Lipo safety.. I lost it all. Please read.

YEP I CAN RELATE i HAVE IT ALL IN A MOTOR HOME AND BUILD AND REPAIER DRONES HERE IN THE SOUTHWEST i HAD A FRIEND JUST THE OTHER DAY LOSE IT ALL TO FIRE , AND FIRE IS RUDE DAM ID LIKE TO HELP SHOE STRING LIVINING NOW DAYS EVERYTHING GOING UP EXCEPT MY SSC BUT THE DRONE BUSINESS JUST KEEPS ON GOING SO FAR

A bit confusing... To be clear, all DJI drones use lithium-ion chemistry batteries, and all are DJI's Intelligent Battery design with their well-tested, reliable BMS.

Except on a strictly pedantic level, this is false. DJI uses a mix of LiPo and Li-Ion batteries (the only Li-Ion battery I can think of offhand is the Avata). I mean, techincally LiPos are "lithium ion" batteries in the sense that they use lithium, but they are not the same as Li-Ion batteries.

Uhhh... Lipos are lithium ion batteries. I.e. "lithium ion chemistry", as I said. The manner in which they store and release energy by moving and storing lithium ions between anode and cathode are the same. So on a strictly pedantic level it's true.

Uhhh... that's exactly what I said. What you said is true strictly on a pedantic level.

But saying Li-Pos and Li-Ion batteries are the same is like saying toilet paper and copier paper are the same thing because they are both made out of cellulose fibers.

Thanks for that. A good combination of humor and vivid mental images.

I intend to appropriate it and use it frequently.

Thank you so much for sharing, so sorry for all your loss. Certainly a wakeup call for me.

@BobaFut, please look at your post #22 where you quoted me, said what you quoted was false. Explain precisely what in my text that you quoted is false.

@BobaFut, please look at your post #22 where you quoted me, said what you quoted was false. Explain precisely what in my text that you quoted is false.

Because your post implies, through a very narrow use of the term "li-ion" (you say: "all DJI drones use lithium-ion chemistry batteries") that all of DJI's batteries are Li-Ion batteries. But there is a distinct difference between lithium-ion batteries and lithium-polymer batteries (similar chemical processes involved but they are built completely different and have different power delivery characteristics), and DJI uses lithium polymer batteries on many (most?) of its drones. In the common usage of the terms Li-Ion and Li-Po, your post is not correct.

Hmmm... so are you saying Lithium Polymer batteries are not Lithium Ion chemistry? Please educate me as to what chemical process is occurring in a Lithium Polymer battery to store and release energy, and how it differs from a Li-ion battery. I thought it was the exact same chemical process taking place in both.

I'm sincerely very interested.

I tire of the pointless bickering, so I did the simple search for you.

The difference between lithium ion and lithium polymer batteries - Battery Power Tips

A lithium-ion polymer (LiPo) battery (also known as Li-poly, lithium-poly, PLiON, and other names) is a rechargeable Li-ion battery with a polymer electrolyte in the liquid electrolyte used in conventional Li-ion batteries.

Bickering is being told you're wrong, and defending your claim when you believe your correct?

Okay. I guess I was wrong for something it is believe I implied. What complete BS.

****.. Leave it to the goood old forums. I share a tragic event that happened to me and hoped to raise al little awareness or somehtng, and now my post is a argument over the differences in lithium battedies.... Awesome.

I found this company while attending the annual conference/meeting of NFPA (National Fire Protection Association) and they have some containment systems that look promising but are not cheap. This is not an endorsement, but just info sharing:

https://www.kulrtechnology.com/safe-case/

It appeared to be well constructed based on handling it on the exhibit floor at their booth, and the sleeve is capable of containing up to 300 watts at 100% state of charge. The other containers they offer increase in storage volume and capacity but correspondingly are priced higher.

I found them while looking for a solution to safely manage, transport, and store li battery components damaged in fires I investigate and need to retain as evidence. As you may know, even damaged cells can still release stranded energy, and any cell or battery module exposed to fire is suspect.

There is a great deal of research and development going on at the moment to better contain consumer grade and industrial sized LI components. modules and systems, including the development of standards to regulate their performance based on testing (e.g.: UL standards).

if cared for properly these batteries are pretty much safe but after 11 years with spark, mavics and inspire I dropped a inspire battery in cracked gravel and what i saw for 4 or 5 minutes was a wake up call each cell went with a white cloud one after the other till it burst into flames shooting flames about 2 ft almost disintegrated while I watched from the window. Glad I dropped outside swelling had started it was about 5 years old and I am guesssing 70 plus charges and exposed to heat in the car I did everything wrong and got lucky it was an incident outside.
