Can I Switch To An 18650 In My P3D?

[Wassernaut]

Can I Switch To An 18650 (or 17670 or whatever the cell is that's twice as long and smaller diameter than a CR123) In My P3D? That's the simple question. I'm trying to get away from multiple cells in my lights. I now run either 2 primary 123's or 2 rechargables, I'd like to change to a quality single cell for the P3D, but don't want to destroy it with improper voltage, lose functions or have an adverse effect on runtime or brightness. Advice? Thanks - Larry

Note: I know this is sorta a "battery" question, but it's primarily about a specific flashlight, so I hoped this would be the proper forum.

No, It won't fit(too wide). Some 17670 will fit but you will get limited runtime on turbo because of the lower voltage(P3D uses a buck circuit). For more information use the search, you will find other threads covering this. Here's one: http://www.candlepowerforums.com/vb/showthread.php?t=175181&highlight=p3d+17670

Kinda a noobish question, what is wrong with multiple cells? Is it a problem with Li-Ion? Or just a matter of ease of changing in fresh batteries?
