Junsi iCharger 4010DUO DC Battery Charger features:

  • High-Performance Technology: The 4010DUO employs advanced synchronous buck-boost DC/DC converter technology, delivering an impressive 2000W of charging power. With a maximum charge/discharge current of up to 40A per channel (or up to 70A in Synchronous Mode), it’s well-equipped for demanding battery charging tasks.
  • Versatile Battery Compatibility: Each channel supports 10S lithium batteries, making it suitable for various applications.
  • Informative TFT LCD Screen: The TFT LCD screen provides critical battery information, including current, voltage, power, capacity, internal resistance, control status, time, and temperature.
  • Parameter Storage: Save up to 64 parameter sets without repeating settings, thanks to easy import/export via an SD card.
  • Internal Resistance Correction: The 4010DUO features a unique “internal resistance correction” balance calculation, ensuring accurate battery balancing.
  • Discharge Features: Choose from various discharge modes, including discharge-self, regenerative to input discharge, regenerative to channel discharge, and lithium battery extra expanding discharge.
  • Individual Cell Measurement: Not only can it measure the internal resistance of the entire battery pack, but it can also assess the internal resistance of individual cells within the battery.
  • Temperature Protection: Internal temperature protection ensures safe and efficient operation. If the temperature exceeds the threshold, the output power is automatically reduced, and the charger shuts down when it surpasses the cut-temperature.
  • Intelligent Fan Control: The charger senses internal temperature and adjusts the fan speed accordingly.
  • Comprehensive Protection: The 4010DUO safeguards against reversed polarity (input or output), input voltage/current issues, battery temperature, charging capacity, time overrun, and maximum power.
  • Firmware Upgrades: Easily update the hardware program via the USB port.
  • Logview Software Support: Use the “Logview” software to display, plot, and analyze charge and discharge data.

With its robust features, the 4010DUO is a reliable choice for battery enthusiasts and professionals alike.
