Battery Cell Specification

The biggest advantage of prismatic cells is its thin profile, lightweight, and the effective use of space. Due to the rectangle shape of these cells, it can facilitate better layering and increase flexibility in the products. With big capacity, less cell assembled together makes monitoring on each battery cell instead of cell string become possible. Changing defective battery cell is feasible too when there is cell failure.

Cell Dimensions

Cell Technical Data

• Intelligent factory design, high performance consistency;

• Square aluminum shell, high-precision explosion-proof valve, high safety performance;

• Low internal resistance, high discharge rate and stable discharge platform;

• Long cycle life, the capacity retention ratio exceeds 70% after 4000 cycle @ 0.5C/1C

Precautions

Precautions for Using the Hertz 1250 LiFePO4 Battery

To ensure the safe and efficient use of the Hertz 1250 LiFePO4 battery, it is important to follow certain precautions and guidelines. Here are the key measures to consider:

1. Avoid Overcharging and Over-discharging:

• Charging Cut-off Voltage: Ensure the charging voltage does not exceed 14.6V.

• Discharging Cut-off Voltage: Do not allow the battery voltage to drop below 10V during discharge.

2. Temperature Management:

• Charging Temperature Range: Charge the battery within the temperature range of 0~55℃ to avoid damage.

• Discharging Temperature Range: Discharge the battery within the temperature range of -20~60℃.

• Storage Temperature Range: Store the battery within the temperature range of -20~45℃.

3. Proper Handling and Installation:

• Handle the battery with care to avoid physical damage.

• Ensure proper installation and secure mounting to prevent vibrations or impacts.

4. Use Compatible Chargers:

• Use chargers specifically designed for LiFePO4 batteries to maintain optimal performance and safety.

5. Regular Monitoring:

• Regularly check the battery's voltage, capacity, and overall health.

• Utilize the optional LCD display and Bluetooth features for real-time monitoring.

6. Avoid Short Circuits:

• Prevent the battery terminals from coming into contact with conductive materials to avoid short circuits.

7. Waterproof Precautions:

• Although the battery is rated IP65, avoid submerging it in water. Ensure that the battery compartment or enclosure is sealed properly to protect against water ingress.

8. Cycle Life Management:

• To maximize the cycle life, avoid deep discharges. Keeping the Depth of Discharge (DOD) around 80% can significantly extend the battery's lifespan.

9. Use in Series and Parallel Configurations:

• When configuring batteries in series or parallel, ensure all batteries are at the same voltage level before connection.

• Use appropriate battery management systems (BMS) to balance and protect the batteries.

10. Inspection and Maintenance:

• Perform regular inspections for any signs of damage or wear.

• Clean the terminals and ensure they are free from corrosion.

11. Avoid Extreme Conditions:

• Do not expose the battery to direct sunlight or extreme heat for prolonged periods.

• Avoid using or storing the battery in extremely humid or corrosive environments.

By following these precautions, you can ensure the safe and effective operation of the Hertz 1250 LiFePO4 battery, maintaining its performance and extending its service life.
