Rechargeable battery 21700 5000 mAh s USB-C (Li-Ion) - Fenix

Rechargeable battery 21700 5000 mAh s USB-C (Li-Ion) - Fenix 

with a capacity of 5000 mAh designed mainly for high-performance flashlights. Thanks to its integrated USB-C port, the battery can be charged directly using a cable connected to a computer, power bank or wall charger. It can also be charged using standard Li-ion chargers designed for 21700 batteries.

The battery uses advanced LiNiCoO2 technology, which ensures high capacity, stable performance and long service life. Li-ion cells do not suffer from memory effect and have very low self-discharge, making them ideal for modern flashlights and electronic devices.

The battery features integrated protection electronics that prevent overcharging, over-discharging, short circuits and excessive current draw. Internal safety mechanisms include a PTC thermal protection system, an electrode separator and a pressure relief valve that safely releases excess gas if needed.

This battery is compatible with several Fenix flashlights including HT18, PD36R, PD36 TAC, PD40R, TK20R V2.0, TK22 UE, E35 V3.0 and C7. Due to its larger size it cannot be used in flashlights designed for 18650 batteries.
