Boon-dockers in general, which is where this thread is located, tend to be a bit more experimental than the general rv’ing public and hopefully will gleam from these discussions a variety of solutions for electric storage and select the one best suited to their needs.
I forgot to address your statement as far as a BMS is a must have, I believe if you do your research you will see that experts would disagree with you. This is not me saying it but the experts. Many good videos on YouTube with people that have a lot more knowledge than any of us.
