Interesting project for me, so I'm thinking how if we using Li-Ion combine with ultra/super capacitor, offcourse using fast switching mosfet between them, let's say if possible the 2 motors works alternatively left/right during straight run, must be researching the duration so the passanger not...
I think need the wheel diameter to get the torque n speed of the output motor after gearing/rpm on the wheel shaft for max speed 15mph, how many kg/lbs for the 40Ah Li-ion batteries?. Thanks
