter and many work fine the next year and a couple seems to not last as long as they once did, but they get allot of use....so reason why i ask about the Lipo's ( I have never used Lipo's until this year)

The Poster of the article noted that the cold caused the Lipo to discharge slower and why so many have issues in winter use...so if the battery is affected by the cold, why would not Cold storage also have an ill affect ? I understand the slower discharge while in storage, but I still wonder about ill effects cold will have then going to charge heat and discharge heat and use heat back to cold, versus normal room temperatures to normal use ? Not extremes just normal Room Temps versus cold temps ?

Any and all info and suggestions or simple thoughts would be appreciated

Trying to teach this old dog new tricks is a challenge and a far greater one to get it in my head...a chore indeed, but that is what I am trying to do is learn.

Batteries can get expensive, want to keep them as long as possible without having to buy some every year or two...if possible.

Plus the Fridge storage sounds a little dangerous should there be a mishap and can be costly if it does, a new Fridge can be a very High expense if something went wrong..not counting the food or whatever my occur....Keeping it in a metal container in an old out building sounds easier and safer in my opinion ( that is just my opinion ) The metal container would contain the flame for the most part, zip-lock bags I think would only fuel the flame as well as whatever else is in the fridge ?

Saw a few videos about the storage in containers, ammo boxes etc etc....some are like Bombs where as some are perfect ( an old cash box for example )So...that's my Post..Hope many can give some insight and personal experiences with these Lipo's.

Thank you all in advance.

You've done a bit of reading. This is an area you can go OCD on if you want, or mostly ignore it like most people. Either way....you end up with issues to deal with.
You have to figure out your own path, generally factoring in convenience, safety, and cost. How these fall to different people is different.

This guy knows more than you are I ever will. Proper (?) LiPoly management
www.rcgroups.com/forums/showpost.php?p=16421261&postcount=1

Lead batteries are NOT Lipos. Don't even try to compare them in ANY way. NiXX is pretty different also. There are some noticeable differences between the lithium chemistry.
Lipos degrade with amount of charge, charge duration, and temperature. High performance (High-C) lipos seem to suffer more from this. The Cub, and a LOT of planes, are pretty low performance. A degraded battery does not affect them much. IMO people that keep them charged all the time and claim no difference fall into this category. As soon as you start flying battery eating Helis, EDF, jets, or other 'battery eating monsters' you find out. I'm ignoring ignorance, abuse, and stupidity for this discussion which is a MUCH bigger problem.


A fully charged lipo is a 'bomb', but so is a gallon of gasoline. You need to treat them with some reasonable precautions.
A half charged lipo is much less volatile. A cold half charged lipo is almost inert. You don't want them in a fridge in the house? Don't keep them there.
You want them charged and ready on a moments notice? Then expect them to be degraded faster and keep them in a safe place.
The vast majority of lipo 'accidents' are charging errors/problems or crash damage. A lipos simply sitting there has a minimal probability of igniting.

If you take a question like that to RCGroups or Wattflyer you'll get about 20+ opinions and many of them will agree and some will not agree. Some may know what they are talking about. Others will know less than you. Ignorance does not stop people from giving dumb advice. Ultimately you make up your own mind since there is not an absolutely correct answer. There are some really bad things to do, some good things to do, and some choices to make to suit your circumstances.

[renard80]

If you are a casual, low-use pilot of a park flyer like the Super Cub, I believe it is easy to become unnecessarily anxious and baffled by science.

FWIW, here is my experience. It is emphatically no substitute for the wise advice of flydiver and others with infinitely more technical know-how than I possess.

Like you and many others, I cannot pre-plan my flying. Weather is generally unpredictable, the weather forecasts unreliable, domestic requirements ditto. So, when the conditions are suddenly right, I want to grab my plane etc and head for the field - now. No time to charge up the batteries!

This entails re-charging my batteries immediately after flying and storing them fully charged. I still use the stock charger that came with the plane. The charged batteries go into 'LiPo Safe' bags, which in turn go into my aluminium 'flying box' with my Tx and other bits and pieces. The box is kept in my study until needed.

I have done this for more than three years without incident and without noticing any appreciable diminution in battery duration or performance. As flydiver infers, perhaps this is partly due to my flying only a low demand aircraft, the HZ Super Cub.

I handle my LiPos carefully. Should they show damage, 'puffing' etc, they would be discarded.

OK, my practice may be wrong. But it works for me in my circumstances, and I do not think it is dangerous.

I acknowledge that I may be shortening the life of my batteries. But, as flydiver often remarks, some of us are content to trade cost for convenience. As he also says: your batteries, your money, your choice.

Hope this is useful.

