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. Instructions To use a tank, first fill the blank carto with e-liquid. Then push the carto about halfway up into the tank. Then, fill up the tank almost all the way, surrounding the carto, but leaving enough room for the rest of the carto to be pushed up to the top of the tank. Tank Styles Vapor4Life carries a few different styles. The first is a 3.5 ml dual coil tank, with 1.5 ohms resistance. It is threaded  for 808 batteries. This tank works with Vapor King Diamond and Stealth Series manual batteries, and the VGO. We also carry a 3.5 ml dual coil tank for 510 style batteries. It works with the 5V OMG mod.

The 6 ml dual coil metal tank carries 1.5 ohms. It can be used with Vapor King Diamond and Stealth Series manual batteries, and the VGO. It comes in green, white, yellow, blue, red, lime green, magenta, and lavender. We also carry another 6 ml dual coil tank, with 1.5 ohms resistance. It is threaded  for use with 808 batteries. This acrylic tank is compatible with Vapor King Diamond and Stealth Series manual batteries, and the VGO. Then there is a 6 ml dual coil acrylic tank with 1.5 ohms resistance. This tank is 510 style and compatible with the 5V OMG mod. Understanding Resistance CoolCarts have a high resistance, meaning they heat up less than WOW cartos. They offer  a good throat hit and produce a lot of vapor, but stay  cool while being vaped. Since they have a higher resistance, about  3.4 ohms, less heat is being used to generate the heating coil of the carto. They work well for chain vaping, and/or being used with a USB passthrough. The cartos generally do not warm up with continuous use. They hold more e-liquid that WOW cartos. The 3.0 ohm replacement cartos for tanks are similar to CoolCarts. Having a higher resistance means it takes less heat to produce vapor. WOW Vapor cartos have a low resistance so the coil burns warmer. The vapor they produce is typically warmer and thicker than that of the CoolCarts. That is why many people like using drip tips with this type of carto. WOW cartos vaporize e-liquid at a higher temperature, so when vaped continuously, they get warm to the touch. Since they get warm faster the CoolCarts, they use e-liquid up faster than CoolCarts do. The resistance of  WOW cartos is about 2.5 ohms. The 2.0 ohm replacement cartos for tanks are most like WOW cartos. Using lower resistance cartos means that the battery has to work harder, so the battery will drain faster than if being used to power a high resistance carto. We now sell dual coil replacement cartos in 1.5 ohm versions. We also have single coil replacement cartos available in a 2.0 ohm or 3.0 ohm version.
