I just got a new SB and was wanting to order a set of RCR123a's to try out vaping at 6V. Can someone recommend a good vendor or set of batteries that will work well for me. This is my first mod and first time having to deal with batteries that are not built in to the PV, so I'm a bit weary. Also, the atomizer that I grabbed from altsmoke doesn't have a resistance listed (at least that I can tell). Will it work running at 6V or should I also pick up some higher resistance attys? Here's a link to it: AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | The Yeti/eGo/510 - Atomizer - Atomizers - Accessories Thanks!
