So long as you don't go over 60 watts, I recommend a Samsung 30Q battery. Get two, that way one can be on the charger when you vape the other. If you really have to have all 80 watts, get the LG HB6. And get 4 of them and a bigger charger as you will be changing them out a lot more often. Chargers can be safely bought on eBay from sellers with good feedback, but buy your batteries from the "trusted sellers" block in Mooch's chart, above. For charger brands, thing Xtar or Nitecore. I am sorry you didn't understand the battery was not included. Smok's website does not say this specifically, but it does say the mod uses an 18650 cell, and does not list this in the parts that are included in the kit. Welcome to the board.
