Building my first Single motor E board with a 6364-245kv & VESC. I will achieve intended speed with around 8S , but according to Vedder theory on how to choose , 10S would be better ??
So either 10S4P or 8S5P ? Your thoughts ?
higher voltage is better because you will have lower average amp draw and achieve the same power output. Depending on your desired top speed 245kv might be a bit high at 10S
either way, the Watt Hours is still the same, so range and charge times remain the same.
so the benefits are
- lower amp draw
- less heat
- slightly more efficient
I’d go 8s5p. 245kv on 10s even with serious gearing will be VERY fast.
I have a 6364 turnigy 245kv running on 6s: With 15/36 gearing I’m hitting around 25mph.
You could run something like 12/40 gearing on 10s, but you’d have a small amount of contact teeth on the motor pulley; less contact teeth means more belt slipping. Even running 12/36 can have a significantly worse effect on breaking than just 3 teeth more at 15/36.
if you had a slightly lower KV motor, 10s would be the winner for sure- but with the higher speeds and gearing changes you’d have to do (unless hitting 45-50mph is all cool with you 
) I think the lower voltage will be better.
I was thinking of making a diy Belt deflector(tensioner) to get more teeth in mesh with a 12T motor gear ,…that would give me a 1: 3 gear ratio and 6 teeth in mesh ?

ya, that’d work for sure!
looking forward to seeing how it turns out
