i charge my battery but no matter what i do it doesnt seem like enough it doesnt even start up my car to clean the motor. it seems like the battery is burnd out or somthing and when i was breaking it in it would rev the motor at 1/4 throttle but it wouldnt move i would have to pull it to 1/2 throttle to move it, what do i do for that and what the hell is wrong with this thing lol its brand new.
