Danny, have you ever seen this graph? It was surprising to see that going to 4.2v/cell has such a dramatic effect on cycle life compared to 4.1. It would be an easy rule change to make max voltage 4.1 and batteries would be much happier for it. Now that we're not trying to compete with NiMH, why not?

Interesting that it's so dramatic a difference. I have always understood that battery damage occurs at the "ends" of the capacity limits. The discharge cutoff is 2.5v. I wonder how that test would turn out if the LVC were 3.0v?

Here is some more info:
