I think that the C rate is still useful info, but I also thing that varying the C rate to a constant LVC and maximum temp would show the ultimate durability and performance of the cell.

I also think that using pack that is assembled should be manditory. I've been pondering how the tabs have been failing on some brand name lipo's during use, but the manufacturer has obveously tested them at huge amp numbers. The problem I believe is external to the cell, it's related to the method of assembly. Specifically the manufacturer is spot welding the tabs and them folding them over. I'm confident that the pack no longer has the ability to perform to the specs that the individual cell had.

I think assembly methods could even cause localized heating at the tabs of the cell, causing heat damage while the rest of the cell is at an acceptable temp.
