More Voltage = Less Amp Draw?

[glassdoctor]

My system is pulling 60A at 15V (4s) on a typical full throttle accleration... 60 x 15 = 900 watts.

So to get the same 1.2 or whatever, horsepower (900 watts) using an 8s setup would only need to pull 30 amps. Which also means less heat, more efficiency. Also, because of the lower amps... the battery voltage will not drop as much, so you need even less motor to make that 900 watts... or you get a little bonus... maybe the battery holds at 31.5V instead of the 30v... that's 945watts.

Hey that's 45 watts for free... so I was wrong about the nothing for free thing. :)
