Thanks for the replies chaps!

Just for the record, these are Gens Ace 4S 2200mAh 25C packs. I've measured identical packs previously at between 6 and 8 millohms when received.

Wayne - I'd read all through this thread and already knew that IR falls by up to 25% in the first few cycles. However, these are now reading approx 15 milliohms per cell at 20C, so There's no way they're likely to fall to under 8 milliohms with use. IMHO, they should be around 6 milliohms at first, then maybe fall to 4 or 5 after a few cycles.

John - These are labelled the same and are identical in every way that I can see to previous packs from the same supplier.

Gordon
