The crazy stuff you've seen on Twitter thread

See stuff like this all the time, just never captured on video. That is a great video of what a small lithium-ion battery can do when it goes into thermal runaway.
I hit one of my solar landscape lights with my mower and the battery burned from exposure to air. It was a small battery and done by the time I was finished mowing. I tossed it a week later to be sure.
A house down the street burned when the guy's model plane Lithium-ion battery charger bank caught on fire. He had multiple planes and batteries. It burned worse than a gas fire. The fire drpartment is just down the street and was there in 5 min or so, but couldn't get it to stop burning. It didn't totally burn, but it took a year to fix the damage.
I've thought about a solar system with backup batteries, but I don't know where to put them. The basement or garage seems risky. An outdoor enclosure seems expensive.
There is zero ways to suppress a lithium-ion fire. They are an oxidizer, meaning they will produce their own oxygen. I've seen Tesla's put into pits of water when they were burning and they continued to burn for days. My job, we do detection and controls for lithium-ion battery manufacturing and ESS systems. Normally we pick the off-gas up well before a thermal runaway event. Once a battery starts off-gassing, thermal runaway is not too far behind. The gas is highly explosive. If you want a quick read on what lithium-ion batteries are capable of, do a quick Google search for "Surprise, AZ lithium-ion".
The Jeep 4Xe's are even known for doing a lot of damage with their small battery. That is 1 battery pack. Now imaging 100 of that size packs in a shipping container.
Everyone thinks this is smoke from a fire, and even the firefighters in that video are treating it like it without visible flame. However, that is the explosive (and toxic) off-gassing from the battery.
IF you are going solar and are putting in batteries, Tesla is the way to go for batteries. They have one of the best records for safety with their BMS systems. The basement is a no-go for batteries per building codes. Your best bet is the garage or outdoors. Tesla batteries are rated to be outside, depending on the climate where you are.
I rent a seasonal campsite and use something like this to store my lawn chairs and lawn mower.

My campsite is in the flood plain, and things have to be moved out at the end of every season. I mounted my shed to a piece of plywood, and mounted 4x4 skids to the plywood. At the end of the year, I drag my shed/skid onto my utility trailer and drive it home, 5 miles away.
