Top binned CREE XP-G S2 LED

Ultra-high voltage underload. Protruded button top.
Measures only 68.5mm in height!


Ultra-high capacity

These 18650 cells offer ultra-high capacity at 2500mAh, and maintain highest voltage underload, making single 18650 li-ion flashlight regulate longer and better.

Only 68.5mm in height

Protected 2500mAh 18650 li-ion with only 68.5mm in height. That makes it highly compatible with all 18650 flashlights and chargers in the market.

Button top design

The protruded button top design makes it work with any flashlight that uses hardware anti-reversed battery polarity protection. It also ensure good conductivity when multiple batteries are used in series.


  • Battery cells made using Korean technology
  • Nickel plated steel button top
  • IC protected against short, over-discharge, over-charge
  • Measures only 68.5mm in height
  • Button top design
  • Steel plate reinfocred bottom
  • Ultra high capacity and high voltage even under heavy loading
  • Safety vent with thermal cut-off protection

  • Specifications:
  • Voltage: Typical 3.6V (4.2V when fully charged)
  • Capacity: 2500mAh (discharged at 0.2C)
  • Dimensions: 18.6mm x 68.5mm (+/-0.1mm)
  • Current over-flow protection: 5A-6A
  • Weight: 50gram

  • High voltage and capacity

    Our 2500mAh cells give the highest voltage underload, making it ideal to use in single li-ion flashlight application where flat regulation and high output are required. These cells also maintain very high capacity under high current load.

    High consistency

    ET 2500mA batteries, when discharged at 2A and 5A,it yields 2464mAh and 2376mAh capacity respectively. When discharged at lower current like 0.2C, it yields full 2500mAh capacity.
