  I bumped the neg lead from the chager, disconnecting it.  Now the batter reads 5v at the teminals and 13.3v on the app.  Charger won't connect (doesn't see the battery?)  I did connect another battery to it to see if that would wake it up though I didn't expect it to work. 

  Is there a fix?  

  Battery is a 12v MIni with Blue Tooth.  

  Thanks

  Steve

  How hard did you bump the batt terminal?

  Did you see sparks on the disconnect?

  Best chance is to remove the cover of the battery, unplug the bms and then plug it back in.

  It is easy to remove the cover if it has 6 little plastic plugs on top, covering screws.
