As with anything involving electricity, safety must be your top priority. Batteries, coils and mods with all their various properties and calculations can seem overwhelming for anybody, especially those new to vaping. There are some excellent tools online to help sort all this out.
An understanding of Ohms Law and the tools to calculate it are invaluable. One of the best places on the web to start is at http://www.steam-engine.org/ohm.asp. Be sure to check out the tabs at the top of the Steam Engine page for many other useful vape related tools for coils, batteries, mods, juice and wire. If you build, use a mech mod, or want to do either you'll want to bookmark this page.
Mooch on the ECF forum shows a list of some common batteries that he has tested and the results. Note how many of the claims that manufacturers make are higher than the actual test results. https://www.e-cigarette-forum.com/forum/blog-entry/moochs-recommended-batteries.7593/ (Click the thumbnail in the first post for his battery recommendations.)
A long but really useful video where the Vaping Biker interviews Mooch and goes through an informative Q & A: https://www.youtube.com/watch?v=KtMRuivHn68. Even if you don't watch the video all the way through, the first ten minutes give you a bit of background about Mooch, his expertise and experience with batteries and safety.
Baditude, also from the ECF forum, offers a lot of great in-depth info about battery safety as well. https://www.e-cigarette-forum.com/forum/blog-entry/9-battery-basics-for-mods-the-ultimate-battery-guide.4848/
