Hi
48 volts car will be awesome! Like you said, only 16 cells, easy bms wiring, safety, etc.
But do you realise than 48v and 400A is only 16 Kw at motor shaft? It's a poor power. And your peak power with normally availiable controller (1000A) will be only 40 Kw.
And at such high amp, you need a lot of copper to have good efficiency. All wires, motor, battery, controller need to be stronger to pass high amp continously
Many of us need to go at high voltage because we need good performance electric car. My car for example, can give 156v (130v sag) x 1000A to have around 105 Kw at motor shaft.
Also, at high voltage, I will probably need less than 100A to cruise at relatively high speed (80 km/h, 50 mph).
48 volts electric car will be good idea only for a city car with poor performance(always under 60 km/h, 37 mph). Over that speed, you will need too much power and more power at 48v = too much amps.
