First let me say I'm new to this hobby and I know nothing about voltages. I'm looking for a battery charger so i can charge the Park Zone battery I got with the cub at the flying field. (I have three now) Before I purchase this, will it charge my batteries? LINK: www.hobbyking.com/hobbyking/store/__14857__HobbyKing_50watt_5A_X_Charger_Balancer.htmlMy plan is to take my lawn mower battery to use with the charger. Sorry, I'm still learning this stuff. So far I've been charging off the car plug that came with the plane or off a friends charger and his battery, which was much faster. He paid almost $200 for his charger. I'm wondering if this inexpensive charger will do the same. Some of the guys at the field seem to have far less expensive chargers. I'm not "voltage savy" LOL so I'm asking before I buy the wrong thing.

I looked at the charger on the web site that you gave, and I saw the different balance ports,and it has the one you need for your battery, just make all the right settings for your batteriers( three cell) When it comes to voltage, picture a garden hose with the water on, the volts= pressure of the water comming out, & the amps = flow ( rate of the flow is equal to the size of the hose ) I hope Im not confusing you ?

Wow, HK has taken the absolutely CHEAP Accucel-6 and made it even CHEAPER! IMO, this race to the bottom is in serious risk of breaking down and this kind of product is pushing that line really really hard. That charger is based on an American product (admittedly made in Korea) called the Bantam that costs more like $100. The Accucel-6 is only a bit more and worth the extra. www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7028I can't help but think this product is seriously compromised in a number of ways. I don't KNOW that but for it to be that cheap there just have to be some shortcuts. If you go there....well you'll find out. Personally, I wouldn't do it. I seriously dislike the Horizon chargers as the are just as lame (more actually), but I'd recommend sticking with it and doing a LOT more reading before you buy that one. If you are really electronically 'challenged' buy a FMA Cellpro 4s, you will not be disappointed. It's easy, it's SAFE! It has American backing and support. It is a WAY better charger. www.revolectrix.com/4sgold_description_tab.htmIt's pretty hard to screw up. Read Dillzio's recent event on trying to burn his bedroom down using a charger identical to the one you link to. He made a mistake. No one plans to make a mistake that can result in a house fire. It CAN happen. I've done it and I'm pretty careful. How to not start a firesupercubclub.proboards.com/index.cgi?board=tt&action=display&thread=4510&page=1If you don't know squat...don't buy until you DO! One of the more vexing aspects to the sport now is the easy entry and almost complete lack of information about lipo and charger use and care until a good ways down the learning curve. Crash a plane > get a new one. Burn your house down.....well...get a new one. A charger decision deserves some thought, and more than just how cheap it is. Expect to spend 50% more for a power supply unless you are content with your mower battery. Likely it won't live long unless it's pretty good sized. This may not help you decide but it will expand your base of confusion a bit. www.rcgroups.com/forums/showthread.php?t=1356436

Take your time. There's a lot to learn, just on lipos alone, let alone chargers and all the rest of the electrical stuff. The average newbie probably ruins a half dozen lipos before they figure out how to use them properly and not crash them to mush. Be careful to NOT (like in do NOT) fly to LVC if you can at all avoid it. The LVC on the stock ESC is set too low (They really wouldn't do that would they? Yes, they did). If you over discharge the battery the stock charger will not charge it. Then you are stuck until you get a better charger that can.
In addition it is not good for the battery. You would like to leave ~ 20% of the capacity, which translates into ~ 3.7v/cell after you quit flying.
If you seriously over discharge it (stick it in a tree, forget to take the battery out after flying - it happens all the time) then it's ruined.
