The reason you can't use a motor controller outputting 3 volts is simple: You can't get an FRC legal motor controller to output 3 volts. It's either providing no voltage or full battery voltage (in one direction or the other). Inductive loads like a motor will average out the pulse-width modulated battery voltage, but a 3 volt flashlight is likely to be very unhappy with even a brief application of four times the expected voltage.
