About Charging

Never charge a mod battery via a USB port; always use an external charger (such as one from Nitecore). An external charger charges your battery more safely and efficiently. Additionally, using an external charger prevents damage to your mod from prolonged exposure to heat.

Safety

Mod batteries are powerful batteries and require a bit more attention than standard batteries. Always check if your mod has any damage before using it. If you notice any damage to the mod battery, do not use it! Damaged batteries can pose dangerous situations.

If you carry mod batteries with you, always keep them in a case or box. Never carry them loose in your pocket or bag! When a mod battery comes into contact with metal, it begins to discharge, which should be avoided at all times.

Never discharge your batteries below 3.1 volts. If the battery voltage drops below this level, the mod battery is often irreparably damaged. This is especially important for using mod batteries in mechanical mods that do not have built-in protections.
