LiFePo4 battery users

[Ticklebelly]

Interesting article and seems to confirm a capacity fade generally consistent with what is put out in manufacturer's data.   Data was collected from about 2012, for about 2 years; latest design batteries incorporate things like Graphine.   Energy density for a 18650 size cell is about right.   Article author has set 80% capacity as his end-of-life point, I wonder how many RV users would even notice that amount of fall off and run out and buy new batteries.   The test bed used seems to be a high end version of of the B6 device I mentioned earlier.
