I’m unsure as to that. We know voltage spikes when braking, I’m just not sure why it spikes. I’m thinking the spike is the reason we’re able to regen given the higher voltage compared to the battery.
Another instance of reaching a higher voltage than the battery is when going fast downhill or when your battery is at a lower voltage, or both.
also keep in mind that the vesc could lose the motor for a few milliseconds if you go over 60.000erpm and probably will lose it going over 100.000erpm. The result is a stuttering motor which can throw you off the board, depending on how much the motor stutters (Not to mention a DRV Error). If you limit the motor to 60.000 you shouldn´t be able to exceed that with throttle, but i´m not sure what happends if you exceed that going downhill without throttle…
for safety reasons i would do the math on how fast i can go to not exceed 60.000 and stay under that speed
