I would spend a bit more for much more battery and use Olight RCR123/16340 I use the lighter greenish colored ones, they ARE protected for discharge, charge and really are light years ahead of my numerous AW of same size, I find AW lacking tbh just don't seem to have the guts whereas the olight ones keep my S1 Baton on highest setting for ages AW last 20 seconds then cut out wheras the olight ones really do kick, I have NITECORE and these act same as AW too.
