NL2150HPI - NITECORE 21700i RECHARGEABLE BATTERY 3.6V 5000MAH

NL2150HPi: Revolutionary and Powerfully Upgraded
21700 i Series Battery (Patent No.ZL201820118916.0, US Patent Pending)

As a patent product developed by NITECORE, the 21700 i Series Battery is a proprietary 21700 rechargeable Li-ion battery featuring dual way output with positive and negative polarities at both ends and a high energy density. It enables a highly efficient output by minimizing the loss of power due to internal resistance.

Unprecedented Battery Performance

The dual polarities of the 21700 i Series Battery at both ends have broken the convention of linking the head and the tail of the flashlight in order to minimize its size and weight. The internal resistance is therefore greatly reduced to offer a direct energy conversion to power the device.

Internal Safety Features

- Pressure relief valve activates in the event of a rapid temperature increase
- Microporous barrier protects delicate internal components
- Innovation anode design with high temperature resistance
- Built-in PTC inhibit high current surges

External Safety Features

- Equipped at both ends with nickel-plated steel strips ensuring high impact resistance, good electrical conductivity and oxidation resistance
- Coated with durable metallic film to guard against abrasion
- Tough plastic circuit board protector

High-performance Protective Circuit

- Automatically protects against overcharge, overdischarge and short-cicuiting
- Utilizes a high-quality battery protection IC
- Utilizes two high-power MOS FETs in the current regulation module for better efficiency and superior output
