Over amperage trips breaker constantly.

I have a DIY ebike. I have a 60v 3000w rearhub motor. Rated at 60 amp. I just bought a 72v 3000w battery pack that is rated at 80 amp. How do I reduce amp output from battery? I read about resistance but am electronically challenged.

72v 3000w!! It’s the crash helmet and body armour stand you’re looking for buddy!

Your controller should be controlling the amps if you were riding. I assume if you are using a throttle at max amps all the time you will have an issue. You still should be able to program the controller.

I have a 80 amp controller but wouldn't that burnout the mosfets?

I don't know, 72 Volts for a 60 V motor sounds a$$ backwards

I’m no expert but I think 60v x 60A = 3600w. So your motor will be 3600w peak 3000w nominal.
72v x 80A = 5760w! TOO much bro! You’ll cook it!
