Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Battery Management System (BMS): Manages 2S LiFePO4 batteries, ensuring safe charging/discharging cycles with overcurrent/overvoltage protection.
  • Power Regulation: Delivers stable 7.4V output for applications like refrigerator control, treadmill power supply, and LED lighting systems.
  • Multi-Device Compatibility: Designed for integration into refrigerators, power banks, treadmills, and industrial control panels.

Key features

  • 1. Advanced 4-Layer FR-4 PCB Construction

    • With a 4-layer FR-4 PCB design, achieve superior thermal management and signal integrity for reliable operation in high-power environments. Compared to 2-layer alternatives, this reduces heat buildup and enhances durability under continuous use*.

  • 2. Real-Time LED Status Monitoring

    • With integrated LED indicators, monitor battery voltage, charge/discharge status, and system alerts instantly. This eliminates the need for external diagnostics, saving time compared to non-LED-equipped controllers*.

  • 3. High-Current Handling Capacity

    • With a maximum 15A current rating, ensure stable power delivery for energy-intensive devices like refrigerators and treadmills. Outperforms lower-rated boards in maintaining consistent output under heavy loads*.

  • 4. Multi-Application Versatility

    • Designed for multi-scenario use, seamlessly integrates into refrigerators, power banks, and treadmills. This adaptability reduces the need for device-specific controllers, offering cost-effective flexibility*.

  • 5. EU Sustainability Compliance

    • Complies with German EPR packaging standards, ensuring eco-friendly disposal of packaging materials. This meets stricter EU environmental regulations than non-certified alternatives*.
