I don't have a separate charger and balancer, so when I say "cycling" the pack, it is being balance charged (on the most accurate mode with trickle balancing at the end), then it discharges down to about 3.4V per cell, then the cycle repeats.

I did this 3 times yesterday and actually got the cell to balance. I still think the one cell is always going to drain lower, but I have yet to test the pack. Any of my other packs balance up perfectly with one balance charge, while this pack took 4 cycles on the slowest, most accurate balancing mode. The weird thing is that both the suspected bad cell and good cell have the same internal resistance (2 milliohms when fully charged).
