Most home storage is Lifepo4, rather than lithium ion.
It’s a bit more expensive, and only has 80% of the capacity. In tradeoff, it gains 3-5x the lifespan, and an inability to burst into flames.
Bigger brands tend to be more reliable in capacity and lifespan. Cheap ones are more hit and miss. It might be fine, it might fail after 3 years, rather than 10.


I live in the UK. At this point, most of the polite smokers have moved over to vapes. Those left are almost entirely rude wankers who don’t care where their smoke goes and who it affects. The smoking ban came in because 1 smoker can affect dozens of unwilling people.
I have zero issues with vapes. The effect on others is quite minor, outside a few fog machines disguised as vapes.
