Setup

Initial Charging

Before first use, ensure the battery is fully charged using a compatible LiFePO4 battery charger. The maximum charge current is 6A. Solar panels with MPPT controllers or generators can also be used for recharging.

Connecting Multiple Batteries (Series/Parallel)

The GOLDENMATE 12V 12Ah LiFePO4 battery supports flexible expansion for increased voltage or capacity. You can connect up to 8 batteries in series or parallel configurations.

• Parallel Connection: Connect batteries in parallel to increase total capacity while maintaining the same voltage (e.g., 12V 24Ah with two batteries).
• Series Connection: Connect batteries in series to increase total voltage (e.g., 25.6V 12Ah with two batteries).

Ensure all batteries are at a similar state of charge before connecting them in series or parallel. Use appropriate cables and connectors rated for the expected current and voltage.

Troubleshooting

The built-in Battery Management System (BMS) is designed to protect the battery from various issues. If you experience problems, consider the following:

• No Power Output: Check if the battery is fully charged. Ensure all connections are secure and free from corrosion. The BMS might have activated a protection mode (e.g., over-discharge protection); try connecting to a charger to reset.
• Slow Charging: Verify that your charger is compatible with LiFePO4 batteries and provides the correct voltage (14.4V max) and current. Ensure the charging environment temperature is within the recommended range (0°C to 45°C).
• Battery Not Holding Charge: This could indicate a fault with the battery or charger. Ensure the charger is functioning correctly. If the issue persists, contact customer support.
• Overheating: The BMS includes overheating protection. If the battery feels excessively hot, disconnect it immediately and allow it to cool down. Ensure proper ventilation around the battery during operation and charging.

For persistent issues not resolved by these steps, please refer to the Warranty & Support section for assistance.
