Can any one help me, I just bought this sub first the radio didn't work, I fixed that. Now I turn the sub on. The servos work, but the motor barely turns, and the pump wont turn on via radio. The status lights turn on, then shut's off. I tried charging with and without fuse, nothing. Then I used my digital charger for a few minutes and everything worked. But i don't know how many amps (or C) to charge at, and how many volts per cell for charging top off. You guys are the only people that could help me, Thank You.
