BBSHD burned up at 72V

SwampDonkey · Jul 22, 2020

How are these drives surviving 72V? I just killed mine in a few mins running a full charge 72V pack through a Luna "tiny sinewave" controller. Is it too many amps? I hear they run fine on ERT controllers and phaserunners. Mine got super hot and died after a mile or so of generous throttle.

I guess the good news is that you got the controller working?

These use external controllers right?
I have a BBS02

Sounds like you got the phase wires wrong and was in the "turning but low torque and running hot" combination.

Not quite. It ran hot and at about half the power it should have had. I was out testing it when it fried. It felt less powerful than a stock BBSHD actually.

Yeah for sure. There was no working combination unfortunately. 2 other controllers worked fine though. Its a shame, thing looked great.
