I knew I'd see this. I had the same thing happen with my SMC 2S 6000mAh 24C hard-case LiPos. Conditions were:

Losi 8ight 1.0 buggy w/Tekno electric conversion
Tekno/Neu 1512/2.5D/Q motor
14/48 gearing
Racing at Indy RC World (Garland, TX)

I had been running a 16T pinion for a little while (about 12 minutes on the track practicing) when I brought it in and noticed the packs had puffed about 5mm each. They were also at 135dF when I pulled them off the buggy. Putting them back on charge brought them back up to 8.4V, the puffing went down to about 1mm each, and they took about 3000mAh back in. Gearing down to 14T, they did better, coming off the track puffed about 4mm each after a 15-minute main, at 130dF. Once again, recharging them took care of most of the puffing.

I don't want my LiPos coming off the track puffed up.
