iHelp101 Posted June 17, 2016 Share Posted June 17, 2016 I have had my generic electric unicycle for almost a year now. A few days ago while riding at the park I experience my first ever unexpected shutdown. Luckily I managed to prevent myself from falling, but I now don't trust the unit. The unit would not full power on for about 10 minutes. I would hit the power button, it would beep, and shutdown. I lifted the unicyle will powering it on to see if the wheel would speed up, but nothing. The battery was at around 60% power when the shutdown occurred. I would assume with was a BMS shutdown. Do any reliable vendors sell batteries without this shutdown circuit? I understand that you can do a shunt modification, but it is not something I am personally comfortable with. Thank you for any help provided. Link to comment Share on other sites More sharing options...

That's what was specifically asked for here. Didn't see much any descriptions of the battery on that page. Link to comment Share on other sites More sharing options...
obus Posted June 24, 2016 Share Posted June 24, 2016 I do not know the technical details, but shared this battery that is cheap and that it knew. I apologize. Link to comment Share on other sites More sharing options...
