A battery fire just has to burn itself out and that happens when the energy it contains is gone. The new thinking on EV fires is to pick them up and dump them into a frac tank full of water and leave it there for days.
The halon and CO2 systems I used to install dumped in maybe 30 seconds.
“The halon and CO2 systems I used to install dumped in maybe 30 seconds.”
Does that mean a larger halon system would work? Or not at all?
