RC boat rebuild Answered

I have a bit of a dilemma with an old rc boat that I'm retrofitting with the board from a cheap rc car that I bought at walmart. The boat is meant to run on two 9.6 volt motors, but the radio board is designed to only handle 6 volts. Is there anyway to utilize the motor leads from the board to trigger some sort of circuit that would allow the board to use it's original 6 volt power pack while supplying the motors with 9.6 volts from a separate battery?

You will best use a couple of N channel MOSFETs to drive the motors from the higher 9.6 volt battery with a common ground to the 6 volt battery..

I don't know if that RC car board supplied current to the motors or if it drew current from them ?
