Bad battery. The cells inside the battery are misreporting their capacity.

If it's at a certain percentage, it pretty much has to be the battery. There could be something wrong with the charging circuit that's on the board itself, but I have never seen a board cause a problem at a specific percentage. Have you tried a third battery?
