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
