Thanks again Barkuti, but I was looking at not only those V vs. capacity graphs, but also the graph titled “Acebeam EC50 Gen II, Highest mode, Fan cooled” from user maukka in his review of the Acebeam EC50 Gen II (which is the light that I’m buying the battery for).
Unless there are two types of LiitoKala 5000 mAh 26650, his graph shows that the Vappower maintains turbo mode longest.
