Thanks for the feedback fella's, but I meant lithium (as in Energizer) not Lithium-Ion. But all the information is helpful for sure!. The Maratec 929 looks sweet, the cooling fins are anice touch as most of other seem to have a problem with getting rid of excess heat. And I'd like something that won't roll away when I lay it down!

On another note, the 10440 cells are interesting, but I wouldn't dare place in my old Fenix Rebel units. Or could I?
