then you gotta do some oddball stuff with CVTs or maybe an electric motor driving the flywheel and acting as a generator the other way round. Eh, seems easier to just dump the electric into caps and then do whatever with it from there.

Main difference in the high volt stuff versus the low volt stuff is the amperage and therefore size of components required. You can get a lot more wattage through a #1 gauge cable with 400V than with 48V. Same with the transistors in the motor controller, more power through smaller components with higher voltage.

I'm currently picturing a setup at about 60v with 5 batteries. Make up a go pedal with carbon contacts to power it from 2, 3, 4, 5 of the batteries for smoother starts. For winter braking have a separate pedal that shorts the motor to stainless rods as heating elements. Summer braking just use the normal service brakes. Maybe go with an even number of batteries and work out one hell of a series-parallel switch so you get even discharge across the bank.

voila, caveman tech electric car
I've gotta fit my new interstage intercooler, not fiddle with thinking about electric cars, haha
