I have a cig style battery that uses the same threading as Blu but I can't use it anymore because I refuse to buy there prefills. I know blu carts fit on this specific battery because I used to use them when I first started vaping. I'd like to figure out the threading so I can get the appropriate adaptor to put 808 Vapor4Life carts on it. As of now it just sits here collecting dust. Anyone know the threading of Blu? Is it a common, or is this battery ready for the trash? Thanks all.
