Fenix ARB-L21-5000U is a high-quality 21700 lithium-ion battery with an impressive capacity of 5000 mAh, equipped with an innovative charging system via the USB-C port. ARB-L21-5000U is currently the most capacious link for powering flashlights, ensuring much longer work and constant current efficiency.
Thanks to the advanced design and multi-level security measures, the manufacturer guarantees up to 500 charging cycles with up to 75% capacity. This means that the cell can be discharged and recharged every day within 1.5 years, which clearly emphasizes its quality and efficiency. Due to the lack of memory effect, Fenix batteries can be recharged at any time without adversely affecting their capacity and lifetime.
The steel body ensures high mechanical strength and minimizes the risk of short circuits caused by falling or impact. Pressure vents are used in the battery, responsible for expelling gas which, during an incidental short circuit, may lead to rupture or explosion. The battery has an innovative charging system in the form of a built-in USB-C port. This extremely practical and convenient solution allows you to charge the cell without the need for an additional charger.
For charging, you only need a standard USB-C cable and a power source, eg a power bank, laptop, desktop computer or car USB charger.
The USB rechargeable battery allows you not only to save money (when buying a charger), but also provides comfort and mobility for charging. The manufacturer has applied a multi-level protection system which maximizes the lifetime of the battery and ensures the highest level of safety of the battery.
Security systems:
• protection against excessive discharge during use
• protection against overcharging during the charging process
• circuit protection against short circuits
• overheating protection
• cathode with PTC protection (overload protection)
To maximize the lifetime of the battery, it is recommended to charge it with a charger with a current of 1 A, maximum 5 A. • battery type: ARB-L21 21700 lithium-ion
• capacity: 5000 mAh
• voltage: 3.6 V
• maximum number of charging cycles: 500
• dimensions: 76 mm x 21.5 mm (hx φ)
• weight: 72.5 g
