I was kidding about the battery fire, but some people worry on this forum about the most minute of things...
There are very real risks, especially associated with cobalt-containing chemistries such as most used EV batteries. LiFePO4 is benign and probably the safest of any batteries you will find available for RV use today. I think people who put used Tesla cells in their rigs, for instance, are asking for future trouble in all but the most sophisticated builds, which very few people do. By the time you get to a point where you've sufficiently mitigated the risks you might as well have gone with LiFePO4.
I went with a large Victron system and lots of residential panels and LiFePO4 batteries, and don't have to worry about energy management. The same equipment I'm using today was on the market in some variation or another five years ago, with very few differences. Solar tech is not changing that quickly, but costs of the existing technologies are slowly trending downwards.
