3.1. Built-in 200A Battery Management System (BMS)

The integrated 200A BMS provides critical protection features to ensure the battery's longevity and safe operation:

• Overcharge Protection: Prevents charging beyond the safe voltage limit.
• Over-discharge Protection: Stops discharge before the battery voltage drops too low.
• Overcurrent Protection: Safeguards against excessive current draw.
• Short Circuit Protection: Automatically disconnects in case of a short circuit.
• High/Low Temperature Protection: Manages operation within safe temperature ranges.

4. Setup and Installation

4.1. Unpacking and Initial Inspection

Upon receiving your battery, carefully inspect the packaging for any signs of damage. Remove the battery and check for physical damage, loose terminals, or leaks. If any issues are found, contact customer support immediately.

4.2. Physical Dimensions and Terminals

The battery features M8 bolt terminals for secure connections. Ensure all connections are tight and properly insulated.

4.3. Connection Guidelines

Connect the battery to your system using appropriate cables and connectors. Always connect the positive (+) terminal to the positive (+) terminal of your load/charger and the negative (-) terminal to the negative (-) terminal. Ensure all connections are clean and tight to prevent resistance and overheating.

For this 36V 100Ah battery, it is typically used as a single unit. If connecting multiple batteries for higher capacity or voltage (e.g., for other MOSEWORTH models), consult a qualified electrician and refer to specific wiring diagrams for series or parallel configurations.

5. Charging Instructions

The MOSEWORTH LiFePO4 battery supports multiple charging methods:

• Dedicated LiFePO4 Charger: Recommended for optimal charging.
• Solar Panel: Can be charged using a solar panel setup (e.g., ≥400W for a sunny day).
• Generator: Compatible with generators using a 20A DC-DC charger.

7. Maintenance and Storage

7.1. General Maintenance

LiFePO4 batteries require minimal maintenance. Periodically check terminal connections for tightness and cleanliness. Ensure the battery is kept in a dry, well-ventilated area.

7.2. Long Lifespan

This battery is designed for over 5000 deep cycles, providing more than 10 years of reliable service under normal operating conditions.

7.3. Storage

For long-term storage, charge the battery to approximately 50% State of Charge (SOC) and store it in a cool, dry place, ideally between 32°F (0°C) and 95°F (35°C). Avoid storing in direct sunlight or extreme temperatures.

8. Troubleshooting

If you encounter issues with your MOSEWORTH LiFePO4 battery, consider the following common checks:

• Battery Not Charging:
  • Verify charger compatibility and proper connection.
  • Check if the ambient temperature is below 32°F (0°C), which would prevent charging due to low-temperature protection.
  • Ensure the charger is functioning correctly.
• Battery Not Discharging/No Power Output:
  • Check all cable connections for tightness and correct polarity.
  • Verify if the battery is fully discharged (BMS will cut off power).
  • Check if the ambient temperature is below -4°F (-20°C) or above 140°F (60°C), triggering temperature protection.
  • Inspect for any short circuits in the load or wiring.
• Unusual Odor or Swelling: Immediately disconnect the battery and contact customer support. Do not attempt to use or charge the battery.

The built-in BMS is designed to prevent most common issues. If problems persist after these checks, please contact MOSEWORTH customer support.
