It is often said thst Lead Acid and AGM batteries exhibit a DoD range of 50% to 80%, emphasizing the need for cautious discharge levels. Lfp batteries, boasting a range of 90% to 95%, provide exceptional flexibility without compromising longevity.
I think to be on the super safe side and maxing out lfp battery life span it would be a good idea to not exceed the dod to excess and use only 85 to 90 % of its capacity.
That's what I do with my EVs lfp battery by the way. It seems to be working from the battery health measurements.
