DALY BMS LFP 08S/40A Same Port W/P Battery

The DALY BMS LFP 08S/40A Same Port W/P Battery is a Battery Management System (BMS) specifically designed for Lithium Iron Phosphate (LiFePO4) battery packs. This BMS ensures the safe and efficient operation of the battery by monitoring key parameters such as voltage, current, temperature, and state of charge (SOC). Here’s a detailed description of the model:

Key Features:

1. Battery Type Compatibility:
   • LiFePO4 (LFP): This BMS is designed for Lithium Iron Phosphate (LiFePO4) batteries, a safe, long-life, and stable lithium battery chemistry. LiFePO4 batteries are popular for energy storage, electric vehicles, and other high-performance applications due to their safety and long cycle life.
2. Battery Series:
   • 08S: The “08S” indicates that this BMS is intended for an 8-series (8S) LiFePO4 battery configuration, meaning it is designed to work with a battery pack consisting of 8 individual battery cells connected in series.
   • In a typical 8S LiFePO4 pack, the nominal voltage would be around 25.6V (3.2V per cell × 8), with a full charge voltage around 29.6V (3.7V per cell × 8).
3. Current Rating:
   • 40A Continuous: This BMS can handle 40A of continuous current, which is suitable for moderate to high-power applications, such as solar energy storage, small electric vehicles, or power tools.
   • Peak Current: It is also capable of handling peak currents higher than the continuous rating, often up to 100A for short durations, depending on the specific BMS design and protection features.
4. Same Port W/P (With Protection):
   • Same Port: This suggests that the BMS uses a single port for both the charge and discharge connections, simplifying wiring and installation in the battery pack. Typically, BMS systems may have separate ports for charging and discharging, but this one combines them into a single interface for ease of use.
   • W/P stands for With Protection, meaning the BMS includes built-in protection features to safeguard the battery pack from potential damage during operation.
5. Protection Features: The DALY BMS is equipped with several protective features to ensure the longevity and safety of the LiFePO4 battery pack:
   • Over-voltage Protection: Prevents the battery cells from being charged above their maximum safe voltage (usually around 3.65V per cell).
   • Under-voltage Protection: Ensures the battery is not discharged below its safe voltage level (usually around 2.5V per cell).
   • Over-current Protection: Limits the current flowing through the battery pack to protect the cells from excessive charge or discharge currents.
   • Over-temperature Protection: Protects the cells from damage due to high temperatures, ensuring that the battery does not overheat during charging or discharging.
   • Short-circuit Protection: Automatically cuts off the power in case of a short circuit to prevent damage to the battery and BMS.
