Charging inside your house is very dangerous, especially in NA where most houses are wooden.

Same is true of cellphones and laptops. It depends on the brand.

1 scooter battery equals several or tens of notebook batteries, mobile devices generally use safer li polymer ones nowadays.

These scooter batteries sustain intense charging and discharging cycles, I won't bet my house and life on it.

At my hackerspace we charge our 18650 cells inside those green ammo boxes. Battery lockboxes are a way to stay pretty safe, even if a li-on, li-po, or lead acid battery explodes, in a steel box it can't do so much.

Obviously, doesn't help without removable batteries, which are more common on ebikes.
