Uh oh, did I ruin my SMC Lipo's?

Uh oh, I think I screwed up. I just took my Savage Flux out today and I might have pushed the Lipo's a little to long. I"m running SportMax 6000mAh 28C 2S Lipos in my Savage FLux and I've been running the stock 20/44 gearing and i've had punch control at 30% with 15% brake drag, 40% reverse throttle with 3.0v Auto lipo cutoff set on my Castle link. I got around 31 minutes of run time of mostly spinning around in the dirt and high speed runs when I started running the truck in circles in the grass when the LVC started to kick in but I wasn't sure cause the grass was bouncy so I think I kinda went overboard. When I got home, the batteries felt warm but not hot and I dunno wether it was just me but it seem like they "puffed" slightly on the outside casing.

I did notice that my motor and my ESC were pretty warm as well but I never heard the fan kick on the ESC.

Did I just make at $190 mistake? I immediatly threw one of the batteries into my Triton2 EQ charger and initial voltage reading was 7.02v before it started to charge. I've balanced these Lipos from day one. Right now its charging at 6.0A and its behaving fine, and both cells are showing very close voltages to eachother, but im really worried I mighta bit the weeny on this one. Any incite?
