I'm very excited in that the wifey agreed to get me a provari for Christmas this year (The wait is gonna kill me, but my little ego 1000mah and ce-2's will keep me happy until then ). My question however is what are the best batteries to get for it? I will be getting the extended endcap to be able to use the 18650's with it. As with all of our gear there are so many options out there in batteries, what do you choose? I know there is an amazing amount of experience in this forum so I'm pulling on the experts of trial and error. Great thanks ahead of time for the input!!
