Yes, that's what I've been doing. It seems that the output is so low that it takes a long time to charge from 3.36 to 3.38v, after they hit 3.55v they charge fairly fast. It's the waiting methinks.... Took me some time to get it right...

I have 3 cells at 3.74, one at 3.36, then it gets a little wierd - I had hooked the 36v charger up (after an initial charge and waiting, watching the cell voltages drop to around 3.43v or so) and the two end cells peaked at 4.2v as I caught it. I was a little nervous for a while and now they have stabilized at 3.75 and 3.8v....

I had intended to stop at 3.65, but went a bit higher to match the two I almost cooked.

Also thinking I'm going to place those aluminum plates under the velcro straps for extra protection one the sides of each pack.
