The 18650's are lithium chemistry and imho it's superior.
Too bad there arn't any tiny 500mL sized water bottle nuclear power sources.
If we had tho all you'd have to worry about is just the heatsinking of the lighting and not worry about the battery power. Hehe...
Yah given some of the P7 configurations I've seen on the two-mode units it's 1000mA low mode and 2800mA high mode. Now think about the size and capcity of AA cell at it's highest (currently to my knowledge the only company that holds the highest and repeatly shows up after testing as higher then thier market claimed cells is the Maha 2700mAh which tests at about ~2750mAh) size and you'll see how many cells you'll need to keep that P7 happy bright for any amount of time.
