16T, 80T, 20 inch, U15 80kv bought last year on ebay. they're very pricey new... there's almost nothing to them so i'm surprised they retail for what they do. seems like you'd have to really beat on it to overheat it- it's ALL ventilation.
Could you measure the stator in it?
Diameter and thickness of the lamination stack.
Max torque is given by diameter squared x stack height.
I have a motor i think is similar size, and a battery of similar size, but due to months of rain and dark not really had a chance to properly ride it. Wondering what to expect.
Regarding the currents.
1) there's no gains to be had beyond saturation of the motor. It simply won't produce more torque.
2) the abs max current is there to protect against loss of control, it's not a parameter that is "used" it's there as an absolute limit where you say "if it's exceeded, just turn off to avoid fire". So it should be set at a level enough above the motor current setpoint that it doesn't accidentally trip but well within the limits that would burn the controller, motor, wires or battery (or fuse?).
If you're running 200A and the controller sees 300A, unless it shuts down, the next measurement will probably be 500A. At this point it's lost control.
I'd set it at 1.5x the running current, and definitely no more than what the hardware can read (about 480A) under any circumstances.
