Got our tester today. Shows our A123 cells here (we are a U.S. distributor for A123) are right at 8.3 at 75 degrees.

It also shows us that our 5000mAh 65C cells are 1.9-2.0 (new, not broken in) at 75 degrees... but, our 2200mAh 65C cells are showing as 4.9-5.1 (new, not broken in). We are going to test a few here to see how much these come down. We checked dozens of packs today and found none that were way off like what Charles receivd.
