OCD:
The cure is to connect two in parallel if you want to run a 3000 watt 80 amp controller.

e-lmer:

Just to make sure I understand, are talking about pulling
(48V * 50A = ) 2400 Watts through a 1000 Watt motor?

That can't end well.

OCD:
Actually the controller is rated for 80 amps which would tip things well over the 3000 watt (peak) mark. If you can run the motor hard and still put your hand on it, it'll hold up. I've been running a 3000 watt 80 amp Greentime controllers with Pro 901 motors for a couple of years with no problems, if things get too hot you could always drill some cooling holes in the side plates but I haven't needed that yet.
