What extinguisher for LiPo Batterys?

[DasDouble]

Hello World, my 1.185Wh batterypack LiPo Pack did just arrived. Now... Im scared^^ So Ive asked myself: What will I do when the shit goes off? Well, I thought, throw the stuff out of your window and hope you throw it not on your wood-roof garden rather the garden of your neigbour with all the vegetables inside^^ But seriously:

I thought about an extinguisher. What brand? A, B, C? Co2? What do you recommend? I know the idea with this sandback.. But this doesnt help me a lot, when the shit went already off and my room is burning.

-Cheers, Elias

are you scared ???
when my lithium ion pack brant, ask me the fire department what exactly is burning.....

and then that was a special mix, because after the brant even stainless steel began to rust....special extinguishing agent with acid.

unattended Charge the Battery...

A class D extinguisher specific to lithium I believe is the only sure bet but they cost a fortune. Any dry chemical extinguisher can be used to contain the fire and stop it spreading. The actual pack will burn out quite quickly while you are carrying out the containment. Never ever use water as that will actually feed the fire. And yes, the fumes are very toxic. Any metal the smoke reaches will probably rust. Wonderful things are LiPos.

So... sand?

Pretty much, nothing puts it out. Regular extinguisher will work for putting out the stuff you shouldn't have had so close to the bike/battery. If you are standing right there staring at it that is, when it starts.

My personal plan, batteries are stored in my fireplace, and a flat shovel is very close by, and a door to outside is right by the fireplace. Smoke alarms right there too.

Paraniod? Yeah maybe. I don't put cheaply made Lithium Cobalt batteries on charge and go to sleep, that's for sure. I don't worry near as much about Lithium manganese or Lifepo4 packs.

If shit happens, I might be able to grab the shovel, and flip the damn thing into the yard. If it's at 500F or more, I sure couldn't do that with a pair of gloves. I've had my face burned off before ( only 2nd degree), so not looking to repeat it.

 

[dogman dan]

Oh, yeah, sand. Just have about 500 pounds of it handy.

I have asked a firefighter via telephone. He said Co2 Extinguisher are working... I think I will buy one from Amazon. Weights 8kilogramm.. A bit too much to carry it around with me on my bike. But maybe a Fire-fight-spray would do it...? xD

Rechargeable lithium-ion batteries contain no metallic lithium. It is burning solvent and plastic - extinguish accordingly.

 

[dogman dan]

Yes, and just as hard to extinguish, as a burning quart of solvent, paint thinner, gas, etc.

My point is, a typical home owners extinguisher good for a small kitchen fire won't cut it. You'll need a larger one for a good size lithium battery going crazy on you.

Get the damn thing out the door, then use your extinguisher to try to save the house.

Lipo-Safe Bags

Here ... http://www.hobbyking.com/hobbyking/store/__1114__85__Batteries_Accessories-Lipo_Safe_Bags.html

one person on the comment section of the large bag page said : the stitching is not that good , it is better to just charge your lipo battery in a large ceramic flower pot . ( interesting , I would like some opinions on that since, of the surface it sounds like the bag would work )

But then another person said he did a test and found that the bags work .

Perhaps charge lipo's in a Ceramic Flower Pot, that is also put inside a larger Ceramic Flower Pot . ? or charge in the bag that then is put into a ceramic flower pot .

Perhaps even better , between the two ceramic flower pots have enough space to put at least 10mm or more of sand ?
and charge out on the patio / balcony , next to a window .

Thank you for this tip. My 1.1kWh Pack is originally in the box.. -Under my bed lol. But next to a window and ready to be thrown out Im asking for this because my Lipos will be mounted in my Vector Frame. And I want to be able to delete the fire when the whole stuff is going to go off..

I've contacted couple company about Class D extinguisher ( made for lithium and other reactive metals.

Price is about 950$ CAD !! and only come in 30 pounds format! I still have two class A B and C but i feel that it would be very usefull in case of bad luck.

Please let's find together great places where they sell these at more accessible price!!

Do we need to if there's no reactive lithium fella? Unsure.

Smothering does sound like a good option where able.

You don't need a class D fire extinguisher, as there isn't enough lithium in a lithium ebike battery to make an ear ring.
What burns is the plastics and organic solvents. It's the gas produced in the thermal runaway that is the real danger.
Flammable gas needs a class C, CO2 extinguisher.

Lipo bags do next to nothing for a battery the size of what an ebike needs. for a little 3s 800mAh battery, they are OK. for a real battery, they are just going to collect more gas in a concentrated area before they explode.

Lots of water...get them in a waste bin full if you can move them, or just dump it on them if not.
Soaking wet towels, or fire blanket, etc etc..anything to quench the heat and keep the oxegen out.

Mineral oil works best!

and its way cheaper..

however nobody wants there pack in oil i guess

see my yt videos of exploding lipos in mineral oil!

These really aren't unique in the hazard they pose in todays households. I store and treat them with the same care and respect I gave to black powder (low explosive) and smokeless propellants (a similar "runaway' hazards of munition reloaders when I had such stuff around). Proper storage, containment, AND work areas are essential ("it's a solid steel reloaders workbench! What could go wrong?!?" uhhh,... ya, about that.) too, as well as safe installation considerations.

I recently found an old cell phone battery that had been lost in boxes of storage for a couple years. It was pretty swelled up and kinda startling from various environments of extreme heat and cold. But was still safely wrapped and secured in the "altoids" tin and metal box with other stored old phones.

I constantly harp on my daughters, grandkids, teens and others who carelessly store batteries OF ALL TYPES as well as other hazardous items in the home. They WILL cause damage to anything nearby, and the possibility of anything worse DOES exist!!! Many have never had problem with lead/acid batteries,.... but I've handled THOUSANDS! And have seen more than jus a few violently explode!!!! Out the many 18650's you may see and handle,... you too will eventually see one go bad. Better to expect it than to be tragically surprised!!! And quit being so careless with the other batteries in your home, shop and garage!!! They have a tragic potential too!!!
