Mechanical mods are not regulated, and therefore include no short circuit protection for the battery other than ventilation (if ventilation exists in the design of the device). When using mechanical mods, please be sure that you know the dangers of not having circuit protection. Lithium batteries can be volatile and vent or explode, causing injury and damage to property. This can happen if the batteries are not handled properly, if the resistance level of your coils is too low, or in the event of a short circuit. We recommend using an Ohm reader to check your coils before you start vaping with a mechanical mod to ensure that you are vaping at a safe resistance level. By purchasing and using any mechanical device or lithium battery from our store, you agree to take full liability and responsibility for it’s use. In no way can VAPEBOX or it’s operators be held liable for any misfortune or harm caused by the use or misuse of this device.
