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!
