You can cut the prices in half by buying inferior products, those prices were taken from a direct lookup of the current Battleborn battery prices.
Anything else is cheap chinese junk and at risk of a cell failure and fire risk.
I honestly don't have a horse in the race, as I do not think the technology is ready yet to adopt at its current price points for all but those that like to experiment with new things, (A proper full disposal cost should be included in the purchases of all lithium batteries from my point of view including the cost of 90-95% component recycling), nor do I honestly care if you go cheap and end up burning your rig to the ground to save a few dollars, I can only offer up advice to not take cheap shortcuts and let folks decide what degree of risk is acceptable to them.
TL;DR I don't give two ***** if you decide to cheap out and kill yourself, I can only suggest that you don't.

Very true, costlier grade ‘A’ cylindrical cells of high uniformity (ain’t no free lunch), as does Aims…

As long as you're buying the top end Lithium RV deep cycles you'll be good, just make sure you have budgeted enough to get equivalent AH's to your existing setup and for the appropriate changes in your DC and AC->DC Charging hardware.
The more budget friendly Lithium batteries have record incidents of cell failures, as to bring them down in price, the quality and chemistry of the battery is cheapened.
You should budget around $2000 for 200AH of Quality Lithium battery capacity and around $350-400 for the charging hardware as a good starting point.
For me, I'll likely do the shift to Lithium as soon as Battle Born batteries get equivalent AH capacity to the J185h FLA batteries with a similar foot print and are price equivalent to their FLA predecessors in my system currently.

First off, Solar panels do not discharge energy into the night.
Solarnight discharge
The back flow diodes and solar controller will prevent it. There is a minor voltage Vbf but it's very small. Also, it doesn't discharge back into the either or sky, it's just a resistance load to the batteries.
Most modern solar electronics have some sort of circuit protection. Even so, since you seem to have power in the day with sun, I would guess your solar charge controller is functio I g to some degree. Since your battery dies quickly, my guess.is.you damaged your batteries BMS. You'll have to do or have done, your own testing. Good luck.

I see you're taking compression pretty serious. I started out compressing, but after looking into it a bunch, it seems compression is of only some minimal benefit to longevity.
With the lesser cycle cells, you'll get some marginal extra life, or with used B or C grade cells. The K cells will last 17 years even if you mildly abuse them. If you really take care of them and constantly keep them in the 60-80% range, they are estimated to last 32 years. And that's without compression.
Not saying compression isnt correct and I know the manufacturers have always recommended it, I just can't see going through the hassle with these new LFK cells.
