Well, been out tonight and bought a cheap temp guage (hope it's accurate!) and popped down to stokes practice night:
Did around 11 mins on a battery, 4 min break to check everything and swap cells then a further 13/14 mins on the new battery, no long straight but was deliberately braking much harder than normal to generate heat, and came off with around 175f on the motor heatsink (motor itself may have Been a little cooler). Esc either much cooler or couldn't get a good Reading.
Hoping that means I'll be ok, wouldn't have thought it would keep increasing much more after 20/25 mins, and it's a hot day!
One question, at the end I did a standing start and it didn't move, the pinion didn't move but it sounded horrible!? Kept running fine after that and with loads of start stops, could it be to do with it being sensorless!??
