Note: All knowledge in this post is based on what I remember from grade 10 circuitry. As such, there's a good chance that it's a bunch of lies. By all means, correct any of my errors.

Over the last week I did some work experience at Moli Energy (Maple Ridge, BC), which is among the largest manufacturers of lithium-ion cells in North America. After a few days working with the cell production line, I discovered that each cell is charged to 4.2V, with a 2200mAh and a 3000mAh size. Now, if what I recall is true, cells connected in series will have additive voltages, which means it would only take two of these cells to achieve a voltage rating of 8.4. Of the two cells, the smaller is 18mm in diameter and 65mm tall, and the larger is 26mm in diameter and 70 mm tall.

Again, my knowledge could generally considered to be bad, but this seems to me an excellent way to make small, high capacity batteries. In all my searching, I've never come across a mini battery with a mAh rating of more than 1000, so it seems to me that a battery consisting of only 2 cells could open a lot of options for smaller guns (most batteries are 7 to a pack, yes?). My sad lack of a gun, however, means I really have no idea as to the specific dimensions of the battery compartments in most guns. I'll have to ask my buddies that actually do more than read forums.

One thing to consider while reading this is my complete ignorance to any of the more complicated aspects of current discharge. I don't know their tolerance, I don't know their discharge rate, I don't even know if they follow the same charging procedures. They are, however, used in Milwaukee's cordless line of power tools (which I understand are pretty sexy, as far as those things go), so they must be moderately good at things in general.

Alas, they don't just retail their cells. They sell directly to battery pack manufacturers, so getting hold of some might prove difficult. I also have no idea what price range it would be. And those of you who want 9.6V are out of luck: you'd have to try 12.8V, which I can't imagine being good for a gun.

But anyways, if any of you people that know things could come in and clarify any erronious points here, I would much appreciate it.

Edit: this may well be in the wrong section, but I don't feel it's partcularily fitting in accessories or gear, so here it went. By all means, move it if you disagree.
