They puff up sooner vs cheap 40C lipo's like Gensace. I have abused my lipo's and they take a bit longer to balance out now. But what else do you expect after draining them in less than 5 minutes.
My two 20C 6s1p packs that has only seen Ebike duty, balance out the fastest. Bike doesn't even give the batteries a workout, but they do drop the most voltage under load as expected from a 20C cell.
My next set of ebike batteries will come from FMAdirect, which are the 60C 6s1p batteries. Good prices and a 60 day warranty. But I need to save up some to buy 8 of them. Goal is to have 24s2p or 12s4p setups with barely any voltage drop. BTW, I charge my cells @4.15V per cell for ebike use, which average out between 96-98% capacity.
I think you found a nice balance between speed, power and throttle response for normal road use.
By the way, what isyour total watts on acceleration ? mine is about 2900 watts, about 33 amps on 24S. It is decent and smooth, but at about 50-55 amps on 24S the acceleration is really good, you should try it if you haven't already.
Only thing is the noise and vibration come back so I have to be easy with the throttle.
The zippy's get very warm and are 20 C I thought they should not be so warm at only 33-34 amps, maybe 50 peak ?that's only about 6 or 7 C average on acceleration at 34 amps ?
Back to pedal only power.
