Thanks for the replies.
If I am understanding correctly, you are measuring a Tx pack (Presumably 3S?) and also measuring a normal 6S pack as well and in both cases Cell 3 is reading 280milliohms? If this is true then almost certainly the measuring device or the interconnection is faulty as John suggested. The 280 reading is almost certainly the max reading that the charger can read, so that any overange will read that value.
