I made the mistake of buying a Samsung washer/dryer set in 2017. The washer actually still works and the seal has held up well, but the dryer drum jumped its tracks within the first year, and both have been plagued with gremlins.
Fuck Samsung appliances and honestly most things Samsung sells.
AFAIK, LFP thermal runaway can’t start fires. NMC or other lithium chemistries can and they scare me, but LFPs are pretty damn safe. That being said, I’m still stoked for sodium chemistries to be developed. If the round trip efficiency issues can be solved, then I think it’ll be a great solution for residential power storage.
