What to do with my puffed Turnigy LiFePO4 packs?

After seeing this thread on the Turnigy LiFes (http://www.rc-monster.com/forum/showthread.php?t=24416) I decided to get some.

Got four packs. I'd read that they needed to be "broken in" (mentioned both here and on the Amain web site). So before use each pack was given 15 cycles of about 1C charge (5 amps) and 4.5C (20 amp) discharge to a 50% discharge depth (take about 2500 mAHr out). Packs never even got warm during this process. Then I used them for racing 1/10th scale stadium truck with brushed motor. Never ran close to dumping them (more like used about 1/3 capacity). Never charged at more than 2C (9 amps) once they were "broken in".

Raced about 10 races this year and all my LiFe packs are puffed. They didn't puff during racing but in the two week interval between races sitting at about 50% charge. Actually, I only used two packs regularly, but even the ones barely used are puffed from sitting around.

I remember when MaxAmps announced their "Green Series" posters on RadioControl Zone lambasted them for their pricing, comparing them to the Turnigy packs. MaxAmps response was that the Turnigy packs were low quality seconds, which brought further booing and hissing at MaxAmps.

Maybe the MaxAmps guys were right. Seems a number of other posters here also have these packs puff.

So what do I do with my puffed Turnigy LiFe packs?
