LiFePO4 balancing question

[ta_man]

I had one of the 2S Turnigy LiFes that was out of balance on the first charge. I put it on balancer mode until it evened out and ran 4 half cycles on it (discharged about 2200 mAHr and recharge). By the 3rd or 4th cycle the pack stayed balanced very well (within .01 v).

BTW, I'm doing the half cycles because of some product description info I read on a LiFe pack sold by A-Main - said not to take them down more that 50% for the first 20 cycles. Is this is real issue?
