NITECORE BATTERY 21700 / 5000mAh (price per piece)

Description

NITECORE 21700 / 5000mAh BATTERY (price per unit)
A new generation of rechargeable Lithium Ion (Li-ion) battery for longer life, strong performance, high intensity!
21700 batteries first appeared in the electric car industry and are expected to dominate as the next cylindrical batteries worldwide.
They feature an innovative anode design with high temperature resistance, a pressure relief valve in the event of rapid temperature increase, built-in PTC rings to inhibit high-load surges, a protective microporous barrier protects sensitive internal components.
It has a built-in, high-performance electronic protection circuit that:
1. Automatically protects against overcharging, overdischarging and short circuit.
2. Integrates a high-performance battery protection chip
3. Integrates two high-power semiconductors in the current regulation unit for better performance and excellent current output.

Its external safety features are:
1. It is equipped on both sides with nickel-plated steel protectors that ensure impact resistance, good electrical conductivity and protection against oxidation.
2. It is wrapped with a durable metal film that protects against abrasion.
3. Hard plastic protector for the electronic circuit.

It offers low operating costs and is environmentally friendly
By using a rechargeable lithium-ion battery, you contribute to reducing your carbon footprint.
