My board is an Enertion Raptor 2.x that I pieced together from clearance parts, including a FOCBOX Unity. It’s pretty much all brand new with under 10km on it.
I was out for a ride today and stopped to pick up the board after deciding against going over a rough patch of pavement.
When I set it back down it wouldn’t move, so I checked the BMS gauge and it said 0%. This is kind of unexpected because I had gone less than 1km on a 90% charge, and yesterday I took it on a 5+km trip and used maybe 10-20% of a charge. I carried it home and put it on the charger, which finished charging it in only a few minutes (making the 0% reading even more implausible).
The power button/antispark switch didn’t seem to do anything (i.e. holding it for 5 seconds didn’t turn off the little ring light around the button or the battery gauge backlight like it normally would). When I got home it was completely off, however.
Now the power button does nothing, and the spare power button I have also does nothing, whether the unity is connected to a bench supply, a known good battery, or the raptor battery.
I’m able to power it up via the SWD connector, and at that point I can connect the VESC tool via USB-C. I’ve tried re-flashing the boot loader and re-uploading the firmware, but neither helps. I’ve also tried changing the “Off after 30 minutes” to “toggle button only”.
I’m beginning to think this might be a hardware problem. Has anyone else had this happen?
