So no, you don't need a large extension cord. And more voltage doesn't equal more weight. Use more smaller batteries.

And not just's 80hp. Likely that motor puts out something like 120ft-lb of torque. You can direct drive that motor if you could connect it easily to an axle.
You are correct.
We have it currently as a direct drive. We want to "hit it" quicker off the line so a bit of motor speed with an AC motor provides that function.
