@@swashbucklingadventures9929 It must be enough water. You need 0.6kWh to vaporize 1l of water. This is the energy of an e-Bike battery. Fire department also uses water. It is not possible to extinguish the fire, because the electrolyte contains oxygen, but you can cool it to 100°C which protects healthy cells against thermal runaway. If you use a small container, which isolates and concentrates heat, it will heat up and also healthy cells will burn.
Awesome. I recently got one of these boxes for my batteries and was curious to know how it would hold up. Would you suggest removing the seal? Thanks for the video!
Yes, it's important to remove the seal. If you don't, gas from a battery can build up pressure inside. Also, always keep the box on top of a fireproof surface and away from combustibles. That should keep you safe.
@@hazard-creative what about putting a fireproof surface on the bottom of the box? Use some silicone or screws to attach a fire resistant plate of (something?)
@@tungsten8290 I would not personally be comfortable leaving it on a combustible surface no matter that kind of bottom I put inside. Best to leave it somewhere that can't catch fire.
@@hazard-creative I hear you on that. Maybe a large metal cabinet that i can use just for model aircraft stuff. I'd rather not leave it in a box at the end of the driveway!
Keep in mind if this happens in your home and even if the fire is contained, if you have pets in the home the fumes may kill them. PLEASE....think of your pets too.
Good video! The write up said 5 racer batteries were in the ammo can. What size batteries specifically? Just bought some ammo cans myself and still figuring out what I want to do and how I will do it. Thank you
Would the best solution be to put the individual lipos in a lipo bag and then put them in the ammo can? Having loose lipos in there seems to create an issue where if one goes they all get damaged and a sealed lipo bag may help to save some of them.
Whether or not it would work would probably depend on the batteries and the quality of the LiPo bags. You're also going to incur considerable expense. And you have to ask yourself: if a fire does happen, is it likely that you will use the other batteries again even if they were individually bagged?
I was thinking more along the lines that one going off wouldn't cause a chain reaction if they were in separate bags. It's doubtful that you'd want to use any that were in the same container. That said, I picked up my ammo can yesterday and I'm ordering more lipo bags from Amazon "just in case". Are there any special considerations that need to be made for Nimh batteries?
Yes; the idea was to stress test the container so the batteries were provoked to fire by overcharging. A hole is drilled at the front of the box (bottom right) to allow charge leads to pass in, and the gasket seal was removed. removing the seal is very important! More detail is available in the linked article from the description.
I doubt it would ever send shrapnel flying in all directions like a grenade, but a jet of extremely hot gas is certainly possible. In a test by the Bat-safe producer, an ammo can gets bent out of shape from the pressure, then rolls about a foot away off of its fire-resistant base when the seal bursts. The seal fails to provide any benefit, so I don't know why anyone would want to risk the unpredictability. th-cam.com/video/K8MQCatbxSY/w-d-xo.html (0:34)

I've been considering putting a bag of sand taped to the inside lid so when a fire starts, the bag melts and sand drops onto fire. Thoughts?
Fantastic idea and probably a life saving one too! Well done
Genius!
You could use water bottles which melt in the fire. Should be more effective.

Might wanna read up on Lipo fires before applying water to them. Water, believe it or not, makes them more volatile.

thankyou very much for have done it for me! It is very interesting what could happend

Appreciate this test and you posting the video! Thanks.
Great video. Thanks. Going this route to house my lipos. Seal removed on concrete floor.
Test was very helpful. Thanks!
I'd be curious to see the same test with a sealed box :)
me too!
Its all over youtube.. DONT DO IT! You create a damn bomb lol.
boom
@@badlilstang I want to see it 😂

Thank you
It was a mix of 3S and 4S, roughly 1 to 2Ah.
@@hazard-creative thanks for your reply and detail of what batteries were used. It's much appreciated!
@@hazard-creative so next to nothing. E bike batteries like mine are 380wh. Need to think of something to store it in
How is the lipo charging while it's closed?
I wonder what the bases temp would be worth a single for brick on the bottom inside of the can.
Have you removed the rubber sealing or left it as it is original?
What do you think would happen with 10 lipos in there??
Did you drill any additional holes or just removed the seal from the box?
There was a small hole added near the bottom for the charge leads. You can see smoke coming out of it early on.
@@hazard-creative small hole in addition to removing the seal?

What if i put each lipo in a zippy bag and fill the box with sand? For storage not charging. You think that would help
Put some water bottles, made from PET into the box. These should melt when the fire starts and drown the battery.
Great test
When the battery caught fire were you charging them? If so, how? Did you modify the box to allow a cord to pass through?
Yes; the idea was to stress test the container so the batteries were provoked to fire by overcharging. A hole is drilled at the front of the box (bottom right) to allow charge leads to pass in, and the gasket seal was removed. removing the seal is very important! More detail is available in the linked article from the description.
Michael Niggel did you use anything like silicone to seal up the hole to keep the fire inside? I'd like to use one of these for charging my lipos.
@@mikesstickers Not for this test. You can see smoke escaping from the charging hole at 0:10 and again at 0:20.
Was the gasket removed?
Roger Banks Yes. We also drilled a hole at the bottom for the charge cable. It's really dangerous to use a completely sealed box.

Mind if I ask what is the voltage of your battery and capacity?
The box contained a variety of batteries, mostly 3S and 4S between 1000 and 2000mAh.
Great video 👍👍👍
You removed the rubber sealing in the box?
Yes. Always remove the gasket before putting a battery inside one of these.
