Checking 1800mAh and 2200mAh packs around the shop with my Wayne Giles ESR meter. Lowest cell IR I'm finding for the 1800mAh packs is around 9 Ohms, a few in the upper 8s yielding max discharge amps of 35A (true C of around 20) and FOM around .75 at best.

Brand new, never used 1800's were the ones around 10 - 11 Ohms. A relatively new 1800mAh pack - few flights - was the one that got the low cell readings around 8.8 Ohms.

Now, where the heck am I going to find some cells with some sixes (6 Ohms)?

Fun stuff.
