Deepest voltage drop: 10.77V / 3s = 3.59V/cell

I think you have nothing to worry about. Your cells are up to the job. But there might be a larger drop in voltage at 290s when you look closer at the graph. 10.77V x2 (packs) x 100A = 2154W peak.

Dang, those things really are pretty darn good, considering the C rating. My Hyperion G3 35C packs (4200mah) hold around 22C at 3.7v/cell... so those Turnigy's might even be the same cells as the 25C, 30C versions...

Although the G3's only get more powerful as they age, so I've got nothing to worry about. Whenever I get my Eagletree working again (installed latest firmware 6.93 and it doesn't want to work now) I will post some more discharge graphs. I also did my first 5C charge on them last night and they did great! Stone cold and held CC phase for the majority of the charge.
