Description

01. 21700 “i” series rechargeable battery
With a capacity of 5000mAh and a discharge current of 8A
02. The “I” series of 21700 batteries is a Revolutionary and Powerful upgrade (Patent No. ZL201820118916.0, US Patent pending)
– 21700i batteries are a patent product developed by NITECORE
– They allow high efficiency power supply by reducing losses from internal resistance
– It has a positive and negative pole on each side, as well as a high concentration of energy
– It is compatible with adaptive accessories of intelligent communication and control systems
03. Excellent energy density
21700i batteries have an energy density of up to 240mWh/g
11% more than 18650 batteries
The energy capacity calculation formula is:
Mass Energy Density = Battery Capacity x Battery Voltage / Total Battery Weight
* The energy density of a 18650 Li-ion battery is: 216mWh/g (3500mAh, 3.7V)
* Total weight of one NL2150i is 75.5g
04. Battery performance is unprecedented
The dual polarity on both sides of the 21700i series batteries broke the rule of
connecting the head and rear switch so as to reduce the size and weight of the lens.
Thus the internal resistance is dramatically reduced to offer direct conversion of energy for the supply of the device. Because of the innovative techniques and technology our lenses have the ability to design with more features.
05. Internal security features
– Innovative anode design with high temperature resistance
– The pressure relief valve is activated in the event of a rapid increase in temperature
– A built-in PTC circuit limits surges
– Microporous protector protects sensitive internal component
06. High efficiency electronic protection circuit
1. It automatically protects against over-charging, over-discharging and short-circuiting
2. It incorporates a high-quality integrated protection circuit
3. It incorporates two very powerful MOSFETs in the current regulation unit for excellent performance
07. External safety features
1. Fitted at both ends with nickel-plated steel strips to ensure impact resistance
good electrical contact and oxidation resistance
2. Coated with durable metal film to protect against corrosion
3. Durable plastic protector of the electronic circuit
08. Low cost and Environmentally friendly
By using Li-ion rechargeable batteries you save energy and reduce it carbon footprint on the planet
09. Safety and reliability
Globally insured and approved with many international certificates
10. Technical characteristics:
– Type: NL2150i
– Capacity: 5000mAh
– Voltage: 3.6V
– Continuous discharge current: 8A Max
– Weight approx: 75.5 g
– Total length: 76.7mm +/- 0.3mm
– Diameter: 21.9mm +/- 0.3mm
– Warranty period: 12 months from the date of purchase
