well, the battery still doesn't quite want to charge properly, the other cell charges, just a lot more slowly than the first one, and I guess my charger isn't so smart as to figure out that it needs to concentrate more charge to the weaker cell. It appears as though it just applies current to the charge leads, and then when it sees the first cell is at 4.2 it goes to discharge mode briefly, and then goes back into charge mode again, the first cell takes the charge more quickly, gets to 4.2, etc. Is this the way most lipo chargers work in balance mode, or is this just specific to the Thunder AC6? Or am I off base on what's actually going on?


In the mean time, I've decided that I'm going to rig up a little switcher so that I can easily charge one cell at a time using the balance plug. I've found some balance leads on ebay, going to put a dpdt toggle switch in a little project box so I can switch between cell 1 / cell 2, and have a lead coming out the other side to hook up to the charger. Even though I'll probably toss the battery soon, it should be generically useful I'd think.
