Safety rules

To correctly use your Samsung 21700 battery, our A&L pandas will remind you of the essential safety rules :

• Always keep your batteries away from heat and magnetic objects. To do that, you can count on cases and holders (sold separately), entirely made of plastic and silicone to ensure non-conducting and entirely safe materials
• Before any use, check the cover of your battery, and the place of the battery in your mod. If you see, a damage or leak of e-liquid, do not use your battery. You can fix it with wraps (sold separately).
• Favour an external charger (sold separately) for the recharging of your battery. Much more adapted and secured than a USB port, the latter favors the lifespan of your battery.
