Thats odd...I wonder why they would add a pin...Danke, I'll give that a try, one difference between authentic and clone is the clone has a little "pin" placed on top of the connection area, where the authentic is flat (from what I saw), we'll see if I can get things to balance out better, didn't want to mess with it too much, finally got the batteries all balancing right
Tightne the batteries like lugs on a car...bit by bit on all three until they are snug, dont do one at a time!!
