Default spontaneous lipo combustion?

Id like to know if anyone has ever had one, or directly know someone who has. I dont mean under load or from damage.. i mean a healthy lipo, either charged or not, just spontaneously bursting into flames..

This has been asked/discussed/argued a million times over. The short answer is yes. The longer answer is do a search and you will find more than you can read on this!!!

Unprovoked, spontaneous lipo fires? Yep, not that uncommon. Here is one story:

Here's a post where a lipo went off on public transportation:

I know this wasn't your question but here's a gruesome "while charging" fire that made a real impression on me:

I don't believe that they go off unless they are shorted out. The first one you linked to was "thought to be an electrical short", the second was probably punctured in transit, the third was over-charged.

So I don't think they go off spontaneously, no. They need a short - and a big short, one that doesn't melt instantly. Or they need big damage by something that can short them.

I don't believe they spontaneously combust. If they did, we would have heard about the hobby store or Chinese lipo warehouse that was destroyed in a violent lipo fire. Say what you will, but I believe behind every lipo fire is a human that made a mistake. Whether it is running or charging a crashed pack, over charging, shorting, whatever. I can't even get the damn things to catch fire when I deliberately try, so I remain skeptical.

Never heard about a battery just go off on fire. All examples I heard off (incl. the provided links here) are either caused by a battery involved in a crash, punctured/shortened in any way or charged wrong.
Regardless I try to keep some measure in a way that I:
- do store my batteries in metal boxes as well as special fireproof boxes or LiPo sacks
- charge them in LiPo sacks only
- keep an eye on batteries involved in a crash and keep those away from the rest for quite some time.

Yeah I guess this post came off as another "lipo fire" thread but it wasnt at all.. I really havent been able to find a single verifiable story of one just going off unprovoked and years of keeping them like hand grenades and locked up in fireboxes got me searching.. but i suppose its just a handed down fear, and i guess if i start leave them out, with my luck, id be the first to have a report of his place burning down.. HA!! guess its superstition at this point..
