3. Setup and Installation

3.1 Unboxing and Inspection

Upon receiving your DATOUBOSS LiFePO4 battery, carefully unbox it and inspect for any signs of damage. Ensure all included accessories, such as terminal bolts, are present.

3.2 Connecting Batteries (Series/Parallel)

The DATOUBOSS 12V 100Ah LiFePO4 Battery can be connected in series or parallel to achieve higher voltage or capacity. Always ensure all batteries are at a similar state of charge before connecting them.

• Parallel Connection (Increased Capacity): Connect positive terminals together and negative terminals together. This increases the total Ah capacity while maintaining 12V. For example, four 12V 100Ah batteries in parallel create a 12V 400Ah system.
• Series Connection (Increased Voltage): Connect the positive terminal of one battery to the negative terminal of the next. This increases the total voltage while maintaining 100Ah. For example, four 12V 100Ah batteries in series create a 48V 100Ah system.
• Maximum Expansion: The battery supports up to 4P4S configuration, allowing for a 48V (51.2V) 400Ah Li-Ion battery pack, delivering up to 20.48kWh energy.

4. Operating Instructions

4.1 Charging the Battery

The DATOUBOSS LiFePO4 battery can be charged using various methods:

• LiFePO4 Charger: Use a dedicated LiFePO4 charger with a voltage range suitable for 12V lithium batteries (typically 14.4V-14.6V). A 20A charger can fully charge the battery in approximately 5 hours.
• Solar Panels: Connect to a solar charge controller (MPPT or PWM) compatible with LiFePO4 batteries. Ensure your solar panel array provides sufficient wattage (e.g., >400W on a sunny day) for efficient charging.
• Generator: A DC-DC charger connected to a generator can also be used. A 20A DC-DC charger can charge the battery in approximately 5 hours.

5. Maintenance

The DATOUBOSS LiFePO4 battery is designed for minimal maintenance due to its robust construction and integrated BMS. However, following these guidelines will help ensure optimal performance and longevity:

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary and ensure they are tightened securely.
• Keep Clean: Keep the battery surface clean and dry.
• Temperature Management: While the battery has a wide operating temperature range, prolonged exposure to extreme heat or cold can affect performance and lifespan. Store the battery in a cool, dry place when not in use.
• Storage: For long-term storage, charge the battery to approximately 50% state of charge and disconnect it from any loads or chargers. Recharge every 3-6 months to prevent deep discharge.
• Avoid Deep Discharge: The BMS protects against deep discharge, but it is good practice to avoid consistently running the battery to its minimum voltage.

6. Troubleshooting

If you encounter issues with your DATOUBOSS LiFePO4 battery, consider the following common troubleshooting steps:

• Battery Not Charging:
  • Verify the charger is specifically designed for LiFePO4 batteries and is functioning correctly.
  • Check all cable connections for tightness and proper polarity.
  • Ensure the battery temperature is within the acceptable charging range. The BMS may prevent charging if the temperature is too low or too high.
• Low Voltage Output:
  • Check the battery's state of charge. The battery may need recharging.
  • Inspect connections for corrosion or looseness, which can cause voltage drops.
  • Ensure the load is not exceeding the battery's maximum continuous discharge current (120A). The BMS will disconnect the battery if overloaded.
• BMS Disconnection (No Output):
  • A BMS disconnection indicates a protection event (e.g., overcharge, over-discharge, overcurrent, short circuit, or temperature extreme).
  • Remove the load or charger, allow the battery to rest, and then attempt to reconnect. The BMS typically resets automatically once the fault condition is removed.
  • If a short circuit occurred, inspect cables and devices for damage before reconnecting.
• Unusual Odor or Swelling:
  • Immediately disconnect the battery from all loads and chargers.
  • Move the battery to a safe, well-ventilated area away from flammable materials.
  • Do not attempt to use or repair the battery. Contact DATOUBOSS customer support for assistance.
