Fenix Battery ARB-L21-5000U 21700

ARB-L21-5000U 21700 Li-ion battery with a capacity of 5000mAh. The capacity of the 21700 battery is twice that of the traditional 18650/2300mAh battery, which provides sufficient power for flashlights and other electrical devices for a long time. Multiple protection against overvoltage and undervoltage ensures the safety of use and good performance of the battery. The steel jacket riveting technology completely protected the battery from damage. Internal gases are quickly expelled via pressure relief openings.

Thanks to the integrated USB-C charging function, the 21700 can be used like a power bank without additional chargers. The plus pole is slightly warm during charging. As soon as the battery is fully charged, the plus pole is cool.