[flydiver]

I maybe should have added complexity as one of the issues associated with charging. The whole field gives people grief at first. Why are there all those stupid connectors, why don't chargers simply plug into the wall, why do you need a power supply, what's with this balance stuff, LVC, over charge, over discharge, etc.
Then you get a better charger because everyone says you should and now you have to figure out how to operate the #^#$% thing. The directions are worthless.
All of those and more are real and common issues. Lipos intimidated me. I was loathe to buy into lipos for over 6 months but back then NiXX was still a viable option and that's how the Cub and most RTF planes came. Now folks don't know squat about NiXX. The world changes.....

BTW Renard, if you ever do get a 'better' charger folks like you should take a good look at the FMA Cellpro 4S. I have 2. Very easy to operate and very safe. You can use them at 3C to shorten charging time with no problem.

[toff]

Just my tuppence worth.... with the SC or any other 'slow' fly plane, the charging of lipos can be a relatively easy and straightforward affair. However, having flown 4s EDF jets, charging and balancing becomes paramount. I can honestly say that having the motor die after a very short speed run is no fun at all, as jets don't glide very well.... Lesson learned, and 4s lipos are expensive, in comparison the 3s. It all comes down to what you want out of this hobby.

[hghost]

Thanks Guys for your input.......Not going to try and over analyze it...but trying to just get as much info as possible

And with crazy weather conditions, reading up on this stuff seems to have become the norm for me.

Now If I could just understand the Manual that came with this charger ( Thunder AC 6 )...

seems maybe by reading the article fly, cheaper batteries do not always mean savings in the long run...and having a great charger is a good investment..........there is a difference in Good batteries and cheap batteries as well as Good and Cheap Chargers.


Thanks to all again

[flydiver]

If you are into mega reading this thread on the Accucell-6 will give you some diversion (or boredom) for bad weather times. It also lets you see how often people have the same question over and over for these chargers.
www.rcgroups.com/forums/showthread.php?t=886698&highlight=477
There are also come good youtube videos. Search on Accucell-6, IMAX B6, or your own and follow some links.

FWIW all those 4-button chargers with the 2 line screen are essentially the same function. There are some minor variations and some differences in quality of the components. Some of the recent IMAX B6 are 'fake' and very bad buy even though they are cheap.

Batteries are a moving target. The cells all come out of a relatively small number of places in Asia. There are probably some runs that are spec'ed for some markets (Thunderpower, Hyperion?) and may be of better quality or are the 'pick of the litter' from testing.
Everyone is looking for a lipo bargain. With the net information gets distributed pretty fast. When a good lipo for a good price gets found word spreads fast. That company rapidly gets overwhelmed with orders. Usually the quality falls soon after that. This is often evidenced by poor and erratic stock levels. Then the next waves of orders start getting inferior products. BUT, and this is a HUGE BUT, with the almost completely random and erratic way lipos are cared for by fliers it is VERY VERY VERY difficult to tell if a battery problem is indeed a poor battery or we have a nut behind the sticks.

Probably one of the things that happens when you buy the more expensive batteries is you do get a product that has had more attention and care in assembly. You also get a more knowledgeable and committed class of flier that knows how to take care of them and does so. That alone can make a big difference. Someone ignorant can ruin a top notch battery in days. Someone who knows what they are doing can get a lot of flights out of a mid-grade battery. I haven't bought a lipo in over 2 years. The ones I fly most often are in combat. I hardly pay any attention to the 80% rule. I do charge just before flying, I always discharge below 90% and usually (recharge) to 50%. I do keep them in zip-locks in the fridge. Batteries not used a long time all go to 50% for sure. It's more of a hassle but I do it because I think it pays off in the long run. I don't know if I have more time than money but I act that way.

Thanks for the advice, fly.

[hghost]

As always great advice. Still tinkering with the Charger and trying to get some handle on it. Charging seems straight foreward, the discharging and storage mod is sort of sketchy in my head anyway.

I never used Lipo's until now, always used other type batteries mostly NiMh batteries. I had batteries laying around for over 20+ years or longer.Some still charged and worked others seemed strange and got thrown out.

These NiMh batteries are to heavy for these foam planes, thus why i always bought Balsa wood and larger planes . Most have been and still are just for show. Years ago as a kid my flight was short and destructive, and the reason why I never tried to fly any more.

Something i always wanted to do and still do...has finally became a reality and a joy. I must admit due to weather and a place to fly, I have been flying the Champ allot. I use 11 -1S 3.7v 150mAh 25C batteries.....I normally am flying for about 3 + hours , sometimes longer sometimes shorter, depending on the winds.
I keep these batteries charged and in a small metal container in the Box with the Champ.

