I lived 10 years off grid in vans and rvs, and now I mine bitcoin and charge my teslas with offgrid solar. I have built systems with every chemistry, even lithium polymer and LTO. And FLA and AGM. I have a lot of experience in this realm. It does not sound like youv'e seen my videos before.
Lithium packs are not a nightmare to recycle anymore. There are huge corporations fighting to recycle them now, and the tech has improved a lot. I could not say this two years ago. Lead acid is easier to recycle, but the cycle life of those packs, and sulfation you have to deal with, make them horrible for the environment. Cycling them deeply kills them fast, even the expensive ones. If you do not cycle them deeply, FLA will last for decades, but will cost a lot of money , space etc. And you need to maintain them. Lithium ion chemistries such as LiFePO4 are far superior.
I think you need to get your hands on some cells and actually build a pack. Test the coulombic efficiency and usable capacity at various temperatures and you will be blown away. And you will save a ton of money over lead acid. Lead acid is very expensive, and I would make a lot more money if I sold them. I also do not sell anything on that website, it only has affiliate links. I am not on any sponsorship contracts or have loyalty to any company. Most of my review videos are me bashing design errors and various solar companies. I do not think you have seen my videos, going by your comment. It is a little bit cringy, unfortunately.
