Default Battery Issue

I have two recently purchased 2c Lipo 5700 25C soft Onyx packs and after two uses they seem to be holding air. The packs have "puffed" up and feel like a balloon. I was told that was an indicator they were ready to go but they are only 3 months old and have not been beaten up.

Are they still OK to use or ready to go up in flames?

Put up some pictures if you can. I guess it depends how "puffed" they are. Some people continue to use them for a while if they're slightly puffed, but if they're massive, try warranty or get rid of them.

Get rid of them as soon as possible. Anyone telling you to run puffed lipos is nuts.

We also need to know your usage habits. What vehicle, esc, motor, charger? Were they stored charged or discharged, what voltage?

Do you use a battery charger with a lipo charging program?

Do you charge at the safe charge rate for your battery?

Do you have LVC set on your ESC?

I have an Onyx 230 charger and run the exact specs the instructions states...
I charge on the Lipo setting for 2c at 5.5A.
The charger is a auto charger the same brand as the batteries.
The batteries are soft sided (not the hard packs) much like the old NIMH packs, if that makes a difference.

I never thought anything of it due to a change in Temp and they puffed up a bit shortly after I got them.
