I should judge the accuracy of what someone wrote nearly a decade ago by what I think of what I think they believe today? It's a popular enough viewpoint today, certainly, but it leads to throwing out huge swaths of perfectly good work that could be useful. Obviously, I reject it. I don't know the guy, I don't know what's happened to him or not in the past decade since he was writing on the deep truths of RV solar. I do know that the more I learn about solar from hands on operation, the more his writings reflected what I'd found through experimentation/analysis/etc. You could apply plenty of his rantings to some of the off-grid battery destroying systems presented on YouTube as Grade A Amazing builds and improve a lot on those systems. But, if you're only willing to consider the viewpoints of those you would consider show clear thinking, which largely translates to "agrees with what I already think," you're welcome to go through life that way. I tend to find that dreadfully boring and a good way to miss an awful lot of really solid knowledge. I'm happy to learn about lead acid battery quirks from people who've lived with lead acid for half as long as I've been alive, even if I think they make some pretty dumb decisions in life. I know they question some of my decisions back. Anyway, your mind is clearly settled and the issue is closed on this particular bit of writings. You might go find some of SunKing's rants about "max smoke charging" useful as well, if you're dealing with off grid lead, but I guarantee you won't like him much as a person either.
