Yes I know guys here know their stuff, but the diysolarforum is the nuke engineers of batteries and solar. Its got some great info, but I got banned after two posts for "spam" I am not sure what I did, one post was on a teardrop thread, the other was a question about a charger. So watch what you say,ask post.
The guy who started the forum has a huge youtube channel with lots of info, although its more aimed at off grid and house solar with batteries.
Just pointing it out those who want more info that you need but from people who really know their stuff.
