Operating at higher voltage makes the motor much more efficient. The output shaft mechanical power at 18 volts and 26.6 amps is much greater than the power at 12 volts and 40 amps.


The number crunching began, and then I discovered that the 775-12 stalls at 30 Amps anyways, so a clear victory to the -18

I concur that there is plenty of leeway in the breakers before they pop.
