If I don’t get an answer to a simple question, I do.
Also stop spreading misinformation. There is no need to supply air to sustain a lithium fire.
The batteries most of us use are lithium cobalt oxide, the oxygen is supplied by the lithium cobalt oxide (which means it has oxygen) cathode.
So no amount of air sealing will prevent a LixCoO2 battery fire.
I am done wasting any more time.
To everyone else, instead of listening to random people in the forums , do your own research.
If you can’t source extover try to search for Poraver expanded glas, it’s exactly the same stuff (both from Dennert actually).
Poraver (or expanded glas in general) is the type or better brand that is used as a filler material in dry mortar formulations, like light wall mortar and plasters (for extra insulating properties and higher productivity per weight ratios).
Products with similar properties that are used in such building materials are fumed silica and perlites or expanded vermiculite minerals (all of them are absolutly non flamable and can be used as a fire prohibitive/suffocating agents), expanded glas is preferable as an extinguisher for it’s easy free flow characteristics, the somewhat easy to work with density while not being to light (like fumed silica).
I literally sit on a few cubic meter of that stuff at work
I work for a German dry morta and construction chemical producer. I’m a building material tester and development technician, so I do mostly “dirty” labwork formulating/testing new products or test what kind of materials different suppliers have to offer.
We mostly use expanded glas in smaller sizes (Extover is abaout 1-4 mm in diameter) but I don’t see why a smaller size shouldn’t work to extinguish a fire. The heatsource for that stuff needs to be submerged in that stuff btw so an openly burning fire needs quite a heap of that stuff.
You literally can not put out a lithium fire. You can’t. Fire departments can’t. When Richard Hammond drove a Rimac concept one into the swiss hillside it burned for 2 weeks.
Maybe if you attach a trailer and tow a fully equipped appliance behind your board then maybe you would be fine. Lets talk to someone who actually has burned his board to ashes?
@Andy87 educate the person please.
No cool you got it. You tow a fire appliance and a tank full of the correct retardant.
Awesome.
Talking of retardant? I think you think we are all a bit retardant. Or is it retarded?
English is such a duplicitous language.
I’m dying laughing
I hate that we still don’t know who this gamer child is
I know exactly who it is. You just need to have some history is all.
I am going to let you keep on because we all like a bit of drama.
whose the new profile pic of
Yep, you basicly just contain and cool it down as best as you can till the batteries lost it’s charge.
Burning hybrid cars for example get just dumped in a container with water after the visable flames are dealt with … or they just burn down to crums right from the start.
And there was me thinking you wanted to have a beer? Act like a child mate and you aren’t going to be able to hang with the grown ups. Just concentrate on your family brother and leave this place alone. I know its you so let it go now.
do we get to know who you are referring to?
Yeah, good point. I will definitely use NESE for my next pack. Should be bulletproof as far as abrasion resistance is concerned.
I’m thinking if using MIDI fuses for all serial connections would be a good idea? If one with the same hole pattern as the NESE serial bus bar could be found, it could essentially be a drop in replacement. Would reduce the risk of a short.
@Andy87, could you please share the story? What happened? How did you manage to handle it? Do you have any recommendations for dealing with the situation? What kind of equipment would it be good to have for dealing with the fire? Fire extinguisher? Fire blanket?
Please stop trolling these threads.
I did short a fully charged 11s4p pack because I was young and stupid and not concentrated after work…
First thing I would say to take care of is never work on batteries or your board wiring in general if you do not have enough time. The I can fast try this and that mentality just leads to unnecessary faults.
Second thing I would recommend is to be prepared for the worst always.
I think in your case it was the same. From the first sparking noice till the fire is in full action there is not much time. So for all who think they can just through a pack on fire out of the window, you won’t do that.
I was more or less lucky, the board was laying with the deck first on an ikea carpet. The trampa deck took away already a lot of the flames and I don’t know what kind of material the carpet was, but it just melded and didn’t got on fire.
I first threw a fire blanket on top, than used a fire extinguisher and in the end poured 5L of salt water on it.
I could get the flames a bit under control with the fire extinguisher, but it wasn’t enough to fully put out the fire. It just started to burn again and again.
If to look back I was kind a stupid to run back inside the flat again and again to put out the fire. The smoke was so strong that I couldn’t breath and once was close to fall down.
I managed to put the fire out before the fire fighters arrived thou.
Best is really to have a place where a pack on fire could burn out without to put anything around on fire.
Even better would be to have it in a room where the door is closed. The dust from the burning cells just goes everywhere.
We did a complete flat cleaning including walls etc. twice or three times and still there was black dust the next time we cleaned.
I think it tool 3 month till the smell totally went out of the flat. Good that it was summer and we could let the windows open and good that directly after that we had a 3 weeks vacation where the windows have been open all the time.
In the end we went away with „just“ this
And some melt rubber on the walls here and there.

Also during the fire some cells exploded from time to time and hurled some meld rubber through the room. Very happy that nothing of that hit me while trying to put the fire out.
So ja, a save place to just let it burn out or as minimum fire blankets and gallons of salt water. I think a big bag of sand will help too, but you need a not of it. Not just 5kg. That will just be blown away within some seconds.
Sounds like a scary experience dude. Glad you got off relatively easy in the end.
Could have been a lot worse.
Oh man… so what do people do that have a small apartment and no real storage space or any possibility to put a big metal box anywhere safe ?
Just live with the risk ?
A Fire detector would help at least to know when someone is going down - thing is I am sometimes overseas for weeks or months with my apartment unattended.
Any ideas ?
Definitely way worth. The fire was close to our couch. If that one would have started to burn there wouldn’t be much I could do. Same for the carpet and we can be lucky to have roughly 5m high rooms too.
Store your packs with low voltage but make sure there is nothing connected that can drain the pack into over discharge.
The less voltage the less energy inside of your pack.
Top mount batteries can fit in smaller metal boxes, or you can build a small bunker with stones for example. For enclosures it as well reduce the size if you do remove it from the deck.
I think the risk that a battery just sitting around start to go up in flames is very low, but while charging or moving around the risk rise up.
Maybe you do not have space for a big box, but you could cover a corner in your flat with dry wall and move away any other stuff close to it for to charge and store your board. That’s already better than nothing.
