About a month ago, Vapor4Life began selling mods (modified batteries). These
other batteries are capable of using single cartos, or special cartos with tanks. Tanks can also be used on our Original Vapor King Diamond and Stealth Series batteries. The purpose of a tank is that it allows the vaper to enjoy their e-cigarette longer, without having to refill with e-liquid as often. For most people, it will last all day without needing a refill. All of our tanks come with two drip tips, and one carto designed specifically for these tanks.
