Should have also mentioned a law, watts=volts x amps.

Double the voltage, half the amps, have less watts lost as heat. Quadruple the voltage, quarter the amps, much less lost as heat. Assuming your keeping the same power output (wattage) at each voltage.

Hard to pull off high voltage with brushed motors, consider going brushless. Much higher efficiency right off the bat.

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
