The Seplos S-10A-B Active Balance Board is designed to reduce voltage differences between individual cells in LiFePO4 battery packs. The balancer draws energy from the battery pack and redistributes balancing current to help maintain more consistent cell voltages during standby, charging and discharging.
The board can operate independently or work together with Seplos BMS 3.0. When the cell voltage difference reaches the configured threshold, the BMS can send a control signal through its dry contact to activate balancing automatically. Built-in voltage and temperature protection helps prevent balancing under unsuitable battery conditions.
10A Active Balancing
High-current active balancing helps reduce cell voltage differences and maintain better consistency across LiFePO4 battery packs.
Automatic Voltage Control
Balancing starts when cell voltage difference exceeds 50mV and stops after the difference falls below 30mV.
BMS 3.0 Integration
Supports automatic activation through the Seplos BMS 3.0 dry-contact interface while also allowing standalone operation.
Voltage & Temperature Protection
Built-in overvoltage, undervoltage and over-temperature protection helps prevent balancing under abnormal battery conditions.
Review the key electrical, environmental and communication parameters before confirming battery configuration and system compatibility.
Use these values for preliminary battery pack, inverter and current matching before final technical confirmation.
