I've had couple of 20c packs that came out over 140 degrees (balloon like).
How do you cool them down? I've seen some Japanese using PC Fans to cool the motor/esc when plane is on the ground.

Bob Violet sells a piece of aluminum that you rest the packs on to wick the heat out so something along those lines. putting the pack in a ziploc bag then into a shollow bucket of water would probabley be effective too. I shorten my flights, as mentioned above
