e-Electric Batteries & Chargers > Puffy LiPo ?

Hi,

I acquired a number of LiPos recently, all of which I charged and put to one side (About 1 week ago) as I set about rebuilding a Heli.

Today I discover that one of the LiPo's has puffed up on the two outer sides - it's a 3-cell battery, so the 2 outer cells seem to be affected.

It feels like there is liquid under pressure under the outer skins, as you can squeeze it, but the pressure never dissapears - you just end up displacing the fluid end to end ??

Not so familiar with LiPo's, so looking for experienced comments as to what this is and is the battery safe to use or is it U/S and should I get it outside the house quick ?

Many Thanks
