4. Setup
4.1 Unpacking and Inspection
Upon receiving your battery, carefully unpack it and inspect for any signs of damage. If damage is found, contact customer support immediately.
4.2 Installation
The yeagulch LiFePO4 battery is designed for flexible installation. It can be installed upright or sideways to fit into narrow spaces. Ensure the battery is secured to prevent movement during operation.
- Mounting: Secure the battery in a dry, well-ventilated area. Avoid direct sunlight or extreme temperatures.
- Orientation: The battery can be installed on its side. Do not invert the battery.
- Clearance: Allow sufficient space around the battery for air circulation and ease of access for connections.

4.3 Wiring Connections
Connect the battery to your system using appropriate cables and connectors. Ensure correct polarity (positive to positive, negative to negative). The battery comes with M8 terminal bolts.
- Single Battery Connection: Connect the positive terminal to the positive input of your load/charger and the negative terminal to the negative input.
- Series Connection: For higher voltage systems, up to 4 batteries can be connected in series (maximum 4S). Connect the positive terminal of one battery to the negative terminal of the next.
- Parallel Connection: For higher capacity, up to 4 batteries can be connected in parallel (maximum 4P). Connect positive terminals together and negative terminals together.
- Combined Series-Parallel: A maximum configuration of 4 series and 4 parallel (4S4P) is supported to create a 51.2V system or increase capacity.
- Always use appropriate fuses and circuit breakers for your system to protect against overcurrent.
5. Operating Instructions
5.1 Charging
The yeagulch LiFePO4 battery supports two primary charging modes:
- LiFePO4 Charger: Use a dedicated LiFePO4 compatible charger with appropriate voltage and current settings.
- Solar Panel + MPPT Controller: Connect to a solar panel system with a Maximum Power Point Tracking (MPPT) charge controller optimized for LiFePO4 batteries.
The built-in BMS will manage the charging process, including low and high-temperature cut-offs. Ensure charging occurs within the recommended temperature range of 0°C to 65°C (32°F to 149°F).
5.2 Discharging
The battery is designed for deep cycle applications. The BMS protects against over-discharging. The recommended discharge temperature range is -20°C to 70°C (-4°F to 158°F).

6. Maintenance
- Regular Inspection: Periodically check battery terminals for corrosion and ensure connections are tight.
- Cleaning: Keep the battery clean and free of dust and debris. Use a dry cloth for cleaning.
- Storage: If the battery will not be used for an extended period, charge/discharge it once every 6 months to prevent damage from disuse. Store in a cool, dry place.
- Temperature: Avoid exposing the battery to extreme temperatures outside its operating range.
7. Troubleshooting
If you encounter issues with your battery, refer to the following common troubleshooting steps:
- Battery Not Charging:
- Check all cable connections for proper seating and polarity.
- Verify the charger is compatible with LiFePO4 batteries and is functioning correctly.
- Ensure the ambient temperature is within the charging range (0°C to 65°C / 32°F to 149°F). The BMS may have initiated a low-temperature cut-off.
- Inspect fuses and circuit breakers in your system.
- Low Power Output:
- Check the battery's State of Charge (SOC). Recharge if necessary.
- Ensure the load is not exceeding the battery's continuous discharge current rating (100A). The BMS may have activated overcurrent protection.
- Verify all connections are secure and free of corrosion, which can increase resistance.
- Battery Overheating:
- Ensure adequate ventilation around the battery.
- Reduce the load if it is consistently high.
- The BMS will initiate a high-temperature cut-off if the internal temperature exceeds safe limits. Allow the battery to cool down.
If problems persist after following these steps, please contact customer support.
