Sub ohm or low resistance tanks should only be used by experienced users. Additional safety precautions should be taken when using a sub ohm tank. This tank will only work on a mechanical mod or a regulated mod capable of firing resistors and sub ohm atomizers. For example, if it has a resistance of 0.2ohm, its mod must be able to fire atomizers of 0.2ohm or less. You should also ensure that your batteries can handle atomizers and sub ohm resistors. If you are using a regulated mod, make sure you can handle the amplifiers. Incorrect use may cause injury or damage. For mechanical mod users, use batteries of 30 amps or more.
