I got my new Gotway Msuper3 1600WH 84V yesterday.
It was at ~25% charge (according to WheelLog) out of the box. I charged it up to ~50% before doing a very short test ride, 100-200m, and it worked fine. I continued charging it and went to bed. This morning all 5 lights were blinking twice, one short, one long, continuously. I'm not able to power it off using the power button. The wheel does not run. I let it stay like this and went to work.
When I came back, it's still blinking the same pattern. I found a youtube video on how to disconnect the battery (https://www.youtube.com/watch?v=IF2ygW7L-jY), but when I reconnect the cables again the same pattern starts again. The wheel does not work, there's no other lights, nothing happens when I press or press and hold the power button, and there's no sounds from the unit. I can't find it as a Bluetooth unit anymore.
I made a video showing the lights blinking: https://youtu.be/zdh_U7nHLzA
Any suggestions guys?
