I've been eyeing the Bogger mini bottom feed box mod, but don't know the first thing about them. First question most of my cartomizers I have right now are 808s. Can I use a 510 to 808 adapter ? Thinking about buying the 510 atty but have no clue which to get for the mod. And lastly they don't sell the 18500 battery on the site. Where is the best place to buy the battery? Thanks
