  • Rechargeable & Long-Lasting: Supports multiple charge cycles with minimal degradation
  • Output Stability: Stable voltage curve during discharge ensures continuous power output
  • Compact 21700 Size: Universally compatible with a wide range of electronic devices
Applications
  • Aerospace: Provides lightweight, high-energy-density batteries for spacecraft, drones, UAV, and model aircraft
  • Robotics: Supplies continuous power for high-load robots
  • Lightweight Power Equipment: Assists with power for electric motorcycles, snowmobiles, electric bicycles, and other lightweight power tools
  • Power Tools: Delivers high burst power for drills, angle grinders, electric saws, blow dryers, and other high-current tools
  • Cleaning Appliances: Provides stable and lasting power for vacuum cleaners, mite removers, floor washers, steam mops, garden tools, and more, ensuring work efficiency and long battery life.
  • Medical Electronics: Provides highly reliable power for life monitors, portable medical devices, and more
Warning
  • Lithium-ion batteries require proper handling and knowledge to ensure safe operation
  • Failure to follow safety guidelines may result in fire, explosion, serious injury, or property damage
  • Only purchase and use if you fully understand lithium-ion battery safety
  • Never leave a battery unattended while charging
  • Keep away from animals and children
  • Prevent contact with metal objects (keys, coins, tools) to avoid short circuits
  • Inspect wraps and insulators regularly for damage - repair or dispose of damaged batteries immediately
  • Resellers must pass these warnings to customers
  • Typical cycle life of 200-500 cycles before noticeable capacity reduction - recycle at end of life
  • Do not crush, incinerate, or modify batteries
  • Only use within manufacturer specifications
