While very interesting, that seems like it would be one hell of a fire hazard as well. Especially for the ones that are tightly packed in the middle of each bundle.

Yeah, my first thought on reading the article was that it didn’t detail his fire control systems..

That's the neat part about lithium fires you just can't, they're self oxidizing so there's not much you can do to definitively put them out the best option is usually to flood them with water to cool them down and contain the damage they cause.

Yeah. Commercial home solar battery power as I understand is done with safer chemistries, such as lithium iron phosphate, which while they have a lower energy density (which is not a big downside for a stationary building) don't have the thermal runaway issues that labtop lithium ion batteries have. I wouldn't want to live next door to the DIY labtop battery array enthusiast.

He seems to be doing it fairly safely by having it housed in a building a whole 50m away from the main dwelling. A fire from there could spread to the house or elsewhere but it's no longer a metal fire so it's a lot easier to deal with and just contain the fire in/around the shed. I'd probably add a nice gravel buffer around it to help that and live in a reasonably well hydrated part of the country so there's not as big a fire risk from embers.

Great if you are a skilled electrical engineer who owns a bunch of land somewhere that doesn't have any fire risk.