I have an assortment of War Planes and I have been goofing with them some and a Micro T-28 . Crazy as it sounds I have yet to Fly my Cub . Something that is set up to do the end of this week if the weather clears.

From Micro 12" to 30 " -800mm to larger 40-55 ' -1240mm planes that is what is in my hanger. And a host of different size batteries they use. Why I ask about the battery storage and wisdom of how.
The Larger planes I have not tried because of the flying field being a swamp this year and the grass is now chest high.

So...that is why I am reading allot and trying to learn....and wanting the right information to do the right thing to save on battery life and less concern about fires or mishaps and mistakes by me that may cause them.

Thanks Fly for the valuable lessons and knowledge and all the articles


Happy Flying

[toff]

Quite frankly, if you can fly micro planes (twitchy, zoomy little buggers!), then you should find the SC a doddle! Far more sedate and forgiving then anything that small!

[flydiver]

Those little 1S Chiclets batteries....who cares? Cheap. Keep 'em charged and replace when needed.

Larger ones....put at storage voltage, and store in a cool safe place if they are not likely to be used in more than 24 hours.

That style of charger will ONLY discharge at 1A max...so it's s..l..o..w. That's one of it's drawbacks. You have to jump up a significant level to get faster charging or discharging, but then you need a larger power source too.

Storage takes it down to ~3.85v/cell @ 50%.
Discharge takes it to 3.0v/cell (essentially empty), kind of low, and not recommended unless you have a strong hankering to do a capacity test.

[hghost]

Yeah these little batteries have amazed me at how much power they put out and how long they last. yes flying in a Champ, light and easy, still last a long time and keeps
that Champ going even in 10 mph and up winds at times.Not concerned with them much they are cheap.

reason have not flown the Cub is landing , the Grass is super wet and seems every time it starts to dry up I am busy and when I decide to go , it rains again.
The Champ does not matter about wet grass I can catch it when landing if to wet.
I am flying in a small local park, school is back in session so not as many people now, also why i was waiting to fly the Cub there. The large field appears it will not be dry anytime soon...it is empty and belongs to a land company, other than an occasion 4 wheeler going on it, it is in the wild so to speak. Mud bogging type place. No place
to land a plane except in chest high grass or a Mud hole. Grass is as tough as concrete it appears.Mud and water pretty deep.One mistake and mishap there would be one lost plane and or destroyed.

My larger batteries are in a metal box, ( two of them btw )One battery a 11.1v 1300mAh 14.4Wh is partly charged when i was setting up the Cub, 2 more never charged yet, another battery a 2200mAh 11.1v 20C was charged and used little setting up the larger War-Birds and I have a 7.4v 1000 mAh battery that was charged for the smaller War birds I set up. So I have three batteries that are partially charged now...and all the rest are new and have never been charged at all.
I have multiple batteries for each application. I also have 3 7.4v 1500mAh batteries fully charged for my Heli and only 1 larger 14.8v 2200mAh battery for my SBD Dauntless and it has never been charged.

Why I am concerned about the battery situation.

Will these batteries that have never been charged still need to be storage charged or are they not at storage charge or resting charge already ? New only have had them a couple months.

Does every battery have to be discharged after each use ? Or can one just set at storage charge after use ? the discharging I am not sure of..i realize they can not be discharged to low or allowed to be ran to low.....and this charger instructions are not at all clear on set up . I have been trying to get info on you tube, it shows many things some of the discharging and storage videos are vague and or non existant.

But still researching.

I did learn that the auto feature does indeed work well with this charger and does stop user error. This charger also will not work at all if the information is not entered correctly and it will not allow a battery to be overcharged. And if you do not know what amp, or what cell battery it is ( markings worn off etc etc) this charger will read it and charge it accordingly without having to enter the specs. ( you have to know what kind of battery of course) It also has a balance charger set up, so each cell is balanced in the battery

I must say a very nice Charger for the price ( I purchased it at Nitro Partz )

Still have some issues with discharging and storage charge info with it, and have yet to come across a video that shows the settings that make sense.
But still reviewing them.

I can see that it will not allow the battery to be discharged below a certain spec per battery, which seems to be great also has many safety features and many things such as Temp. settings and even a temp probe one can set the battery on and get temp readings and Time set that the battery will not charge to long , it automatically shuts off.

All and all a very Nice charger with many functions that can be set to eliminate allot of user error and or fire hazards.

I like the auto mode, it reads the battery and sets itself accordingly and will not allow a mistake by me.

I did notice on one video from a heli person who stated that discharging a lipo shortens it's life and also fast charging does the same. They were using the Thunder AC6 charger and was making a video of how to use it and skipped around and over the instructions and their use.

