DaveyBoyzToyz fun run at the Babylon town park yesterday. Damn Lipos...and the mighty effort to save a gorgeous Chris Craft Corvette. 🙄😬😪

What to Do?
At the moment I have put the LiPo into a “LiPo Safe Bag” while I give the situation a little more thought.
Like Chris’s LiPo, this battery may have been a little bloated when I bought it from new - it certainly wouldn’t be the first or the only one - but I do think that this one is a little worse now.
I am not sure how to check the internal resistance or know what is an acceptable reading, but I would like to find out both.
As far as disposing of a LiPo is concerned, back when we were first using much larger LiPo packs for large r/c helicopters and large 1/5 scale racing cars, we were advised of a method to dispose of them that worked and made them safe .
The method was to place the LiPo in a bucket of salt water and leave it for 24 hours (or longer). This had the affect of completely draining it and leaving it “inert” and safe to dispose of.
That was a long time ago. If anyone has any other more up to date method of rendering a LiPo “safe” before disposing of it, I would like to know about it please.
Bob.

Hi Gang...
Truth be told, as much as I like the high speed and high output I am not too thrilled with Lipos as It seems you need a phd to fully understand them. I don't like the small margin for error in charging and discharging them either. But I do know that a bloated battery is a battery that has gone bad and can be a huge problem.
I don't mean to run around like the sky is falling, but I found this particular article helpful. 👍

Man, I would. I put it in my neighbor’s yard to charge! Not really as this is, as Jump states a SERIOUS problem! Get rid of it ASAP. (Not sure how one does that).The bloating is caused by one or more of the cells outgassing. Quite probably a prediction of a boom & or a fire.

Imho. Stop the charge asap. A bloated lipo is a lipo to be disposed of. There is some sort of chemical breakdown occurring during use. The trapped gas in the bloat is a fire hazard. Get rid of it.

My 3S looks a bit bloated as well but it could be that it was always like that but I can't remember. But like you it has only ever been charged and storage charged using a smart/intelligent charger. One thing I did read about awhile ago is checking the internal resistance of the battery which I was able to do using my charger and it was within acceptable limits, so I will do that again. What is recommended is that you do this when the battery is new as a reference point, which I will do with any new batteries I get.

Scratch building 7 Faireys at a scale of 1:12 and also have 2 built by Dave Milbourn
As my Remora was charging around the lake today, I happened to comment to my friend Adam (who was with me making the short video of the Kopy Kommander for Boatshed) that I didn’t think the boat was revving as hard as usual.
He laughed as the boat is a superb performer, but when it came back to shore the LiPo was bloated as the heat shrink cover had ballooned slightly.
I have just put this LiPo on a balance charge and noted that all three cells are showing a very similar cell voltage with a 51% fuel available. (see charger port A).
…..suggesting that the battery is OK ?.
I always put a small strip of masking tape on each of my LiPo batteries and add a mark after each charge - just so I know get many times the battery has been charged.
It is worth noting (when counting these “five bar gates”) that this battery had only been charged 8 times from new, and every charge has been a balance charge on this RC-DC100 charger, so it has not been abused in any way.
I am charging it outside on the stone paving - just to be safe………..
