which would draw more amps?

[glassdoctor]

the neu says 700-3000watts, so on 20v, that's 35-150amps.. should i expect peaks as high as 150 amps?

You can't look at it backwards like that. The watt ratings given for each motor are simply what they can "handle". It doesn't mean that they can't/won't draw more amps... or that they WILL draw that amount. It's simply a "duty rating".

It will take X amount of watts to get to a specific speed... no matter what motor/battery setup is used. Watts=horsepower.

Except that one motor is more efficient... so that means the less efficient motor will have more watts wasted as heat, so really it does take more watts to make that motor do the job.

If my ramblings make no sense... no worries... ha ha
