The curve seems to be pretty lineair. So I think you can do another 5k cycles and have 60% left, once more for 40% etc. A quick search didn’t reveal a full curve chart to zero though. I know that a lot of cheaper LFP cells on aliexpress are used “grade B” cells, eg cells that had an original capacity of 120Ah that are resold as 90Ah cells after their first 5k cycles. There is a chart for 3k cycles here: https://www.ctechigroup.com/deep-cycle-life-lifepo4-cell-3-2v-280ah-for-electric-truck https://www.ctechigroup.com/deep-cycle-life-lifepo4-cell-3-2...
