I never looked at the current drawn by my flashlight or by the bike headlight I used to test a whole bunch of different 18650 batteries. The flashlight has a Cree XML-T6 LED and the headlight seems to be two Cree Q5 LEDs. Even the newer Cree XM-L2 has a maximum drive current of 3000 mA. I'm not into high priced flashlights but do like to use batteries that don't need to be charged frequently. I don't know exactly what current draw constitutes "high drain" but would think that is the case for cordless tools like a drill. Lumitop lists the output for the $40 B01 headlight as 900 lumens which would be consistent with using either a single T-6 or L2 Cree LED. The T-6 tops out at about 950 lumens and the L2 at 1100 lumens. If so, the battery drain should be 3A or less.
