LiPo batteries feel squishy


Hey all,
I have two "GE Power" 860 mah 7.4 volt packs that feel kinda squishy, like there's air under the red shrink wrapping. Is this normal? My stock battery that came with my UFLYS is not this way and neither is my "Blue" Lipo pack. I read that if LiPo's expand, that it's BAD - what ever that means. I just don't want to burn the house down. my wife would do bad things to me.

BTW, i wacked it hard into terra firma this AM after a gnat flew in my eye. Blades, flybar, one tail strut gone, maybe bent main shaft. was having fun too.

Really? it's not bulging or anything, just feel like there a small piece of foam under the shrink wrapping and the power is superb????

From what you say I don't think they are puffed up.. I wouldn't throw them away but I would keep a eye on them and store them in a safe place.. As you should do with all LiPo batteries..

thats starting to puff but I have seen worse - thing is with lipo's is that the material cannot be exposed to the air or they are a fire hazard - once they start to puff that airtight skin stretches and is more easily punctured.
there is a video somewhere where a guy gouged one with a nail on a stick and it just went up like the last video I showed you.

Its always worth asking but lipo's usually tend to puff if they have been abused so you may well get the question "what have you done to cause it"

Dunno, but I got them from WOW Hobbies.

I peeled back the red shrink-wrap label, and the little white tape that's under it, exposing the silver wrapping of the battery. it's definatly puffy under there. Tossing them, not gonna chance it.

Does anyone know how to properly dispose of LiPos?

Discharge them as low as you can then stick them in a bucket of salty water for a few days is the general practice.

I got this really cool RC car and in the first week of using it the battery puffed up! What a waste of $400!
