Good luck with the build, I really like the design model of the SBMS0, there is certainly a learning curve and it is not always the best option for beginners, but its a pretty powerful, flexible, and unique little BMS, and a great value. Plus Dacian seems like a great guy, smart, helpful, thoughtful, though at times a bit inflexible/single minded.
If you haven't already these:

And this thread
...Are good resources for the SBMS0
Beginner: How to Find Happiness with LifePO4
Intermediate+: Introduction to Lithium Battery Systems
Intermediate+: LiFePO4 on boats
...Are good technical introductions to lifepo4, and how to build, maintain, and protect LFP battery banks. I recommend reading all three if you plan to build and maintain your own LFP system.
I would definitely strongly second your reccomendation to watch some Will Prowse videos for beginners interested in building their own LFP battery packs. Though there are people with more depth of knowledge than Will, he is a great explainer, and great at explaining things simply and in a beginner friendly manner. This quality is worth its weight in gold in technical topics. I would just caution that his videos and his 'blueprints'/examples should be starting points in your design, not necessarily followed to the T, he often sidesteps or overlooks safety consideration that may not be important for hobby systems but are important for a vehicle, skoolie, or home, and tends towards cheaper not always reliable amazon components. With those caveats in mind, I have learned a TON from his videos and very much value his content, and respect his ability and dedication to explaining complex topics in simple terms. I would highly recommend his content to any beginners interested in learning about solar or lithium batteries. Amy at the Altestore and Pacific Yacht Systems are two other good resources for beginner friendly electrical and solar knowledge
