My comment was in response to "I wonder if there was a period when they were very unsafe, or if it was always just a marketing-driven perception."
There is an accurate perception of some small lithium ion batteries being dangerous due to poor quality and regulation. Same with SOME EVs.
This perception bleeds over into large house batteries, which are much better constructed, tested, and regulated. Sorry I was unclear.
