Description
Rechargeable Lithium Ion (Li-ion) battery size 21700 large capacity 5000mAh and high discharge rate 15A
– Compatible with accessories the “21700 Intelligent Battery System”
– Compatible with the i4000R lens
Revolutionary and Dynamically Upgraded
“I” series of batteries 21700
(Patent No.ZL201820118916.0)
As a patented product developed by NITECORE, the 21700i series is a rechargeable lithium-ion battery characterized by a dual-mode power output with positive and negative polarity at both ends and a high energy density. It enables a highly efficient performance by minimizing power loss due to internal resistance.
Excellent energy density.
21700i series batteries have an energy density above 240 mWh / g,
11% higher than 18650 batteries
Unprecedented battery performance
The dual polarity of the 21700i series of batteries at both ends breaks the contract of connecting the head and tail of the lens in order to reduce its size and weight.
Thus the internal resistance is greatly reduced to provide an immediate energy change for the supply of the device. Due to innovative technology and techniques more design options are offered.
It is ideal for devices that require continuous high discharge current of 15A
Below some security features in the structure of the structure of the battery
– Innovative design the anode with high temperature resistance
– pressure relief valve which is actuated in the event of a rapid increase in temperature
– Internal protection circuit ( PTC) to inhibit large currents.
– Exterior cover with micropores protects sensitive internal components
High-performance electronic protection circuit
– Automatically protects against overcharging, over-discharging and short
– circuiting – Incorporates a high-quality electronic battery protection circuit
– Incorporates two powerful MOSFETs in the current control unit for better performance and excellent current.
Below are some external safety features
– It is equipped at both ends with nickel-plated stainless steel protectors that ensure high impact resistance, good electrical
conductivity and oxidation resistance.
– Coated with durable metal film for abrasion protection
– Durable plastic protector of the electronic board.
Low energy costs and environmentally friendly
Using rechargeable batteries is more economical and at the same time helps to reduce the carbon footprint on the planet.
Safe and Reliable
It is insured worldwide as well as is approved according to many international standards.
