It sure does risk an explosion. Watch this other video where the ammo container reached 700 C (1300 F). And in this video the testers pulled the can gasket off before the test to avoid a gas buildup and explosion. It's pretty clear that a catastrophic failure is likely -- mind that the tests in both videos are with a fraction of the amount of Li-Ion than you would find in an average 5- or 6- amp Dewalt battery.
Bigger Li-Ion batteries have been known to cause a deflagration; one of those badly injured four firefighters about 3 years ago.
So you believe every random person you see on youtube? I doesn't appear likely at all that the ammo can is going to catastrophically explode.
Remove the gaskets or let them blow out the corners, they are not that substantial.
1300 degrees steel glows dark red in sunlight. Do you actually believe him on that? Looks like the paint on the outside paint is still intact to me. All the other test I have seen have 200-250 degree outside temps of the can. I don't know why he said it but its BS.
Many RC 3S battery packs are 5200, 6500, or even 9600 mah or 5.2, 6.5, or 9.6 amp hours. Only my tiniest of planes are 3300mah batteries. Some RC batteries have upwards of 100C discharge rates even 130C compared to a very mudane 3.75C discharge rate for 21700 cell that the High output power tool packs use.
In other words a 3S (3 cell) rc battery is going to have 3 really big bangs that the ammo still contained vs a 2P 6.0 HO pack 10 much smaller pressure spikes as each of the smaller 10 cells explodes in chain reaction.
