I build a mountainboard:
6374 192KV SK3 motor
6 or 12s Lipo setup
4.8:1 gear ratio
Tried 6s and 12s setups - no big diference in performance and distance. Tried FOC - works, but also lack of performance. I can forget about climbing 5-10% hills.
My VESC last setup screens:
I got basicly 8 km from half 12s 5000mah battery.
All power only for 5 minutes and then max speed about 10-15km/h. When I wait for 5 mins and I get power back for 3-5 mins and then 15km/h top speed. Totaly no hill climb power. My weight about 60kg (130 pounds).
Can somebody tell me where to dig for solving this problems?
Maybe gear ratio? Or my VESC gots too hot? Current limit too low? Temperature limits too low?
