Safe Ebike Battery Charging/ Travel Storage

I have just developed/ fab'd these:

DM183, I'm glad you posted that. I've have my eBike batteries (three 48vdc 7.8 AH each) in a 20mm ammo can (it is the style of the 'normal' 30 & 50 cal cans only larger) and have wondered if I have a false security in that. Burning lithium batteries are way out of my lane, and knowing you are not only an all round smart guy, but have been on the forefront of this tech, so if your Jerry can wall thickness is adequate protection, then my ammo can thickness should be good also ? My concern has been if one or more of the batteries light off they will burn hot enough to just turn the ammo can into poor man's thermite and add to the blaze.

From my relatively immature perspective, the first question re "Lithium" batteries is to be more specific about the chemistry.
LiFePO4 is "safe" in comparison to most of the others. I would not charge any of the others unless it was within my sight.

Peter, so when not charging, (lithium-ion, made in China), is there a very low chance of them self-igniting into a conflagration burning/melting everything in their path ??
When I do charge them, it is outdoors away from everything (perhaps I am overly caution, due to watching too many EVs going up in flame videos on YouTube?)

That is my understanding, but all require to be treated with care. Note that "lithium-ion" covers about 6 quite different lithium chemistries. They are not all equal and LiFePO4 is the safest of all of them.
