4. Setup and Installation

Before connecting the battery, ensure all components are present and undamaged. Always wear appropriate personal protective equipment (PPE) such as gloves and eye protection.

4.1 Initial Inspection

• Unpack the battery and inspect for any physical damage.
• Verify that the package includes the battery and M8 bolts for connection.

4.2 Connecting the Battery

Connect the battery using the provided M8 bolts. Ensure all connections are tight and secure to prevent arcing and ensure optimal performance.

• Single Battery Connection: Connect the positive terminal to the positive load/charger and the negative terminal to the negative load/charger.
• Series Connection (for higher voltage): Up to 4 batteries can be connected in series to achieve a 48V system. Connect the positive terminal of one battery to the negative terminal of the next.
• Parallel Connection (for higher capacity): An unlimited number of batteries can be connected in parallel. Connect positive terminals together and negative terminals together.

For marine applications, it is highly recommended to install the battery within a waterproof battery box to protect it from moisture and environmental elements.

5. Operating Instructions

5.1 Bluetooth App Usage

Download the MOSEWORTH Bluetooth application from your smartphone's app store (available on App Store and Google Play). Once installed, open the app and allow it to connect to your battery. The app will display real-time data including:

• Battery Voltage

6. Charging Methods

The MOSEWORTH LiFePO4 battery can be charged using several methods. For optimal performance and longevity, it is recommended to charge the 12V LiFePO4 battery at a voltage of 14.6V.

6.1 Recommended Charging Sources

• LiFePO4 Charger: Use a dedicated 14.6V LiFePO4 charger (recommended 20A-50A). This method offers the fastest charging, achieving a full charge in approximately 2 hours with a 600W solar setup or equivalent charger.
• Solar Panel: Connect to a solar panel system (recommended >300W) with a compatible MPPT or PWM solar charge controller.
• Generator/Alternator: Can be charged via a generator or vehicle alternator with an appropriate DC-DC charger or inverter with charging function.

6.2 Charging Precautions

• Ensure the charger is compatible with LiFePO4 batteries. Using a charger designed for lead-acid batteries may damage the LiFePO4 battery.
• Do not charge the battery if its internal temperature is below 32°F (0°C). The BMS will prevent charging in these conditions.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your MOSEWORTH LiFePO4 battery.

• Regular Monitoring: Use the Bluetooth app to regularly check battery status, especially voltage and temperature.
• Recharge After Full Discharge: If the battery is fully discharged, recharge it within 12 hours to maintain optimal performance and prevent potential long-term damage.
• Terminal Inspection: Periodically check battery terminals for corrosion or loose connections. Clean as necessary and ensure connections are tight.
• Storage: For long-term storage, store the battery in a cool, dry place with a State of Charge (SOC) between 50% and 80%. Avoid storing in direct sunlight or extreme temperatures.
• Environmental Protection: As mentioned, for wet or marine environments, always use a waterproof battery compartment.

8. Troubleshooting

If you encounter issues with your MOSEWORTH LiFePO4 battery, refer to the following common troubleshooting steps:

• Battery Not Charging:
  • Check charger compatibility and ensure it's a LiFePO4 specific charger.
