I was told that you can't charge a lipo more then 1c With the HZ batteries, that's good advice. Better brands can easily take 2c these days, sometimes more. |

I was told that you can't charge a lipo more then 1c When you are "told" by anyone pretty much in any forum on any topic you ought to make it a practice to determine: 1. WHO told you? 2. Do they have any experience or expertise to support their statement? Most do not, they are just parroting the 'common wisdom' that everyone else is. 3. Can you research it yourself instead of just taking it at face value? If you can, you should. You'll be better off KNOWING in the long run. 4. Until PROVEN, it's often most useful to consider it male BS. There is a lot of that out there. 1S charging is an old standard. It certainly is safe by itself...BUT, it is only as safe as the battery, charger, and the 'nut' attaching them together. Most battery accidents are NOT by 'how fast' you charge but by damaged batteries, junk chargers, or setting the charger up WRONG (wrong cell count, wrong chemistry, etc.). People are the usual problem, not the charging rate. Newer batteries can be charged up to 5C with a GOOD charger, which most definitely is NOT the stock one or some of the $20-30 4-button clones (IMAX B6) |

hghost Loved that reply and very true we are indeed divided by a common language. It also made me chuckle that the word f*g is automatically * the 'a' by the forum. Hilarious, makes me want to try out all sorts of words to see if they get starred. (but I wont) lol

I have a preference for Overlander sport batteries, and they clearly state that you can charge at 2c everytime, and not to regularly exceed this but they can do 5c occasionally.
I do 2c, have charged at 3c at the field when in a hurry once or twice. All have plenty of cycles on them with no issues.

(but I wont) lol I liked that * for the letter a....I thought about that as well...LOL  I figured I might say something, so many people are easily offended now days and I have been called bigot, hater,racist and a whole host of things because I use simple language people do not understand....................plus I can be a little blunt at times .  |

It is amazing how batteries can be charged at multiple rates.More amazing the different answers you get when you ask about them
I use these 1S 3.7V 150mAh batteries allot, most would not even set their charger 1c.....many would swear it would have to be .1c because of the MAh number
I have read where so many say for example if you have a 2200mAh battery to only charge it to 2.2 and that is a fair Safe point to stay at, but also slow
Examples would be , 2200=2.2 , 1500=1.5 , 850=.8 etc etc etc...that is how most charge their batteries and again it is a SAFE idea and a good routine to use.
But if you READ about batteries as fly said many can take up to 5c without an issue, and again that depends on the Charger itself and the battery itself.
These little 1S batteries can actually be charged at 3c rate with no issue and charge really fast and safely.
Depending on the battery I stay under 5c...usually 3c or less, ....depending on the battery.I try and use the concept routine laid out above.
The idea above is a SAFE routine to consider..sure it can take a little time, but I believe so far that has been the safest method to use, 1. because one never knows the make-up of a battery they are using, numbers are often overstated and 2. Many chargers boast abilities but again many are hyped and not correct and no stock charger should be depended on to be accurate at all.
READ what the battery states, Read the charger Instructions....and charge in Lipo safe bags and on a fire resistant surface and NEVER EVER Leave your batteries unattended when charging .
Safety is always the best method to use.

The little stock charger that runs off 4xAA from Horizon that charges the little 'chicklet' 1S is about a 3C charge rate. *** It's actually not amazing that lipos can be charged at multiple rates since balancing chargers came out. You can charge any chemistry (NiXX, Pb) at multiple rates just fine, BUT the others don't do terrible things when overcharged for the most part. Lipos do. Not all that long ago the manufacturers took some serious time to match cells and there were NO BALANCERS. So, lipo needed to be charged slowly to prevent accidents. Chargers have improved significantly and balance charging is pretty much standard. This allows faster charging while still being safe. Attempts by manufacturers to match cells isn't very good anymore, but they are much cheaper and for the most part performance is better. Trade-offs. |

One mod' I am pretty sure I will need very soon is one, possibly 2 larger batteries. What I do need is some advice as to which ones, and, how to charge them. Turnigy 2200 3s as previously mentioned, but what else should I look for in terms of connections etc? Any help greatly appreciated.

If you buy from RCpitstop.co.uk you can specify the connector on most batteries. So you can pick the EC3 that's standard on the cub. They solder them for you.
I've found OverLander batteries to be pretty good
