So to be clear here....if I have a 6S lipo that charges correct, right voltage, balances well, flies with the same power but is slightly, ever so slightly, swollen it's a potential fire hazard and could flame up just sitting in the metal tool box??? It needs to go to the grave yard before the reaper comes and lights it up for me??

I have 4-6S lipos that are a little puffed that I have been flying. I don't want to ditch a battery that still has life but I sure don't want to smoke my T500 or burn down my garage. What I'm understanding here is they're a serious fire hazard.

nickt919,

Serious fire hazard. There are several posts on forums here on RR that indicate so.

You can gamble if you like. I had puffed li-pos that I downgraded to drive non flying equipment and promptly them put back in the ammo can or bag and worked well for a year or two. Their 2nd life lived doing 1/2 to 1 C work.

Flying a pufffed pack again, I dont think so, unless the purpose is to do an unplanned pyrotechnic flight demo.

Slight Swelling......
nickt919,
Yours sounds like a bit of a different case... yours are still reading the proper voltage and taking a proper charge, so in your case, I would say that, NO, you do not have the same problem as the OP... my suggestion would be to take the slightly swollen pack and place it in your freezer over night... then take another look at it in the morning.... the "freezer trick" can help pull the swelling back in..... but as long as you are balancing properly and there is NO external damage to your packs, you should be safe.... but would tell you to keep an eye on them and in your metal tool box or some other type of safe container.... if the swelling continues to get worse and you find a weak cell, then by all means make that battery go away!!!!!

I would send it back to HobbyKing with a thank you for a POS note in the box and also say thanks for the 30 day warranty. It was real, it was fun, but it wasn't real fun.

I didn't intend to Hijack here but this battery condition is important to EVERYONE flying lipos. I just wanted to be very clear about what I was reading. Thanks....

My lipo puffing is probably my doings from unintentionally leaving them sit fully charged for too long but then I have a 2S Thunder Power RX lipo that has sat fully charged for months and its physical condition and performance is just like the day I got it. The HK batteries may not be the bargain they appear to be.

doorman,

I just read your "freezer trick". Does that really work. I understand my battery is Kaputt, but just for future reference. Knowing my luck, I would get "FREEZER BURN".

Freezer.......
I had a flying buddy tell me about this and I have used it a couple of times now and yes it does work.... but please do not mistake it for a reason not to be safe with these batteries... I have done it on ones that feel/look a bit puffed but were still reading and charging fine...
Bottom line is play it safe... if your not comfortable with this then by all means do dispose of your puffed batteries...
As far as the HK batteries go.. for the couple that I have had a problem with in the last four years, I would still consider them quite the bargin....

Good Luck....

Here's an incident with Curtis and a lipo....

http://www.allmyrc.com/forums/blogs...ve-4-27-11.html

The article goes on to read the lipo puffed and went into flames in his hand. He is not too explicit about the condition of the battery except that it was an old pack being balance charged.
Not the same condition of the OP's topic or my condition but it's all relevant......When do you take a lipo out of service? ...also, CORRECT storage, handling, and charging can not be over looked for one second.
