Fenix ARB-L21-5000 V.2 is a 21700 type high-current lithium-ion battery with an impressive capacity of 5000 mAh equipped with an advanced protection system.
The ARB-L21-5000 is currently the highest capacity flashlight power cell, providing significantly longer operation and consistent current output.
Thanks to the 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 negative impact on their capacity and 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 that can lead to a bloat or explosion during an incidental short circuit.
The manufacturer has used a multi-level safety system that maximizes the life and ensures the highest level of safety of the battery.
Safety systems:
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. Maximum discharge current of 7.5 A.
