How to build fire protective battery charger enclosure? - eviltoast

In the last couple of years, I replaced all my lawn care equipment with battery powered and it has worked fantastically. I’m sure there will soon be other large batteries that need to be charged.

However I also note headlines about fires from cheap or damaged batteries. I don’t buy cheap and I do take care of my stuff so I’m not too worried but wonder if it would be worth building some sort of battery charging enclosure. Does anyone have any links, ideas or references?

My first thought is I have an unfinished basement with concrete walls and floor so that should be fire resistant: could it be as simple as stacking cinder blocks or pavers? My second thought is that would make a great oven, so no. So is there something I can do for my chargers to protect my house from any chance of fire?

    Y’know - I think stacking cinder blocks and some pavers on top would actually work just fine. Just angle the cinder blocks so the ones at the bottom have the holes poking out (and into the enclosure) and that should provide enough airflow to keep it from getting too hot in there.

    Heck, you could probably angle them all that way except for the top ones. I haven’t seen videos of battery fires, but unless they’re like really really flammable, the fire shouldn’t burn out from around the several inches of concrete that surrounds it.

    Remember fire burns up so the pavers and concrete blocks at the top will be what are actually blocking the most.

      Yeah, maybe I’ll do this …. And hope to never find out if it works. This would be really cheap insurance
