I just got a new tenant in my rental house and this time I had to add a clause to the lease enumerating brands of lithium-ion batteries the tenant is allowed to keep on the premises. These things are basically grenades that you can buy for $2 on Temu. Stronger regulations needed.

How is any tenant possibly supposed to comply with that? Rip every piece of electronics they buy apart to check?

It's about highly energetic battery packs for things like bicycles and scooters.

Doesn't the same question apply though? How is the bicycle and scooter owner supposed to find out the exact brand of the cells used, rip apart the pack just because the landlord doesn't have insurance/require tenant to get insurance?
