Product Information
The Efest 21700 mod battery has a capacity of 3700 mAh! Its maximum discharge capacity is 35 amperes, making it ideal for medium-high wattages (up to 80 watts). This battery is best suited for regulated mods. For mechanical mods, the Samsung 30T is a better alternative.
The 21700 mod batteries are larger than the 18650 batteries. Make sure to check if your e-cigarette uses 18650 or 21700 mod batteries so that you purchase the correct battery.
About Charging
Never charge a mod battery through a USB port, always use an external charger (such as Nitecore). An external charger charges your battery safer and better. Additionally, using an external charger prevents damage to your mod from prolonged exposure to heat.
Safety
Mod batteries are powerful batteries and require more attention than your standard batteries. Always check if your mod has any damages before using it. If you notice that the mod battery is damaged, do not use it! Damaged batteries can pose dangerous situations.
If you want to carry mod batteries with you, always use a battery case or box. Never carry them loose in your pocket or bag! When a mod battery comes into contact with metal, it can start discharging, which should be avoided at all times!
Never discharge your batteries below 3.1 volts. If the voltage in the battery 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 protection.
