In a recrnt thread it was being discussed that lifepo4 batteries only last so long before they start to degrade.

So in my opinion, charge LiFePO4 to 100%, and discharge to 0%. Use the capacity while you still have it. Daily cycle for solar is not strenuous on the iron
phosphate lattice much at all. Keep your batteries cool and balance charge (keep at high SOC to trigger balance circuit) every 4 months or so, and they
should last a long time.
If you want a conservative absorption figure, Victron recommends 3.525V. I now set my absorption to 3.6V, and set BMS HVD for 3.65V to avoid stressing
So trigger value would be 3.6 and release would be 3.65?
How low can you take the cells down before you damage them? Will states to take them down to 0%.
What should I set my cell under voltage setting to?
