If I got a 36v 1000W motor and a programmable controller (e.g. Kelly) could I program the controller to run the motor at lower speed/power? I'd be hoping that in that trade-off my amp-hour usage would also go down so my batteries would last longer.
I suppose another way to ask it: can a higher power motor be run as if it was a lower power motor - with all the same trade-offs in performance and efficiency?
Or should I just buy a smaller motor now - maybe a 36v 500W - and then in a couple years upgrade to a 48v 1000W motor.
BTW- I realize that much of speed is related to gear ratios and tire size. For the sake of this question I'd like to focus on how much a "smart" controller can, well, control.
