Hi Wut
Your location is important - please put it in your control panel!
CALB and the others are NOT the best bet for cells these days - cells from an actual EV are a much better bet
In fact for what you want I would say that getting a wrecked EV as a "donor" car is your best bet
You will get all of the stuff you need - for a lot less money!
As far as power draw is concerned
Torque is basically proportional to current
Speed is proportional to voltage
So if you get something with a controller that will give 700 amps
You will start off - 700 amps - just a few volts
Then 700 amps - more volts
Then - not enough volts to maintain 700 amps so 600 amps - full battery voltage
Then - not enough volts to maintain 600 amps so 500 amps - full battery voltage
See how that works?
I would have said get a Leaf - one that still goes if you can
Once you have it working then you can look at the guys working on getting more power
Or even stick another Leaf unit in the other end
