Lithium Battery Charging System
It is time for a new battery in my '04 Lance 921. I am looking at an Interstate battery they sell up the road. But through my research into charging systems/problems, I got to thinking about Lithium...

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.
The latest LF280K are 3500 cycles without compression and 6000 with, I would say that’s a little more than minimal. If you don’t restrain them I would suggest you keep a real close eye on your cell connections or go flexible buss bars because of the expansion and contraction of these cells. I have 640 lbs of compression on mine per the manufacturer and they still expand and contract with state of charge.
ETA: Also these are in a off road 4x4 and I can’t have them bouncing around, these mount on rubber isolators as well.
