1. Wide Compatibility Designed for 4S5S battery packs, including LiFePO4, ternary polymer, and lithium titanate batteries. Supports 1.8V4.2V per cell and 60300Ah capacity for general applications. 2. Advanced Energy Transfer Uses flying capacitor technology to transfer energy between cells without external power. Leverages internal battery energy for efficiency balancing and extended battery lifespan. 3. Balancing Built with ultralow resistance MOSFETs and a 2 oz thick copper PCB. Delivers dynamic 05.5A balancing current with ≤5 mV accuracy for cell voltage uniformity. 4. Intelligent Sleep Mode Automatically enters hibernation when battery voltage drops below 2.7V. Reduces standby power consumption to <0.1 mA, helping to avoid overdischarge damage. Use scenarios Scenario 1: Balancing 4S5S packs in RC models, drones, or portable electronics that use LiFePO4, ternary polymer, or lithium titanate cells, ensuring consistent cell voltages during charging and discharge. Scenario 2: Maintaining balance in large 60300Ah energy storage systems to improve cycle life and reliability by preventing voltage drift between cells. Scenario 3: In field deployments or maintenance scenarios where external power is unavailable, the device uses battery energy to perform efficiency balancing and then conserves power with Intelligent Sleep Mode to minimize standby draw.
