I drilled holes and lined the holes with rubber grommets for wire ports. I added ceramic fabric lining and mounted a smoke detector very close to my basement charging spot. I have welders gloves close by and NEVER charge unattended.
Less dangerous than a lithium fire. FFS!
Charging space: 9.5*6.5*14.5 inch / 240*165*380mm
I've been eyeing a fire resistant cabinet like the one you show above. I'm going to have to re arrange my garage storage to make room for it though. In the mean time, I'm using a pair of these $28, 20mm ammo cans to store & charge batteries.
Great idea. I just didn’t want to add 4 different connectors or redo my batteries connectors. Silly as it may seem, I have nearly every adapter for my Satiators.
There are videos. I think my newest mods with concrete board and ceramic insulation will be effective. I don’t charge more than one at a time.
I have 3 Satiators which all use the XLR connector. I also have most of the adapters. On one of the ammo cans, I use this bulkhead or panel adapter:
Thanks for the ammo can info. I have a couple Costco metal ammo cans but they are too small for some of my batteries. I wasn't aware of larger cans like for 20mm. Shipping was steep for the ebay cans you linked but I got a "grade 1" surplus can for $45 with free shipping on Amazon.I've been eyeing a fire resistant cabinet like the one you show above.

I store the cans on a concrete floor in a semi heated garage where the temps vary between 55 and 80 degrees. I also have a smoke/fire detector nearby and never charge unattended. When full with 4 batteries, the cans are too heavy to lift easily and I wouldn't try it anyway with one burning inside. I keep a rake handy which I can use to grab the handle of the can and drag it across the concrete floor and out of the garage should it become necessary.
Just how effective these ammo cans are at containing a battery fire is unknown. This isn't a perfect setup but I figure it will reduce my chances of serious damage should a catastrophic incident occur.
As always you're incredibly inventive and resourceful! Nice!
Often some of the guns and ammo websites do sales on large cans. With a little patience, $35-$45 will get a nice large can shipped. The only caveat is they may not have been rehabbed and look rough. I pictured two 20Ah triangles on my large can but i'd not ever charge that many cells at once!
The eBay vendor I linked also has a website. The ammo cans above are on sale for $25:

The 20mm ammo can on Amazon is advertised as "grade 1" which supposedly means "Grade 1 ammo cans will have little to no exterior surface rust or blemishes. Corrosion is very minor, and limited to the contact points or pivot points on the cans if any corrosion exists at all. The interior of the cans are also free of corrosion and the seals are in new condition". A review indicates his was in unused condition. $45 shipped from Amazon seller with free shipping (for a 20 pound can) sounds like an OK deal then. I'm just going to use it for storage and not for my Yamaha batteries. Just for the cheap batteries.
