The Wuben 21700 battery with a capacity of 4800 mAh is based on cutting-edge technology that ensures a longer service life and higher safety. The service life is more than 500 charging cycles. The battery is equipped with protection against deep discharge, overcharge, short circuit, and overheating.
The advantage of a Li-Ion battery is its high capacity; in addition, it hardly suffers from self-discharge or memory effect. This model is an excellent choice because, despite its size and weight, it can store a huge amount of energy.
This battery is not intended only for Wuben flashlights and can be used with any other flashlight. Note that due to its larger dimensions, it cannot be used with flashlights designed for 18650 batteries.
This R version is additionally equipped with a built-in micro-USB-C port, which allows charging without the need for a charger.
