haha, i understand that it balances the cells because of the way theyre wired in the pack, but my point was i dont understand why lithium polymer batteries arent wired in a series in the pack. All the crap i read on the net didnt mention the dangers behind them, so i scooped some battery bags too to make sure everythigns good. I emailed HPI yesterday about a brushless system and lipo batteries and they recommended LiPos before the brushless as they claim the 15t is an excellent motor and that my current battery is not even tapping into the motors full potential. Im waiting now to hear back about the ESC.
