Efest LUC 2 fits 21700 comfortably

[UncLeJunkLe]

I have an Efest LUC 2 and it fits 21700 batteries very comfortably. There's a good 3mm clearance between the battery and the positive contact when the spring loaded contact is pulled back to it's max. Very easy to put in and pull out a 21700 without top of the battery wrap touching anything (and ripping) as long as you pull it back the whole way when inserting/removing, which is easy to do.

I always assumed it wouldn't take a 21700 because my LUC 4 doesn't.

Just an FYI for anyone that cares lol

Just measured it. There's actually a good 7mm clearance. Even better, even safer. This is with the Avatar 21700 batts I got with my Pico 21700 mods. I don't have any others to test/measure.
