The other issue is going to be sag. You’ll sag down from 4.2 to 3.4 at 15 amps with those cells. That means 6.8 x 15 = 102 watts per motor x 4 = 408 watts total. Range will be like like, 15 city blocks before your sagging below the low voltage cutoff at 15 amps at best, probably more like 5. Again, assuming 15 amps is even possible.
Again, not trying to tear this project apart, just giving my analysis of the concept. I’d still love to see it done. Maybe you can prove me wrong?
Either way, it’s clearly misleading to say high torque or high speed. The Carvon EXO uses the koolwheel motors, so it’s limited to 700 watts total. At that even the acceleration when I tested it at the SPD2 was very weak for my taste (not trying to hate on carvon, just trying to compare watts with what I’ve ridden before).
