I may have some sort of problem with one of the originals. I've ignored it mainly since I've been using the DNA60 Stormtroopers for weeks. I just checked it and it is dead as a doornail. Battery reads 0v. The bottom of the battery is swelled and probably the top too.
Tossed in a 20700 cell that I really don't care much for and it seems to be operating normally again. I don't know if the cell was at fault, the internal charger slightly overcharges, or what. The battery was a IMREN 21700 25A. I'm not really a big fan of those batteries anyway. I probably bought 8 of them and this is the first one that died.
