  • Revolutionary and Powerfully Upgraded (21700 i Series Batter): 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
  • Outstanding Energy Density: A 21700 i Series Battery has an energy density of up to 240mWh/g, 11% higher than 18650 batteries
  • 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.Thanks to the groundbreaking technology and techniques, this can bring more possibilities to our flashlight design
  • Ideal for high drain devices: Max 15A continuous discharge current
  • Internal Safety Features
    • Pressure relief valve activates in the event of a rapid temperature increase
    • Innovative anode design with high temperature resistance
    • Microporous barrier protects delicate internal components
    • Built-in PTC to inhibit high current surges
  • High-performance Protective Circuit
    • Automatically protects against overcharge, over discharge and short-circuiting
    • Utilizes a high-quality battery protection IC
    • Utilizes two high-power MOS FETs in the current regulation module for better efficiency and superior output
  • External Safely Features
    • Equipped at both ends with a nickel-plated stainless steel protector ensuring high impact resistance, good electrical conductivity and oxidation resistance
    • Coated with durable metallic film to guard against abrasion
    • Tough plastic circuit board protector
  • Low Cost and Environmentally Friendly: Using a rechargeable Li-ion battery is energy saving to minimize the carbon footprint
