My board is experiencing some major issues. First a backstory.
I had been running a focbox for a while in FOC with no issues. And suddenly I started getting DRV errors when I’d accelerate hard. Since then, I’ve swapped to dual focboxes. Both brand new Dual Torqueboards 6355 190kv Dual focbox in FOC VTC6 10S4P with Bestech 80A BMS
Started with: Battery max: 50A Motor max: 80A
Since, to try fix it, I’ve decreased battery max to 30, and motor to 60. Doesn’t fix it.
When I throttle hard, and the board cuts out, my metr module tells me I get a DRV error, and an overcurrent error. At the same time, the voltage drops to 26V or 15V (nominal is 36V with 10s pack). This recovers fairly fast, but did land me on the floor hard the first time I experinced this error. The very first test ride I did with this setup went flawlessly. Pushed the board hard and nothing went wrong
Here’s a metr record of 13 total errors:
Some help would be amazing!
