Chargers and batterys are not 100% efficient, it is normal for the charger to try to put in more MAH than the pack has capacity for by up to 20% even for NiCad and NiMh that don't need balancing, your buddies battery will probably only give out 3500mah if that, his pack is buggered, do either of your chargers have a discharge mode? if you charge it up then discharge it the discharger will tell you how many MAH the pack will actually give.

.32V yeah that's a LONG way out, I'd be worried about the cell that was .1V out if the other one wasn't even further out, is this within 1 run of being balanced?

I think my charger can discharge but honestly never really looked into it. I just(10 min ago) totalled the front end of my rustler so I will have some spare time to look into it.

As for my lipo it's doing great. I run it 3 times a day but only for a short time and the volts drop to 11.7v each time and now we have been staying over after work and then I run the bat until the speed control kicks me into 50%. They volts are all very very close after I run it for the short times. The last two times I ran it all the way down the volts were only off .03. Not sure whats going on with it. Thanks for all the advice.



Forgot yes I balance every time I charge.
