We supply a range of Efest batteries with several different amp limits and capacities. Choose which one will work best for your build! The higher the capacity, the longer the battery will last on a charge. The higher the amp limit, the safer you will be on sub-ohm builds.

We do NOT recommend using any 18650 battery for ANY build below .3 ohms.  If you do, you do so at YOUR OWN RISK.

This 26650 battery has a much higher amp rating and lasts much longer than 18650 batteries.
