Setup and Installation

Proper setup is crucial for the performance and safety of your battery. Follow these guidelines:

1. Pre-Installation Check:

• Inspect the battery for any physical damage.
• Ensure all connections are clean and free of corrosion.
• Verify that your charging system is compatible with LiFePO4 batteries.

2. Connecting the Battery:

• Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/charger.
• Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/charger.
• Use appropriate gauge cables for your application to prevent overheating.
• Ensure all connections are tight and secure.

3. Series and Parallel Connections:

The battery supports both series and parallel connections to achieve higher voltage or capacity:

• Parallel Connection: Connect up to 4 batteries in parallel to increase total capacity (e.g., 4 x 200Ah = 800Ah at 12V). Ensure all batteries are at a similar state of charge before connecting in parallel.
• Series Connection: Connect up to 4 batteries in series to increase total voltage (e.g., 2 batteries for 24V, 3 for 36V, 4 for 48V). Ensure all batteries are of the same model and capacity when connecting in series.

Warning: Incorrect series or parallel connections can damage the battery and connected equipment. Consult a professional if unsure.

Operating Instructions

1. Charging:

Use a LiFePO4 compatible charger. The recommended charging voltage is typically between 14.2V and 14.6V. Avoid overcharging or undercharging, as the integrated BMS will protect the battery.

2. Discharging:

The battery is designed for deep-cycle applications. The BMS will automatically cut off discharge if the voltage drops too low or if the current exceeds safe limits. Ensure your load does not exceed the battery's continuous discharge current rating (200A, as per BMS). The battery can support significant loads, as demonstrated by its 2560Wh energy capacity.

This image shows the battery connected to an inverter, powering common household appliances like a coffee maker (800W for 3.2H), refrigerator (200W for 12.8H), heater (1500W for 1.7H), and light (20W for 128H), demonstrating its 2560Wh energy capacity.

Maintenance

• Regular Inspection: Periodically check the battery terminals for cleanliness and tightness.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% capacity. Store in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cleaning: Use a dry cloth to clean the battery casing. Do not use solvents or abrasive cleaners.
• Temperature: Avoid operating or storing the battery outside its recommended temperature range to maximize lifespan.

Troubleshooting

• Battery Not Charging:
  • Check charger compatibility and connections.
  • Verify input power to the charger.
  • Ensure battery temperature is above 0°C (32°F) for charging.
• Battery Not Discharging/No Power Output:
  • Check load connections and ensure they are secure.
  • Verify that the load does not exceed the battery's maximum discharge current.
  • Ensure battery temperature is above -20°C (-4°F) for discharging.
  • The BMS may have activated a protection mode (e.g., low voltage, overcurrent). Disconnect the load and allow the battery to rest or charge.
• Reduced Capacity/Short Runtime:
  • Ensure the battery is fully charged.
  • Check for excessive load or parasitic drains.
  • Verify battery age and cycle count. While designed for long life, capacity can gradually decrease over many years of heavy use.
