Addix: Way to go. I did exactly what you're doing - I read about ecigs in the Times of New York and started to read about them some more. I came here and found a rich collection of quite caring and helpful people. I gotta say though that I was completely stupefied by the jargon, Ego this, tank that, dual coil, wick, atty... I needed stupid, or at least simple so I went and found it. I understood battery, long battery heats up something called a cartomizer and makes smoke-like non-smoke with nicotine. Screw cart into battery, press button, inhale, get magic drug. I only really understand the goal line, generally speaking, and using the [Colin] Powell Doctrine of Overwhelming Force to get there. So, I ordered a starter kit with the same battery you mentioned. Liked that, ordered lots and lots of batteries and lots and lots of cartomizers (Pay no attention to company marketing indicating that one cart = one pack of smokes, it just doesn't; I found myself vaping about twice the amount of carts, 4 of those versus about two packs of tobacco cigarettes, and I found my happy place at a higher level of nictotine than marketed as an equivalent of my Marlboro Ultra Lights (about 10mg nic per pack and I used 18mg per cart - you don't get as much nic by vaping and I was chaining the e cigs for a while, partly physical need and partly psychology; have seen similar statements from others).
And, yes, absolutely, I cared not one wit about battery life, I wanted the thing to look and feel as much like a tobacco cig as possible, I even ordered the stubbiest little bugger they had knowing I'd have to charge it often - at the beginning, I just flat wanted to be holding the same thing. So, if you think the KR bat/cart deal is the way to go, charge right in. That's what felt right to me and I've been tobacco free since just before Thanksgiving last year. I felt better almost instantly.
Right now, the only goal is not to smoke and your plan is a great place to start that. The rest of the possibilities, all the devices, e juices, DIY and the like can wait. I think you'll love it.
It is a tremendous road to be on, getting rid of tobacco in your life.
