Nitecore NL2150i Rechargeable 21700 Battery

Rechargeable 21700 battery Nitecore NL2150i of the "i" series, with a capacity of 5000mAh and a discharge current of 8A.

The "I" series of 21700 batteries is a revolutionary and powerful upgrade. 21700i batteries are a patent product developed by Nitecore. They enable high efficiency power supply, by reducing internal resistance losses. They have a positive and negative pole on each side, as well as a high concentration of energy. They are compatible with adaptive accessories of intelligent communication and control systems.

Nitecore NL2150i batteries have an energy density that reaches up to 240mWh/g, 11% more than 18650 batteries.

The dual polarity on both sides of the 21700i series batteries, broke the rule of connecting the head with the tail switch. This has reduce the size and weight of the flashlight and that is why the internal resistance is dramatically reduced to offer direct conversion of energy to supply the device.

NL2150i rechargeable batteries have innovative internal safety features.

The high-performance electronic protection circuit automatically protects against over-charging, over-discharging and short-circuiting.

In addition, it incorporates a high-quality integrated protection circuit as well as two very powerful MOSFETs in the current regulation unit for better performance.
