Novak HV4400 and 7XL BL Sensored System...

I was merely asking what the current handling capabilities of the stock HV-maxx ESC were, because they must be quite high if it can handle the 7XL. Novak havn't released many specs to do with the HV-maxx controller, so I wondered if anyone knew?

Thank You,

With proper cooling (stock fan works fine) up to 400A continuous per phase, 1000A peaks. Datasheet specs. But I will say 210A to be safe. Two FET's (IRF3703) per phase 210A each, 2.8mOh Rdon

To sum this all - 1.73*210=363.3 average :)

Enough to move motor wires if timing wrong.
2 to 5 times more starting torque then same motor with sensoreless ESC.

P.S. In stock form ESC is pretty good, HV-motor sucks...