Again i am no expert and I am sure there maybe a time one ,might use a fast charge, i watched one person do it and it worked out fine and it to will not allow one to overcharge it or allow the battery to become hot and they have no issues with their batteries. It can charge up to a 6 cell Lipo and one gentleman even charged a 1 cell battery, it took only a minute or two to do so.

It also charges NiMh batteries as well as many other types..all of them set to charge accordingly without mishap. It has alarms if battery gets hot, connections malfunction, information is added wrong etc etc all of it shuts down to ensure no mistake...great charger.

But do not know why so many make claims , if a charger is designed to do it, i would assume the battery manufacturer would have a warning or disclaimer warning saying not to. So as i read many forums I see where many discharge and storage charge their Lipo's and have no issues and many fast charge them when they need to, with chargers that are designed to do so.Also with no issues.

Seems I bought myself a good charger that helps one such as i , not make mistakes as easy.

Still learning and sorting this out.This charger has many functions .

reading and watching videos, I see where many people make claims and I wonder why they bother making a video if all they do is criticize what
they are making a video of. Makes no sense. Some of these unless they have people who will give them some good info and great advice
they would never learn and or get nothing straight and would like i did awhile and that was stay away from Lipo's.
But with everything going to them more and more, you have to and you have to learn about them to stay safe and have fun.

Why I keep coming back to this forum to gain that information and the truth of it.

Thanks again Fly, your expertise is much desired and your help is Priceless to me.

Probably but you can't depend on it. Check them with a voltmeter. Total STORAGE voltage should be around 3.85v/cell.

Does every battery have to be discharged after each use ? Or can one just set at storage charge after use ? the discharging I am not sure of..i realize they can not be discharged to low or allowed to be ran to low.....and this charger instructions are not at all clear on set up . I have been trying to get info on you tube, it shows many things some of the discharging and storage videos are vague and or non existant.

If above 4.0v/cell > discharge to storage or at LEAST below 4.0v/cell. If you want maximum convenience, minimize your lipo damage, and short charging times keep them just below 4.0v/cell.

Approx voltage vs capacity chart:
per cell                 3S
4.20v = 100%     12.6v
4.03v = 76%     12.09v
3.86v = 52%     11.58v
3.83v = 42%     11.49v
3.79v = 30%     11.37v
3.70v = 11%     11.1v
3.6?v = 0%      10.8v

If below 3.85v/cell > charge to storage. When you get down close to 3.0v/cell (empty!) it becomes increasingly important to charge them back up to storage. The longer lipos are left under 3.0v/cell the more damage they accrue.

You don't discharge just for the 'fun' of it or to 'decrease memory effect'. There is no memory effect (there is no memory effect in NiMh either), and prolonged storage at full voltage is more damaging than storage discharge. So, it's a balance of full voltage damage, vs. one more discharge damage, vs. YOUR convenience. Ultimately, you decide.

This is worth watching about [Storage] since the charger is limited. It uses a resistor for bleeding off the voltage > so it gets hot > so it has to go slowly. It can be frustrating if you have a large lipo or several to do.

( you have to know what kind of battery of course) It also has a balance charger set up, so each cell is balanced in the battery.

I strongly recommend you do NOT rely on [AUTO]. VERIFY EVERY CHARGE!!!! To not do so is to dance with fire.

Still have some issues with discharging and storage charge info with it, and have yet to come across a video that shows the settings that make sense. But still reviewing them.

Set on [Charge]. Then just keep pushing the button and you'll get to [Storage]. Setting parameters are the same, except in [Storage] mode you are limited to 1A.
NOTE-At higher cell counts and larger batteries it will actually be LESS as the charger is limited to 50W total. When people start this sport they think a 3S 2200mA battery is a big one. But, it is only 12.6v x 2.2A = 27W.
Go to a 4S 3200ma lipo (47W) and you will max out the charger at 1C. Try to charge it at 2C (not an unreasonable thing to do to save time and it's safe) and it simply will not go there.

Again, I recommend you turn off [AUTO] and learn what you are doing. Verify EVERY charge.

I can see that it will not allow the battery to be discharged below a certain spec per battery, which seems to be great also has many safety features and many things such as Temp. settings and even a temp probe one can set the battery on and get temp readings and Time set that the battery will not charge to long , it automatically shuts off.

Set it up wrong and it certainly will allow you to charge improperly, especially if you have over discharged in flying or some other incident. The stupid thing can't count cells, it can only see voltage. If the voltage it reads does not line up with the cell count you can have problems.
You set it on NiMh charge by mistake (in AUTO), hook up a lipo, and walk away, you get to put out a fire in awhile. It doesn't know a lipo from NiXX, from lead-acid. It can only see voltage an only know how it is set and charge accordingly. If you expect it to be smart....then you are acting dumb.

