Hey all...I currently have a couple mods that take 18650 batteries and I've been using a couple 2000mah (eFest) batteries I bought awhile ago. I'd like to get something that will last a bit longer however but I'm not sure exactly what to get (or what NOT to get). Since I only intend on using these in regulated mods, can I simply get the highest mah batteries I can find or are there other considerations I should take into account. This might be a very general question but all the battery safety talk I've heard since I started vaping has me wanting to be sure I'm getting the right product. Thanks a ton in advance!!!
