It's pretty low on the current handling side of things for a heavyweight. 20A continuous with peaks of 70A. That's closer to some featherweight ESC specs. I run Coyote on two 24V 800W scooter motors and use a Vantec 47E, which is 80A continuous and 220A peak, though that was down to getting a second hand one for a good price. If I was to buy brand new, I'd maybe look at something lower range.

A Ragebridge controller would be a better and cheaper option compared to the 23F, at least for NPC drives. Can't comment on its use with Ampflows though.
