I upgraded my 7s battery to 10s and went from a ying li 7s esc to a hobbywing 10s esc from ownboard (Ownboard.net: Electric Skateboard 2.4GHz Remote Controller – ownboard) My hub motors are very similar to the 70mm maytech (https://maytech.cn/collections/in-wheel-hub-motors/products/brushless-hub-motor-hall-sensor-motor-mto9055hbm-100-ha) just a different cover same wiring.
The ying li with 7s could go up any hill no problem. This hobbywing esc now won’t climb before it starts to cog. Even from a standstill if I go half throttle it starts to cog. I can grab the wheel with my hand (somewhat difficult) and it will cog or jitter.
I’ve tried swapping the wires on the hall sensor and also the main power wires with no luck. It works fine with little load once it gets going. Any ideas?
