Reply to "Motor Voltage???"

OK. I misunderstood what you have when I saw your initial comment about AC voltage.

You are correct. Your board does NOT have a bridge rectifier. The maximum voltage your DC motor will "see" is essentially your battery voltage...less 0.1V or so. What that board is doing is rapidly pulsing the DC motor with the full battery voltage. By adjusting the ratio of the on-time to the off-time (based on your remote control throttle setting), the effective motor voltage is controlled and hence the speed.

But the "math" is the same. By going from a 3S lipo (11.1V) to a 4S lipo (14.8V), you will up your max speed by over 20 sMPH.
