It's a shame that Kokam only has a small cluttered graph for the 4000mAh cell.
However, from what I see of the 2400mAh cell discharge graph, it's not anything special. For example, here's a comparable capacity flightpower 2500mAh cell graph:

Notice that it remains above 3.4V until about 80% of pack capacity (2000mAh) versus the Kokam pack only staying above 3.4V for just over 50% of pack capacity (~1200mAh).
