Does the bag have an opening for a power cord? If not how do you charge in the bag? Is it transparent? If not how do I know when charging is complete?
I have watched YouTube videos on the topic of thesr bags, including them containing liion fires. They work.
My bag only lasted until I took a blow torch to it.... While they obviously work, i noted the outside is very flammable plastic, and the fiberglass empirically is only cigarette lighter proof and not blow torch proof. Fiber glass can be made blow torch proof, by adding borax to silicone caulking. Tubed silicone caulking, alas, if very flammable, until the borates are added. For more money, you can order flame proof caulking. I tested my borated caulk on aluminum and fiberglass with plumber blowtorch (butane). The insulating, borates add much resistance. Catalyzed silicone with borax should do even better, I assume. Test your mixture first.
If the standard charge bag's fiberglass were borax and silicone reinforced, and outside not flammable, I. Would feel better about them.
I still have my bag, in which, put spare 18650s (in protecting plastic carriers). But my bag now has a hole which I poked through in under a second with my blow torch. (Adding the above borated barrier probably adds 30 to 60 second, or more resistance to a direct blowtorch.)
Jet engine technology heat reinforcement on light metals that would otherwise melt, those material engineers have really cracked the problem. Why they dont apply that technology to the cargo area, then to isolate declared liions from the rest of cargo, and separate cells from each other, is beyond me.
Nevertheless, despite my personal bag design resignations, the youtube videos demonstrate them working, by real users.
There is the direct short=roman candle failure-the worst does not seem to last more than 40 seconds . Which would have one temperature.
Then there is the overcharge explosion. The temperature and physical damage result would different.
I would only go imr if they came witb over charge and under charge circuit which would drop the short protection. Relying solely on charger circuit is stupid. Triple redundancy in life. My third is cookie tin. Forth watch and testing voltage off charger to make sure the electronics are in order. So, 5 layers of protection when charging. 1. Name brand. 2. Protection circuit 3. Smart charger. 4. Cookie tin 5. Always check voltages. 6. Set timer then, you could: charge only in middle of your empty garage. 7. Fire proof garage. 8 install a fire alarm near charging area. 9. Gfci charging outlets and keep lots of ice water to cool the lithium fires 10. some F500 or metal fire class extinguisher 11. Move next door to the fire department 12. Go back to nimh, despite their inferior capacity and higher ownership cost 13. Discard nimh cause they can short too and cause fires 14. Discard your candles because fire causes fire 15. Just wear an eye patch, to let one eye be ready for the night... I am joking, but incorporate as many as are practical, if burning down your house matters.
I think the f500 can be purchased for $200 and added to water. The FAA airboyd has video how they use water on planes to put out laptop fires. F500 is utterly fascinating. If I could get it for $50, I would own some....
Fireade not sure if rated for lithium fires.
