For the few of you who know me, you know I'm new and totally stupid to all this. I have been following the advice from members here and I am acquiring a ton of awesome stuff and I'm not wasting a lot of money in between by buying the wrong stuff and learning the hard way. The idiot's guide to life. LOL I am so thrilled with my Divine Tribe V3 and some of the other items you all have recommended and now it's time to upgrade the box mod. I currently just bought the Joytech eVic Basic and it's very cool but it seems to run down pretty quickly. I don't have any clue what to ask for or to look for. I see some are "Firmware Upgradable" What the fuck? Firmware in a battery? OK, whatever. I'm sure everyone has their own opinion based on their own needs but since I don't even know my own needs (other than longer life) I am open to any and all suggestions. So, which one should I buy? And.... thank you.
