Oh #%@!! What did I do to my SMC Lipos?

Maybe this was mentioned somewhere in this thread, but it looks like both packs puffed. Maybe it's just the angle of the pic (first one), but the one on the left looks puffed as well, just not as badly.

On a side note, I'm not really sure I like hard-case packs. Sure, they protect the lipos physically, but if they are tied down well enough, that shouldn't be a concern. My beef is that having packs enclosed doesn't exactly promote good airflow. And if they get too hot, they can puff. Maybe they were ok amp-wise, but since there was no cooling, they puffed anyway?
