The Fenix ARB-L21-5000U is a premium quality high capacity 21700, 5000 mAh lithium-ion battery specifically designed for high intensity torch use and is the perfect companion for for all Fenix 21700 powered lights.

As well as being able to charge in a battery charger (Fenix charger recommended) the ARB-L21-5000U has an additional feature that sets it apart from standard 18650 batteries as it has a built-in USB-C charging port in the top of the battery.

Using a USB-C charging cable this battery can be easily charged up which is not only convenient but can also save money on buying a separate charger. A charging indicator will glow red once the charging cable is plugged in and connected to power to show charging is in progress and it will turn blue once charging is complete.

Please note: This battery is larger than an 18650 battery and cannot be used in standard 18650 sized torches. Please check the dimensions of your intended application before purchasing, as they may not fit some products.
