new lipo battery problem?
I have a new 4000mah 15c 3s battery with a full charge it will not let me pull more that 7 amps. If I throttle above that the voltage instantly drops from 12v to 9.25v ish and the motor starts to die.
Its 1 of 3 hong kong batteries and the other ones ar fine. Any ideas maybe a few low amp draw cycles will bring it back what do you think?
