Since youre just starting out, a few questions....
are you using a regulated mod or a unregulated stick?
is the tank you are using a tootlepuffer (mouth to lung) or a BIG-AIR-CLOUDS-BRO-CLOUDS (direct lung sub ohm) tank?
the reasoning behind the questions is there are different drop-in and rta tanks for those methods. a good tootlepuffer would be an innokin zenith or joyetech cubis, while for clouds the vaporesso cascade and smok beast series are good.
if you are looking for best coil longevity, you really cant beat an rta, (but since youre new, here are a few safety stipulations) i recommend using only a regulated mod and good batteries, an external resistance checker for testing builds, and a good coil jig. a regulated mod with good batteries like any of the 80 watt single 18650 devices ( there are too many to mention), or even a dual 18650 mod will have most of the safety features you need for newbie building. the resistance checkers are dirt cheap and run on a couple of AA batteries, this will help you figure out your wraps/ohm balance during early builds and keep you honest as you get more proficient.
@Mooch has you covered for good battery recommendations in his blog, and he doesn't sugar coat the ratings he gives. and the coil jig will save you from embedding the atties in the wall from frustration in getting your builds made. Wow, that got rambley didnt it....
