What to do with my puffed Turnigy LiFePO4 packs?

[What's_nitro?]

By "puffed", do you mean pressurized, or just a little squishy? I have a few older LiPo packs that are a bit squishy and still run fine. Have you run them through a 1C cycle since they puffed to see where they stand?

Definitely pressurized. They are more like "rolly polly" than a little squishy. One of the idle ones feels a little soft but the other three are 1.2 inches thick in the center while the least puffed of the bunch measures 1.03 at the end of the pack where it is least puffed. So the really puffed ones are almost 20% bigger in the center.

I have not tried cycling them. But they won't fit in my car any more as is.

I guess when I made the original post I was wondering if someone was going to suggest sticking them with a pin to let the gas out and sealing them again with duct tape.

LiFes are not supposed to be dangerous when punctured, right?

I checked the discussion section on these at hobby city and a bunch of people have these puffed for no apparent reason.

Yeah, I'd call that puffed.

I'm pretty sure they still release hydrogen when they "puff" so I wouldn't recommend puncturing them.

I have an "H-bomb" in my cellar?

So what do I do with them?
