I just recently received my v11r from Battery Junction and can't figure out a battery issue. When I install a 123A it works perfectly. I hooked up the AA extender and put in a AA Sanyo Eneloop 1.2v and it does not work. It will work with a standard Duracell AA, but only after I take off the extender, put back a 123A, and then reinstall the extender and put in the Duracell. Selfbuilt did a review on this flashlight and I remember he tested it with the AA Eneloop 2000mhz, which I believe is the exact battery I have. Any ideas what is going on here? Any help would be greatly appreciated.
