DALY LFP 8S 60A 3.6V BMS, Lithium Battery

The DALY LFP 8S 60A 3.6V BMS is a Battery Management System (BMS) designed for lithium iron phosphate (LiFePO4) batteries. Here’s a detailed description of its features and specifications:

1. Battery Configuration:
   • 8S: This indicates that the BMS is designed for an 8-series battery pack, meaning it can manage a total of 8 individual cells connected in series, providing a nominal voltage of around 25.2V (3.6V per cell).
   • 3.6V per Cell: This is the nominal voltage for LiFePO4 cells. Full charge voltage is around 3.65V per cell.
2. Current Rating:
   • 60A Continuous: The BMS is capable of handling a continuous discharge current of up to 60A, which is suitable for mid-range power applications like electric bikes, solar systems, and other energy storage solutions.
   • Peak Current: It can usually handle higher surge currents for short durations (typically 2-3 times the continuous rating), but specific peak current values depend on the model.
3. Protection Features:
   The DALY LFP BMS includes built-in protection features to ensure safe operation of the lithium battery pack:
   • Overcharge Protection: Prevents the battery from charging beyond the safe voltage limit, typically 3.65V per cell.
   • Overdischarge Protection: Cuts off the battery when the voltage of a cell drops too low, typically around 2.5V to 2.8V.
   • Overcurrent Protection: Protects the battery and circuit by disconnecting if a current higher than the rated value is drawn.
   • Short-circuit Protection: If a short circuit is detected, the BMS will disconnect the load to prevent damage.
   • Temperature Protection: Monitors the temperature of the cells and will disconnect the battery if it exceeds safe limits.
4. Balancing Function:
   • Cell Balancing: Ensures all cells in the battery pack are at the same voltage, preventing overcharging or undercharging of individual cells. This feature is essential for maximizing the lifespan and efficiency of the battery.
5. Communication:
   • CAN Bus or UART Communication: Some versions of the DALY LFP BMS include communication interfaces like CAN Bus or UART, allowing for integration with battery management systems, monitoring systems, and other smart devices.
   • State-of-Charge (SOC) Monitoring: Many models also feature voltage-based SOC estimation to keep track of the battery’s remaining charge.
6. Applications:
   The DALY LFP 8S 60A BMS is suitable for use in various applications, such as:
   • Electric Vehicles (EVs): Including electric bikes, scooters, and small electric cars.
   • Energy Storage Systems (ESS): For off-grid solar energy storage.
   • Portable Power Stations: Used in solar-powered or battery-based power stations for camping and other applications.

In summary, the DALY LFP 8S 60A BMS is a robust and feature-rich solution designed to manage and protect lithium iron phosphate batteries in various energy storage and electric mobility applications.
