Fenix USB Battery ARB-L21U (21700 5000 mAh 3.6

Product description

TheFenix ARB-L21-5000U is a high-quality 21700 type lithium-ion battery with an impressive capacity of 5000 mAh equipped with an innovative USB-C charging system.

Reliability and performance

The ARB-L21-5000U is currently the highest capacity flashlight power cell, providing significantly longer operation and consistent current output.

Thanks to its advanced design and multi-level protection, 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 over a period of 1.5 years - which clearly emphasizes its quality and performance. Due to the lack of memory effect, Fenix batteries can be recharged at any time without adversely affecting their capacity and service life.

The steel body provides high mechanical strength and minimizes the risk of short-circuiting caused by a fall or impact. The battery uses pressurized vents responsible for expelling gas, which can lead to a bloat or explosion during an incidental short circuit.

Fast USB-C charging

The battery uses an innovative charging system in the form of a built-in USB-C port. This extremely practical and convenient solution makes it possible to charge the cell without the need for an additional charger.

All you need to charge it is a standard USB-C cable and a power source, such as a power bank, laptop, desktop computer or car USB charger.

The USB battery pack not only saves money (on the purchase of a charger), it provides, above all, the convenience and mobility of charging.

Advanced security features

The manufacturer has used a multi-level security system to maximize the life and ensure the highest level of safety of the battery.

Safety systems:

  • Over-discharge protection during use
  • protection against overcharging during the charging process
  • circuit protection against short circuits
  • protection against overheating
  • cathode with PTC protection (overload protection)

.To maximize the life of the battery, it is recommended to use a charger with a current of 1 A for charging, with a maximum of 5 A.
