With extinguishers size does matter, and multiple ones. Especially if you live rural and not in town with a paid FD.
Lithium ion battery explosion in my garage.

While on the topic, the first part of the cost increase of house insurance is the increase in price that is linear with the replacement cost, then there are the increases due to the perceived increases in claims due to environmental issues such as forest fires, flooding etc, then any new risks such as lithium batteries, drone collisions, or anything else the companies come up with.

Because it did. The scooter exploded.
Because people ride them hard, which heats up the battery. Then they plug it in to recharge after the ride (instead of letting the battery cool off first).

I think his battery just had it. It had not been ridden in quit some time.
The energy density of lithium cells makes a lot of modern life possible, but it also carries a higher level of risk.
Molicel suffered a fire at one of their plants last month, whose production included cells for automotive, aircraft, and other high-end applications. Not cheap cells destined for toys or other consumer devices, and presumably not a facility that cut corners. Ignition supposedly occurred in a late stage production area where cells are given their initial charge.
Heat is a factor, but not to the extent often advocated, and the manufacturers aren't ignorant of this. The operating limits are prescribed on their spec sheets.
Many possibilities, including cell damage from over-discharge, unbalanced cells combined with a poor, or non-existent BMS, or just plain poor quality cells.
The risks rise in multi-cell battery applications. A simple flashlight and two unbalanced lithium primaries has the potential to turn into a grenade. The warnings to replace cells as a set should be heeded.
There are millions and millions of forgotten Li-powered devices tucked away in drawers or other places, unused. Reviving them, or recalling them into service isn't quite as simple, or benign as many might expect, so some caution is warranted when attempting to do so.

There’s a reason why the Navy has the 9310 instruction for Li-ion batteries, applied afloat AND ashore…
Li-ion safety is serious stuff!
Li-ion safety is serious stuff!
NMC lithium has 2-3x the cycle life and 2-3x the energy density of NIMH. Nobody would want an EV with NIMH batteries!
I would, or lead acid.
2008 Toyota Camery hybrids have them NMH. So what are you saying?
Saying lead acid and NiMH simply are too heavyI would, or lead acid.
Better than having your garage burn down.
Just check out StacheD on youtube about your precious Lithium Ion batterys, or any other Lithium based batterys.
NiMH worked well enough for the first several generations of Toyota hybrids. Most never needed a battery replacement for the life of the vehicle.
Fear way overblownBetter than having your garage burn down.

You know how many e cars around here? Many! In the time I have seen at least 10 burned ICE cars, including my buddies Dodge diesel truck of all things - I have not seen one electric car fire
I’ve watched StachD actually subbed long ago. He’s about respect and proper use of the technology not fear like you
It lasted and that’s good but too heavy and memory effects with NiMH that does surprise me
OK, but those are hybrids… sure they charge and discharge at higher C rates but only for short periods of time. And the capacity is tiny as it only needs to move the vehicle a short distance. That’s not scalable to a full EV that needs to go hundreds of miles just on the battery or needs to be able to charge from 10-80% in 30 minutes thousands of times.
That's true, but the context we were discussing was hybrids, not plugins.
You forgot another first part; advertising. Anytime you see Flo, Jake, the Gecko, or Limu, guess who is paying for that?
I'd like to unsee Flo. But Mayhem is great. He was good in Rescue Me as Leary's cop brother.
