External battery mods are advanced vaping devices that use removable batteries (usually 18650, 20700, or 21700 cells) to power the device. Unlike mods with built-in batteries, these allow you to swap out batteries when they run out of charge, providing more flexibility and longer usage times. They often come with features like adjustable wattage, temperature control, and custom settings for a tailored vaping experience.

External battery mods offer several advantages, including extended battery life, as you can carry spare batteries and replace them as needed. They also provide more power and customization options, making them ideal for advanced vapers. Additionally, when the battery degrades over time, you can simply replace it instead of the entire device, making it a cost-effective option.

Proper care is essential for the safe use of external batteries. Always use high-quality, authentic batteries from reputable brands, and avoid using damaged or torn battery wraps. Store your batteries in protective cases to prevent short-circuiting, and never expose them to extreme temperatures. It's also important to charge your batteries using a dedicated external charger rather than directly through the mod, as this can prolong their lifespan and enhance safety.
