They don't know if it's the battery or the charging circuit I checked my battery and it's fine the charging circuit is also putting out 12 volts so I'm not concerned about it it takes 6 18650 batteries, take three of them put them in series, take the other three put them in series, then parallel them together for the extra amperage and you have the 11.1 volts that you're supposed to have. I pulled the little plastic plugs out on the bottom of mine unscrewed it and there was the battery pack is playing its day it's just shrink wrap together
