I got a little info all the lipo guys. Upon getting my lipo pack everyone told me not to worry about balance charging while at the track.
This is not true because if one cell gets a little off it will cause the other cell to slightly overcharge thus giving you the "puffed Pack."
I found this out the hard way, and was giving the correct info by Steve Rodgers of trakpower. Really good company even though I didnt bal charge they still honored the waranty.
He also said not to trust the lipo cutoff feature because the amps and voltage change as you accel and decel. and even though the cutoff kicked in your voltage could still drop below 3 volts per cell.
He finally said that balance charging will take the same amount of time once the cells get into the routine of being balanced.
I know wrong thread for the post but we dont want any flaming lipo paks down the 200ft straight.
