I’m getting a Bafang mid drive you see, and after burning out my old Q100 hub motor there’s an amount of doubt surfacing in my mind with regards to safety margins(heat-wise). Reading about the mid drive, it seems there have been incidents of the controllers conking out when push comes to shove, I.E. when you force them uphill for too long or use a gear ratio not congenial to recommendations saying the motor should be run at a high rev range.
Since my commute to the summer house outside of town involves hills galore, it came to pass that my Q100 overheated beyond easy recovery when I caned it one especially hot day.
I’d rather not see history repeated with my new mid drive. The motor seems like it will be able to handle it(the 750w is the same motor as the 250, right?), but the controller might not be as safe a bet.
Could the solution be that I opt for the more powerful 350 watt version and run it on a lower PAS setting roughly equivalent to 250w?
My guess is that the 350w controller has larger mosfets or something or other, a fact which would translate to an increased margin for overheating when run with the output power truncated thusly.
Am I in the wrong thinking this way?
