If you google and look at images you will find many charts exactly the same but remember LifePO4 are different to AGM and lead acid etc. The discharge curve is very flat then suddenly drops off quickly so the accuracy of using voltage is very questionable. The more accurate way is to measure with a shunt.
Yeah I can see that. I watched some YouTube videos yesterday (solar garage guy) doing tests with charging and the cells getting full with lower volts going into absorption at different times. The relationship between volts and actual soc seems pretty thin.
