5. Setup and Installation

5.1 Initial Inspection

Before installation, inspect the battery for any visible damage. Ensure terminals are clean and free of debris.

5.2 Connection Guidelines

1. Ensure all power sources are disconnected before making any connections.
2. Connect the positive (+) terminal of the battery to the positive (+) terminal of your system.
3. Connect the negative (-) terminal of the battery to the negative (-) terminal of your system.
4. Use the provided M8 studs and insulating caps to secure connections firmly. Loose connections can cause overheating and damage.
5. This battery supports connecting up to 4 batteries in series (4S) and 4 batteries in parallel (4P) for a maximum energy of 40.96KWh and maximum continuous load power of 40.96KW. Refer to the connection diagram for multi-battery setups.

5.3 Mounting

Mount the battery in a stable, well-ventilated area, away from direct heat or moisture. Ensure it is secured to prevent movement during operation, especially in mobile applications like RVs or marine vessels.

6. Operation

6.1 Charging

• Use a LiFePO4 compatible charger with appropriate voltage and current settings.
• The integrated BMS will protect against overcharging. However, using a charger specifically designed for LiFePO4 batteries is crucial for optimal performance and lifespan.
• Avoid charging the battery below 0°C (32°F) as the BMS will prevent it to protect the cells.

6.2 Discharging

• The battery can be discharged up to 100% Depth of Discharge (DOD) without significant damage, thanks to its robust LiFePO4 chemistry and BMS.
• The BMS will automatically cut off power if the voltage drops too low, preventing over-discharge.
• Avoid operating the battery below -20°C (-4°F).

7. Maintenance

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean as necessary.
• Cleaning: Wipe the battery casing with a dry, clean cloth. Do not use solvents or abrasive cleaners.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% state of charge and stored in a cool, dry place. Recharge every 3-6 months to prevent self-discharge.
• Temperature: While the battery has low-temperature protection, extreme temperatures (hot or cold) can affect performance and lifespan. Operate and store within recommended temperature ranges.
