So then the math for the motor when pulling 100 amps from six 12 volt batteries wired in serious or 72 volts would be to use the formula Volts*Amps=Watts which is 7200 watts or 7.2 kW when maintaining 35 MPH and since 1kW-h=1 watt * 60 seconds = 60 * 60 minutes in an hour = 3600 watts then 7.2 watts divided by 3.6 watts = 2kW-hs of electricity if you were to continue driving for 35 miles at that rate of speed without any amp fluctuation or voltage drop.
Did i see a button on the dash of that thing that said BLOW ME?

How is the open source controller going?

Nice job Ben, I see the AMP gauge jumped to 120 amps with no load; where is it at and at what speed when driving?

If you quickly rev the motor, just the weight of the rotor will pull pretty high amps for just a moment.
The car usually pulls about 100 amps while cruising at 35 mph
I think I also only had 5 instead of the usual six batteries in there at the time.
I still want to make the instrumentation look a little better, but I need to figure out what else I might want in there first.

Yep - in theory.
In reality, I have very well used batteries, and can only go about 20 miles. But that's where hills, the Puekert Effect, etc come into play.
