4. Setup and Installation

Before installation, ensure all components are present and undamaged. The package includes one 12V100AH LiFePO4 battery.

4.1. Pre-Installation Checklist

• Verify battery voltage and capacity match your system requirements.
• Ensure all cables and connectors are appropriately sized for the expected current.
• Confirm the charging source is compatible with LiFePO4 batteries.
• Prepare a clean, dry, and well-ventilated installation area.

4.2. Connecting the Battery

The battery terminals are M8 bolts. Ensure secure connections to prevent arcing and power loss.

1. Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/system.
2. Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/system.
3. For multiple batteries in series or parallel, refer to section 4.3.
4. Ensure all connections are tight and secure.

4.3. Series and Parallel Connections

This battery supports up to 4S4P configurations for increased voltage or capacity:

• Series Connection (4S): Connect up to four batteries in series to achieve a maximum voltage of 48V (51.2V nominal). This increases the system voltage while maintaining the same capacity (e.g., 48V 100Ah).
• Parallel Connection (4P): Connect up to four batteries in parallel to achieve a maximum capacity of 400Ah while maintaining 12V. This increases the total energy storage (e.g., 12V 400Ah).
• Series-Parallel Connection (4S4P): Combine series and parallel connections for a maximum system of 48V 400Ah (20.48kWh).

Important: When connecting multiple batteries, ensure all batteries are at a similar state of charge before connecting them. Use appropriate busbars and cables for high current applications.

6. Maintenance

LiFePO4 batteries require minimal maintenance compared to lead-acid batteries. Follow these guidelines to ensure optimal performance and longevity:

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals if necessary.
• Keep Clean and Dry: Ensure the battery surface is clean and dry. Avoid dust and moisture accumulation.
• Temperature Management: While the battery operates across a wide temperature range, prolonged exposure to extreme temperatures (especially above 150°F or below -4°F) can affect performance and lifespan. Store in a cool, dry place when not in use.
• Storage: If storing the battery for an extended period, charge it to approximately 50% State of Charge (SOC) and disconnect it from any loads or chargers. Recharge every 3-6 months to prevent deep discharge.
• Avoid Deep Discharge: The built-in BMS protects against over-discharge, but it's good practice to avoid consistently running the battery to its lowest voltage limit.
