Setup -
2xVesc 2x190kv6355 lipo 20c batteries.
Identical setup on the same board
Watt hours are the same for 12s or 8s.
LIMITING THE SPEED to 22mph, what is the better way to go, and why?
Considering -
Range
Battery heat
Motor heat
Vesc components
Typically the Higher the Voltage the better, Keeps components cooler, Yet Despite this Esk8 in terms of being efficient is more a matter of Mechanical efficiently , The setup will essentially be the same, because in the end the same amount oh WH is being used no matter 8s or 12s, You wont see the benefits of 12s Speed so you might as well use a 8s to preserve cell life by lowering the amount of Amperage stress on individual batteries.
If you want to reach the same speed with both battery setups the 12S would be more efficient because could use a 33% lower gearing compared to the 8S. But i guess your gearing would be the same in both cases so you can reach a 50% higher top speed with the 12S.
With the same gearing the 12S would be still a bit more efficient because of the lower amps and that means less heat losses but only between the battery and the VESC. I guess in real life you wont feel that difference.
given two identical hub motors except one wound to 50kv and the other 100kv, would there be a decrease in efficiency running the higher kv compared to the lower kv at slow speeds? it seems like with pwm the motor can get any mix of amperage it needs and they would be similar, no? i mean in the motor efficiency mainly but also the esc
