Hello Learned ones!
I'm hoping someone can explain to a newbie some discrepancies I've noted as I rebuild my RV pack. FYI - the front page picture on the facebook group of the same name as this website shows the picture of my first battery build. This 10kwatt 48vdc behemoth battery, coupled with 2200watts of roof mounted solar, were able to run the air conditioning/microwave/fridges/etc on my motorhome 24/7. It worked great but....... it needs improvement.

As far as I can determine, the Lii-500 test range in Normal or Fast Mode ranges from 2.8v to 4.2v.
1 - How do you measure "True Remaining Capacities" for cells that have voltage cutoffs higher or lower than this range? Some cells range from a cut-off low of 2.75v to a cut-off high of 4.35v.
2 - I normally discard cells that have less than 80% capacity remaining - if True Remaining Capacity cannot really be measured in all cases with the Lii-500 due to question 1, what do you do in those cases?
3 - With a tester that will discharge a cell to 2.8v - will this damage cells that have a low voltage cutoff of 3.0v?

Thank you in advance for your assistance.
