Onewheel XR randomly died — Error 16 / flashing power button
My Onewheel XR sat unused for a couple of months.
When I went to use it, the battery was dead, so I put it on charge.
After charging, it turned on, the lights came on for a moment, then it shut off. After that, the blue power-button ring started flashing. At the time, the app also showed Error 16.
I opened the controller, disconnected/reconnected all the connectors and harnesses, and Error 16 eventually disappeared, but the blue power-button ring keeps flashing and the board still won’t work and won’t turn off.
I then opened the BMS, inspected everything, disconnected/reconnected it, and checked the battery voltage — ~58 V. Everything looks reasonably clean, no obvious burns or serious corrosion. Still flashing!
Does anyone have any idea what could be causing this or what I should test next?
Any XR veterans who have dealt with this before? 🙏
If I can repair the original XR first, I’d prefer that. But if I go VESC, which setup would you recommend for mainly city riding, floatwheel XRV kit or fungineers powertrains?
