I am wrong about MaxAmps.

What cell do you want to see specifically? This is a new version of the 4000 cell vs the old version. The factory rates it at 4200mah. We rate it at 4000. This is the same cell that we use in our 8000 packs. At 20C, you can see that it holds what I would consider great voltage. I don't know how you could not call it a 20C constant cell based on the data...