Temp ONLY works with NiXX batteries. The [Timer] function is worthless for MOST charging and completely worthless for lipo. You don't need to hover like a mother hen but DO NOT rely on automatic functions like that to save your butt, or your house. It's a bad idea.

All and all a very Nice charger with many functions that can be set to eliminate allot of user error and or fire hazards.

Fires are almost always user error. It's evident by all your questions that this thing will not 'eliminate a lot of user error'.

I like the auto mode, it reads the battery and sets itself accordingly and will not allow a mistake by me.

Yes it will. It absolutely will if you don't know what you and it are doing.

I did notice on one video from a heli person who stated that discharging a lipo shortens it's life and also fast charging does the same. They were using the Thunder AC6 charger and was making a video of how to use it and skipped around and over the instructions and their use.

Yet another ignorant flyer giving inaccurate advice. Unfortunately the sites are full of them. It seems if you give some guys a little knowledge they think they are experts.
Using a lipo shortens it's life. NOT using a lipo shortens it's life. Charging it is one more charge against it's life. So it seems ultimately something is going to get it, eh?
Fast charging (within reason and the capabilities of the lipo) has not been shown to do any harm. Like the persistent myth about memory effect in NiXX this fast charging myth persists.

Again i am no expert and I am sure there maybe a time one ,might use a fast charge, i watched one person do it and it worked out fine and it to will not allow one to overcharge it or allow the battery to become hot and they have no issues with their batteries. It can charge up to a 6 cell Lipo and one gentleman even charged a 1 cell battery, it took only a minute or two to do so.

I use [Fast Charge] frequently. It's a nice feature in that it terminates the charge a bit sooner (I won't bore you with the technical details). If you routinely charge you lipos to 4.15v/cell instead of 4.2v/cell you give up very little in power or performance but make longevity better for the lipo.

It also charges NiMh batteries as well as many other types..all of them set to charge accordingly without mishap. It has alarms if battery gets hot, connections malfunction, information is added wrong etc etc all of it shuts down to ensure no mistake...great charger.

It's harder to charge NiMh with this charger than lipo. If you think the lipo instructions are difficult, wait until you try to charge NiMh or have an error code to figure out.
In general NiXX charging is more difficult and technical than lipo. It just has less chance of burning your house down if you screw up.
People ask all the time now how to set the cell count and finish voltage in NiMh (you can't-it doesn't work that way).

But do not know why so many make claims , if a charger is designed to do it, i would assume the battery manufacturer would have a warning or disclaimer warning saying not to.

1. USA Liability
2. There is no liability for the Chinese.
The whole game changed when our fearless leaders decided this would be a global economy. We do get stuff cheap, but we get a LOT of CHEAPER stuff and consumer protection and support are being constantly eroded. My expectation if I buy from China is that I have absolutely no warranty or customer service. This saves a lot of wear and tear on my emotional system.

Seems I bought myself a good charger that helps one such as i , not make mistakes as easy.

One more time....YES IT WILL IF YOU DON'T KNOW WHAT YOU ARE DOING.

I see where many people make claims and I wonder why they bother making a video if all they do is criticize what
they are making a video of. Makes no sense.

Most of the videos on the web are poor to worthless. A few are decent. A rare few are good. Unfortunately you have to have SOME knowledge to even evaluate that. Even more unfortunately the only decent way to get that knowledge is to be exposed to a LOT of bad information and learn 'the hard way'. Kind of like life, eh?

Why I keep coming back to this forum to gain that information and the truth of it.

Thanks again Fly, your expertise is much desired and your help is Priceless to me.

You are welcome. Keep learning, stay safe.

[hghost]

As Always fly , I spell it out and You correct the spelling....Your expertise amazes me.

I will be careful and I will make sure what settings I am setting them at.

I do like the features on this charger, have already seen it will not even turn on without verifying the settings
One just has to make sure the settings are correct. I like that.

I am going to read the article link you gave...

Thanks again for all the info, I sure needed it.

[hghost]

Light Bulb slow discharge of a Lipo ? never would have thought of that

What if one uses their Lipo, in their plane or a bench set motor and have the alarm set on their Tx. to go off when battery reaches that certain volt drop ?

Is that possible ? Many Tx have the alarm set for it to warn you when battery gets to a certain level and as I see the use of the meter is about the same idea.

just Thinking out loud.....

I will continue to test and double check everything i do, until I learn the correct way of to do things

Thanks again Fly
