I've never been a fan of stacked batteries. So, I don't have the data to compare it to. Theoretically you would get longer life out of stacked 18350's (800mah x 2) vs a single 18500 (1100mah x 1) but you're not going to see any gain unless you plan on running them in a high volt configuration, which you won't do.
I've heard people complaining about stacked 18350's from the SVD reviews. Add your name to the list. Think I'll just stick with the 18500's. Thanks for the info Dust. I'm waiting for that dude to return from wherever he is. Should be early next week. I need him to recommend a charger for me too. I need to find me a little travel thingy to keep batts, attys, juice etc in. I feel like such a woman doing that but it is convenient.
