5. Setup

5.1 Initial Inspection

Upon receiving your battery, inspect it for any visible damage. If damage is found, do not attempt to use the battery and contact customer support immediately.

5.2 Initial Charge

It is recommended to fully charge the battery before its first use. Use a compatible LiFePO4 charger with a charge voltage between 14.2V and 14.6V and a charge current between 5A and 50A.

5.3 Connecting the Battery

The VEMDIA LiFePO4 battery is designed for versatility and can be connected in series or parallel to meet your system's voltage and capacity requirements. Always ensure all batteries are at a similar state of charge before connecting them in parallel.

• Parallel Connection: Connect positive terminals together and negative terminals together to increase total capacity (Ah) while maintaining the same voltage (12.8V).
• Series Connection: Connect the positive terminal of one battery to the negative terminal of the next to increase the total voltage. For example, two batteries in series will provide 25.6V, and four batteries in series will provide 51.2V.

Figure 3: The battery supports series connections for higher voltage systems (e.g., X1 for 12.8V, X2 for 25.6V, X4 for 51.2V).

IMPORTANT: When connecting batteries in series or parallel, ensure all connections are secure and use appropriate gauge cables to prevent overheating and ensure efficient power transfer. Consult a qualified electrician if you are unsure about wiring configurations.

5.4 Connecting to Appliances/Inverters

The battery can be connected to inverters and other electrical appliances. Ensure that the inverter's input voltage range matches the battery's output voltage and that the total load power does not exceed the battery's maximum load power of 1280W or maximum discharge current of 100A.

7. Maintenance

LiFePO4 batteries are generally low-maintenance, but following these guidelines will ensure optimal performance and longevity:

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary and ensure they are tightened securely.
• Keep Clean and Dry: Ensure the battery surface is clean and dry. Avoid dust, dirt, and moisture accumulation.
• Temperature Control: Operate and store the battery within recommended temperature ranges. While LiFePO4 batteries perform well at high and low temperatures, extreme conditions can affect performance and lifespan.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% of its capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures. Recharge every 3-6 months to prevent deep discharge.
• Avoid Deep Discharge: While designed for deep cycles, consistently discharging the battery to 0% can reduce its overall lifespan. It's best practice to recharge before it's completely depleted.

  • Inspect cables and terminals: Look for loose or corroded connections.
  • Check battery temperature: If the battery is too hot or too cold, it may not charge. Allow it to return to a moderate temperature.
• Battery Not Discharging/Low Power Output:
  • Check load connections: Ensure all appliances are correctly connected to the battery.
  • Verify load power: Confirm that the total power draw of your appliances does not exceed the battery's maximum load power (1280W) or discharge current (100A).
  • Check battery charge level: The battery may be depleted. Attempt to recharge it.
  • Inspect cables and terminals: Ensure all connections are secure and free of corrosion.
• Unusual Odor or Heat:
