More testing of the 144V Cougar.
It went up the one really huge (and long) hill in my area. Car went up it just fine. I was cruising up it at 35 mph at 300 amps. That would have been 600 amps on 72V! Yipes! High voltage works much better!
I also tried a little more gravel spinning. I was hoping just to drag the car forward, but the parking brake wouldn't hold!
