So I know that joyetech sells a 3400mAh battery for use in the eVic, although when I went to my local B&M they were out (although they were at the owners house) I am wondering what kinds of batteries can be used in the eVic. I am going to be buying a mechanical here within the next week or two and want to buy the best battery possible that I can use in both my eVic and my mechanical. Whichever one I end up buying.
