Display battery level off after rear tire change

[FreddyL920]

I have an Ancheer blue spark 27.5" 350 watt bike. After charging the rear tire I find the battery level on the LCD display is at 1 bar or less, despite battery being fully charged. Any idea how to fix ??

Thanks for your effort. I checked all the connection points.. After searching YouTube I found the solution. Somehow the setting had jumped from 36v to 48v for the display. Once I reset the display ( not a simple off & on) it works fine.. a shame Ancheer does provide more thorough information.

I believe the specs were 350 watt 36v 10.4Ah...I'd have to check the original description ...

It's held up well so far...just difficult to get troubleshooting & repair info...and very few shops have a clue.

Good to know...I'll keep that in mind

So I found a YouTube video on the controller, and I checked the volt setting. It had jumped from 36v to 48v, ( likely when I had the bike upside down changing a tire). Once I changed it back to 36v it works fine
