External Battery Cells are the source of power for External Battery Mods and Kits, which unlike internally built-in battery mods and kits, require separate batteries to be inserted prior to use. Please note that External Battery Mods and External Battery Kits do not come with the external battery cells required, but can be added to your new Mod or new Kit at a discounted price using the drop-down menus on the product pages. Experienced vapers know all too well the perils of battery life depletion, in which the battery capacity diminishes over time due to the half-life of lithium-ion cells. One of the many benefits of external batteries is the ability to replace them once they can no longer hold their charge efficiently. Those wishing to discover the “eternal battery life” in which their device never dies can benefit from external batteries and external battery chargers to ensure they’re always powered up throughout the day. Shop our fine selection of external batteries of all shapes and sizes, from 18650’s to 21700’s, we’ve got it all! Let’s not forget about the external battery chargers, they are a vaper’s best friend when it comes to ensuring external batteries are fully charged and at a safe ampage.
