Basics of Lithium conversion... I'm lost!
I did a search and it's mostly Greek... to me. I'd like to know the key points for, hopefully, a straight across lead/acid to lithium conversion. My old Flow-Rite watering system just overflowed 2 c...

Have you examined a battery management system for an automobile versus a battery management system for a six hundred dollar lithium battery? Apples and oranges. Better said a durable circuit versus chew and spit.
The navy and air force refuse to replace AGM batteries in military aircraft because it is not feasible to construct chew and spit management systems for small batteries with extreme high reliability.
A half dozen years of actual use is a ridiculous claim for reliability. Lithium batteries are said to yield six thousand or more cycles of usability. Tell me, how many years of service is that? Like with vaccines or tires or light bulbs, only real life and real time consumer testing and use are going to reveal the durability of small battery BMS systems after six years, after ten years after twelve years. If you cannot get six thousand cycles out of an expensive battery then what is the use of spending thousands on a battery bank? How many cents per cycle is rational or irrational?
I view this the same way as I do 19.5" four hundred dollar tires on a daily commuter car. They give far less mileage than a conventional tire, are more easily punctured, more difficult to service and spend 0.000% of the time at the rated limit.
What the hell good is a lithium accumulator in a weekend warrior or even 2-week campout RV? They may (or may not) last ten years. In 10 years RV's may have something akin to wall packs making conventional batteries ridiculous.
Immediate use involving heavy continuous cycling is the sole justification for spending thousands of dollars for a specialty battery bank.
Of course there will always be folks who glad hand others into thinking a thousand horsepower McLaren is absolutely necessary for 5 mph stop and go. My lights will shine just as bright as yours :)
