Ammo can storage

I use a 81mm mortar ammo can, was like $30 to my door from Amazon. Will easily hold 3 full size batteries with room to spare. I lined it with fire insulating blanket. It should contain a mishap if a battery goes south on me, or at least minimize the damage. I keep batteries and charge inside the house.

I've been eyeing a fire resistant cabinet like the one you show above. I'm going to have to re arrange my garage
I forgot to add details. I actually looked for a cabinet for nearly 3 months. Zoro had a sale AND free shipping. I was shocked by the deal and jumped on it. Listed now for $508.87 plus shipping. I paid $270 shipped. Which was $100 less than what i saw used being sold for. Seemed to good to be true but sure enough free shipping too. I have seen them for $400 shipped, using Google search tools i got at leadt one listing a day until zoro popped up

I tried repurposing an ammo can for storage too, but ended up switching to Home Safes for better security and peace of mind. The seal was solid on the can, but I worried about moisture over time. With Home Safes, I added some silica packs inside and haven’t had issues since. Plus, locking it feels more reliable than just clamping the lid shut on the ammo can.

The R/C guys use ammo cans to charge and store their hI-discharge batteries for helicopters. You’ll need to remove the seal so it will vent in case of a fire. They also use cement blocks and stepping stones to form a bunker. They are real cheap at Home Depot.
 
Newb ebike dude here. I have a couple of 13ah lithium batteries to maintain on my new bike. My garage is very hot in the summer and very cold in the winter. Not the best place to charge or stow batteries. Which leaves me to my radio room where all my electronics and radio (ham) stuff is. I have a large ammo can, and is it safe to store and or charge a battery in this? I don't really have another choice. Is storring a battery inside your home safe.
Another possibility; I am using an old cast iron woodstove (much larger inside than my ammo can) vented through a non used chimney to store batteries, and I charge outside or on a stone floored foyer with no living space above.

The cement block idea sounds inexpensive and easy to me, thinking of off season storage in my home. Would an encasement of cinderblocks (one thick) contain a runaway bike battery fire? Would the heat still be a potential fire hazard in my basement (on a cement floor but with wooden joists and flooring seven feet above it)?
 
Welcome to the forum and yes, an e-bike lithium battery fire on a concrete floor WILL spread upward to a 7' ceiling! Luckily, such fires are rare if you buy quality batteries and use proper charging procedures. Specifically, do not charge them while unattended.

Ammo cans are a deterrent at best, and will not completely contain a fire. They can buy you time however to move the burning battery outside. I have my ammo cans mounted on a dolly that can be quickly pushed out of my garage with a long handled rake at the first sign of trouble.

I also have a smoke detector located above the charging location.

Other safe charging / storage locations are an unused fireplace or wood stove. Cinder block encasement would also provide some protection but may not be enough to prevent a fire from spreading.

Again, welcome aboard, and by all means, feel free to ask more specific questions. 👍

The cement bunker is going to be the best and cheapest way to contain a battery fire. It will naturally vent because the blocks don’t fit airtight next to each other. Fit them together so one layer of hollow block keeps the battery off the ground and you will be good.
You will have to deal with the toxic smoke if your battery pops off, but nothing will be burned or catch fire.
