that is kinda misleading it, you are not hurting it by tanking it to 0%, and there is no reason to be afrade of doing so. the rated life span of a LiFePO4 is based on cycling from 100% to 0% many many times. I think the older batteries I was working with that had a 3500cycle life, if you cycled then twice a weekend for 33 year they would at that point only have 80% of the capacity left. ther new ones coming out are being listed as 8 to 10K cycle life. all staying above 10% does is give you a bit more cycle life than they are rated for, so ya it is good practice to stay above 10% but your not doing damage by going below.
The point is still the same, you can use most of the rated amp-hr in a lithium which means you can use a much smaller battery bank and still have the same amount of USABLE amp-hr. Heck, when you buy them, they automatically jump you up to 100amp-hr anyway.
