IE, if I run it up to 3.85V at 22deg C and measure the IR on my iCharger I should get numbers around 1mOhm per cell or lower, correct?
yes correct. I'd personally use something more accurate then a RC charger. Do remember that IR in battery industry is AC resistance and not DC as the iCharger and other RC chargers calc. Its close but not exact. But yes. We use pure IR measurement machines (ac 1khz) and we stand by the cell IR spec measured on the cell terminal exactly.
