> place a giant bucket of dry sand above the pack, with the bottom layer being made of acrylic or other plastic that melts.
Honest question: is this a real hack that people do in these situations or did you just come up with it?
It's a hack I started doing after a friend's home almost burned down from a vape battery gone bad.
In any case, dry sand is one of the methods firefighters use to put out battery fires, the other being dumping it in a giant vat of water (that's what's done for electric cars) or class D fire extinguishers which are extremely fine powdered salt.
Acrylic is itself flammable, massive amounts of sand would be required to fully submerge and cool all cells (and therefore hefty acrylic sheets less likely to give), and it's likely that the sand will not spill correctly and evenly.
Please only use properly designed and tested fire suppression systems, as hack jobs might not help at all and do harm from the false sense of security leading to lack of actually effective mitigations.
So I need a suppression system to charge my phone now?
