Hi there. I'm scratch building a large RC warship with lots of working features. I need a varisistor for speed control.

I will be using 2 6vdc 7ah batteries which will give me 6vdc @ 14 ah and -with diodes- 12vdc @ 7 ah. The screws will be turned using 4 perm magnet motors. Thus i need to get a good versistor or whatever for additional speed control. what would you suggest?

Thanks

I think you mean using or-ing diodes, you can run the batts in parallel (6V 14aH). In series (6+6=12V), no diode is needed. In any case, if you want to only go fwd, a PWM low side fet (meaning switching…
