What is the difference between 24V, 36V, 48V or 72V? How does it affect performance?

A: Voltage has no mechanical effect on the ebike performance. This is a parameter which is set based on electrical characteristics of the motor/controller and wiring. Voltage in Li-Ion batteries is a matter of number of cells in series. Increasing voltage helps maintain a lower current on same power rating which makes it easier to maintain the electrical efficiency; on the other hand lower voltage offers more safety.
We have standardized 36V for our street legal conversion kits. Our regular ebike battery packing and wiring is capable of 22A continuous power which is equal to 800W at 36V average voltage. There is no considerable voltage drop for up to 800W peak power with our LG 10.4Ah (minimum recommended for our 500W system is 10.4Ah). The peak current is 25A and the peak power 900W and the voltage drop is less than 3V in our system (all wiring resistance included). There is no advantage in 48V or 52V over 36V for up to 500W rated motor class. There are also some safety concerns for above 42V electric products including battery chargers in some provinces. We have 48V or 72V battery and hub motors for off street use up to 5000W rated power.
