Puffed LiPo = Dead LiPo?

[loa]

Hello,

Last time I bashed my revo with my LiPos, I noticed that they were a tad warmer than usual after the run. Never actually hot, but slightly warmer.

Today, after the run, they were trying to bend the aluminum box I had made to hold them. Puffed and burning hot. I could barely hold them in my hands.

They're now cooling in sand and my question is: are they completely dead?

If so I'm going to safely dispose of them.

Thanks

Loa
