3. Setup

Unboxing and Initial Inspection

Upon receiving your Power Queen battery and charger, carefully inspect the packaging for any signs of damage. Remove all components and verify that all items listed in the 'What's in the Box' section are present. If any items are missing or damaged, contact customer support immediately.

Connecting the Battery and Charger

The included 12V 20A LiFePO4 battery charger is designed for safe and efficient charging. Follow these steps to connect and charge your battery:

1. Ensure the charger is unplugged from the wall outlet.
2. Connect the red (+) clamp of the charger to the positive (+) terminal of the battery.
3. Connect the black (-) clamp of the charger to the negative (-) terminal of the battery.
4. Plug the charger into a standard wall outlet. The charger's indicator light will show the charging status (e.g., red for charging, green for fully charged).
5. Once fully charged, unplug the charger from the wall outlet first, then disconnect the clamps from the battery terminals.

Terminal Connections

The battery features M8 terminals. Ensure all connections are secure and properly tightened to prevent arcing and ensure efficient power transfer. Use the provided insulating caps for safety.

4. Operating Instructions

Series and Parallel Connections

The Power Queen 12V 100Ah battery supports both series and parallel connections to achieve higher voltage or capacity:

• Parallel Connection: Connect batteries in parallel to increase total capacity (Ah) while maintaining the same voltage (12V). Up to 16 batteries can be connected in parallel.
• Series Connection: Connect batteries in series to increase total voltage (V) while maintaining the same capacity (100Ah). Up to 4 batteries can be connected in series to achieve 48V.
• Series-Parallel Combination: For maximum energy output, up to 16 batteries can be configured in a 4P4S (4 parallel, 4 series) setup, reaching 51.2V 400Ah (20.48kWh).

Always use appropriate cables and ensure all batteries are at a similar state of charge before making series or parallel connections.

Battery Management System (BMS)

The integrated 100A BMS actively monitors and protects the battery from various conditions, ensuring safe and reliable operation. This includes protection against:

• Overcharge
• Over-discharge
• Over-current
• Over-voltage
• Overload
• Short circuit

5. Maintenance

Charging Recommendations

For optimal battery health and longevity, it is recommended to charge the battery at 14.6V charging voltage and 20A charging current. This typically takes approximately 5 hours to fully charge a depleted 100Ah battery.

Storage

When storing the battery for extended periods, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place away from direct sunlight and extreme temperatures. The BMS will protect the battery during storage.

6. Troubleshooting

Common Issues and Solutions

• Battery Not Charging: Check all cable connections for tightness and correct polarity. Ensure the charger is plugged into a working outlet and its indicator light is active. If the battery is too cold, the BMS's low-temperature protection may prevent charging until the temperature rises.
• No Power Output: Verify that the battery is sufficiently charged. Check all connections to your load for tightness. The BMS may have activated a protection mode (e.g., over-discharge, over-current) if the battery was subjected to extreme conditions. Disconnect the load and allow the battery to rest, or apply a small charge to reset the BMS.
• Charger Indicator Light Flashing Red: This indicates a fault. Disconnect the charger from the battery and the wall, then reconnect. If the issue persists, consult the charger's manual or contact customer support.
