Chargers, Batteries & Wraps

We highly recommend using an external battery charger for 18650 battery mods, as it helps with balanced charging and prolongs the life of the battery and mod, such as from worn out microUSB port.

Never use damaged or improperly wrapped batteries with this device. We recommend all 18650/20700/21700 battery mods to use matching batteries with similar brand, model, and battery state at all times.
