I'll check the internal resistances on my packs with the iCharger when I get home. Then we can see if it's reading way too high or what the deal is. Even if the values are off I'm interested to see the difference between the bad 4.09V cell and other cells.

EDIT: My Zippy 2s 30C 5000mah hardcase packs read 2 milliohms per cell when fully charged and 3-4 milliohms per cell when in storage state (3.8V per cell). That seems pretty close to your calculated values BrianG.
