I have had great luck with HOHMLIFE 18650s rated at a true 3015mAh in my Braun flashlights. I buy them at a vapeshop @ $16 per pair. Been running 8 of them for over 3 years in 4 different lights. No issues whatsover!
@@Bbernhardsr They are NOT regulated. They are hohmlife 4s, 3.6v, 63W,85W max, 22.1CDR, 31.5A MAX, 0.16 ohm lowest resistance. 10.85Whr (whatever that is, watt hours maybe?).
@@Bbernhardsr In my 390 lumen lights it went from a few hours with the blue cells like shown in your video to lasting for almost a week per light (2 cells in each). I let the built in charger do it all. I have one like in your video but have never needed it. I also have Braun's 500 lumen light. They don't last as long, as you would expect, being quite a bit brighter. Almost too bright to look at! Important at 53 with cataracts starting to form.
