I’m really thinking about getting this light. My problem is, that I don’t have a 16340 so far, so I want to know with which battery you had the best experience? Which has a good capacity and offers some nice Amps?
If you look at the test graphs in the ebay listing, the Yezl 16340 has the best capacity. They are also capable of 3.2A max discharge, so can provide plenty of current to the Trustfire Mini-01.
The light gets very hot on high though, so wouldn’t be suitable for extended use on high.
I used 3.2v LifeP04’s in the light also, and the light isn’t as bright, and doesn’t get as hot either. These cells aren’t protected though, so the light might over discharge them if you aren’t careful.
I tried primaries, 3.2v LifeP04’s and the Yezl 3.7v. The 3.7v are definitely brightest by a nice margin. The fact they are protected is good too, because it is easy to over discharge(a non protected cell) because the light drains the cells so fast.
It gets hot but still ok to hold on a primary or LifeP04, but with the 3.7v it gets very hot within about a minute, and too hot to hold for long after 2-3 minutes.
