IV. Product Advantages
Efficient Energy Management with Active Balancing
Unlike passive balancers, the active balancing technology transfers energy between cells to eliminate voltage differences without wasting capacity. This boosts battery usage efficiency to 95%, extending the battery pack’s runtime and overall lifespan.Comprehensive Safety Protection
Equipped with multi-layer safeguards against overcharging, over-discharging, over-current, short circuits, and over-temperature. These protections are critical for preventing battery damage and ensuring safe operation in various scenarios.Precision Monitoring and Clear Power Status
Measures individual cell voltages (1V - 5V) with ±5mV accuracy, ensuring accurate cell performance tracking.
Features a built-in coulomb meter that displays real-time remaining capacity, eliminating guesswork about remaining power.
Convenient Connectivity and Remote Control
Supports Bluetooth connectivity, which syncs with a mobile app to show live battery status (voltage, current, temperature, balance progress). This allows users to check stats anytime and anywhere via their phones. Additionally, it offers RS485, CANbus, and UART communication for flexible monitoring options.Wide Compatibility for Versatile Use
Supports 8S - 24S battery configurations (24V - 96V) and discharge currents from 40A to 500A, making it suitable for both small-scale DIY projects and high-power systems (e.g., RV battery banks, off-grid setups).Customization and Accessibility
Offers customization services to tailor solutions for specific battery packs, meeting personalized needs.
Low MOQ (1pc) allows individual users or small-scale projects to purchase easily.
CE certification ensures compliance with relevant quality and safety standards.
