How often will you fully cycle a home battery? At 100 cycles a year it would take 50 years to deplete a 5,000 cycle battery down to 80%. Another 50 years before it was 50%. There is no way the casing would be fully intact and the electronics even be functioning after that long. Current LFP batteries should last multiple decades as a home battery. The already have low flammability. The price is getting more affordable. They could just be part standard of a home electric system in a decade or two, like a whole-home surge protector.

> The already have low flammability. Low rates of spontaneous thermal runaway, sure, but they still are extremely flammable if externally ignited or physically damaged. A house fire that could otherwise be put out might turn into a full disaster. An earthquake that physically damages the battery pack could cause a fire that would have otherwise not happened. A flood or minor tsunami might allow for early evacuations and most lives saved, but now the entire town is on fire instead of just water damaged, if every house has a massive lithium pack in their basement.
