Gut check lithium 4S6P battery connections
Still working to figure out this whole solar battery thing. This is focused on: 1. The series interconnections between 3.2v lithium battery cells to create a larger 12v nominal pack. 2. The par...

Think you want to do 6p4s. What cells and BMS are you considering?
Remember RV usage is similar to house battery systems on boats. Not really similar to EV battery systems due to the constant loads and multiple charging sources.
Take a look at the following web pages:

Clab batteries 180AH 3.2v.
BMS I am still exploring but don't want to put that into this mix until the basic electrician approach is defined.
I'll take a look at the 6P4S vs. 4S6P. That does change some things even though the output is the same. Thought I had read somewhere that do P first and then S vs. the other way. It also affects in and out boards for BMS cell/pack communications and monitoring (less in and out boards at a pack level (4 packs vs. 6 packs).
Thanks
