Product Technical Details Product Interface

Main Characteristics

  • Humanized Design: Automatic, intelligent, and logical design. Small, light, noiseless, and easy to transport.
  • High Efficiency: Efficiency above 87%, saving approximately 30% power per charge.
  • Superior Charging Effect: Multi-stage constant current and voltage. Pulse charging protects battery life and prevents overcharging.
  • Safe & Intelligent: Includes short circuit protection, over-temperature protection, and real-time state display. Stops automatically when charging is complete.

Working Principle & Procedure

This charger adopts Iu-Ia charging curves with programmable intelligent control to ensure the battery reaches an excellent state and prolongs its service life.

1
Charge with maximum current until the set voltage value is reached.
2
Constant voltage charging where current value decreases to the set threshold.
3
Constant current charging until the next stage.
4
Secondary constant voltage charging with further current reduction.
5
Constant current charging until the cycle is complete.
Safety Features
  • Working Time: Standard 8-11 hours depending on capacity and discharge level.
  • Low Voltage Protection: Refuses to charge if battery voltage is below the minimum safety threshold.
  • Overvoltage & Overcurrent Protection: Prevents damage from abnormal electrical values.
  • Overheat Protection: Automatically shuts down or restricts operation if internal temperatures are too high.
  • Equalization Charging: Runs automatically after every 15 cycle charges to balance battery cells.
