I just ordered a Electrolumens Big Bruiser and would like to purchase 26650 batteries before it arrives. There do not seem to be a lot of options which has me a little concerned and I am new to high end flashlights. Does anyone have any suggestions? How about the High Power LiNiCoMn 26650 3.6V 3600maH from batteryspace.com? This is my first post...so thanks in advance for any advice you can lend!
