I'm really not sure how to correlate these graph results to actual usage on XM-L2/SinkPAD setups (yes, they are all mod'ed but they are still flashlights and XM-L2's are already in production lights, maybe SinkPAD's some day). Also, how do you determine internal resistance of a battery based on these graph results? QWell, one batt may be better for the frst 500 mah, another past that point -- very confusing, which is really better? I can only go by the first couple of minutes because that's how I and most others test lumens/throw - fresh off the charger, 30 seconds, then throw.
SinkPAD's, I believe, change everything, more so than the XM-L2 - can't compare to a high draw stock light like the HD 2010 because the voltage demand (Vf) is different.
NightCrawl - Judging by the charts, there is only one battery tested that is 4.35v (LG 18650 D1 3000mAh), and it's results are mixed, not across the board better - first 0.5 Ah, the Samsung is much better, then the LG is a little better after that. Are there other 4.35v options, maybe better? What do you need to charge them?
