I can somewhat get a Samsung 18650 protected convex top to work, in the F3 L2, but can’t screw down the bottom cap all the way, so it’s functional, but I guess water could easily get inside.
I usually use a Samsung 18650 A26 2600mAh laptop pull flat top in my F3 L2s.
Man that sucks. So now I have to find 67mm batteries for these lights. Why the heck would they make the battery compartment so damn small and not fitting some of the most popular cells. Very frustrating. Might just resell these.

It’s a zoomie, so that’s unavoidable anyhow
Have you looked inside the tailcap? Looks to me like that huge long battery contact button in the tail could be shortened, or the spring behind it shortened, for longer batteries.
It’s a typical H-M-L-strobe-SOS driver (with a big spring on that).
I figure I can put in a better driver with a shorter spring easily.
The pin does not go all the way down when you push it - there are ~3mm of space you can easily dispose.
tested it - if you leave the pin away and possibly solder the spring to the switch (otherwise it just drops around) and a Samsung 26F fits without a problem.
Mine came in today. I only played with them long enough to know that they light up. all were focused. Adjustment is tight which is good. I think I’m going to like these lights. I just got to tear them down and start modifying them. For $6, definitely a steal.
Guys I just got mine today and my NCR18650A fit without a problem. I mean it’s a little tight screwing the cap back on, but nothing extreme and I am able to screw it all the way down. Is this a big problem if there is a little pressure on the battery?
