Pint controller repair
-
I took a Pint controller, both boxes and a stock battery but no bms in part trade at $50 value. However, the controller suffered damage from a vnr that shorted out.
Testing the controller revealed a massive short that blew the fuse on my test harness.
Probing with a ohmeter showed a short between a phase connector and ground, so further testing came up with shorted mosfets controlling that phase connector.
I didn't have new mosfets, but I had harvested a few used ones, it was straight forward hot air replacement. I ordered new mosfets now TPH2R608NH
The controller works well now and been patched with Rewheel.

@lemur Nice work!

I’m fixing the same thing myself, I undid the solder on the same mosfets on the controller but they still won’t come off the board. Is there solder underneath too that needs to be taken off? If not how did you manage to remove the mosfets
