I'm debating maybe only putting on like 5 - 7 mosfets and 5-7 freewheel mosfets just for the prototype, so it would only be a 500-700amp controller, just for testing purposes. I don't have a motor/coupler/anything that can really test 1000 amps safely. I mostly want to make sure everything turns off and on when it should. There's not a lot of room for error with synchronous rectification.

good news
