I was searching earlier today and stumbled across a great thread in the "battery section" I believe, about a comparisons of CR123 batteries and thought I had saved it but now I can't find it. It was full of charts and showed battery life on .5, 1.0, and 2.0 amp use I believe. I found a post from LEDninja that looked like some of the same charts but I couldn't find anything in a search on his ID. Any help finding me this post would be appreciated. Thanks.
