4. What's in the Box
Upon unpacking, verify that all items are present and undamaged:
- 1 x Power Queen 12.8V 100Ah Group 31 LiFePO4 Battery
- M8 - 35/64" (14MM) Terminal Bolts
- 2 x Insulating Caps for Bolts
- Product Instruction Manual (this document)
5. Setup
5.1 Initial Inspection
Before connecting, inspect the battery for any visible damage. Ensure terminals are clean and free of debris.
5.2 Terminal Connection
Connect the battery to your system using the provided M8 terminal bolts. Ensure connections are secure to prevent loosening or overheating. If using OT terminals directly with screws less than 2mm thick, add gaskets to ensure secure attachment.

5.3 Charging Instructions
For optimal performance and lifespan, charge the battery using a dedicated 14.6V 20A LiFePO4 battery charger. A full charge typically takes approximately 5 hours. Avoid using chargers designed for lead-acid batteries.
6. Operating Instructions
6.1 Series and Parallel Connections
The Power Queen 12.8V 100Ah battery can be connected in series or parallel to achieve higher voltage or capacity:
- Parallel Connection (4P): Connect up to four batteries in parallel to achieve a maximum capacity of 400Ah at 12.8V. This increases the total available energy while maintaining the nominal voltage.
- 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 nominal capacity of a single battery.
- Series and Parallel (4P4S): For advanced systems, batteries can be configured in both series and parallel to achieve higher voltage and capacity, up to 48V and 400Ah (20.48 kWh).
Always ensure all batteries in a series or parallel bank are of the same type, capacity, and state of charge before connecting. Consult a qualified electrician for complex configurations.

7. Maintenance
LiFePO4 batteries require minimal maintenance compared to lead-acid batteries. Follow these guidelines for optimal performance:
- Regular Inspection: Periodically check battery terminals for corrosion or loose connections. Clean as necessary.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SoC) and stored in a cool, dry place.
- Charging: Always use a compatible LiFePO4 charger. Avoid overcharging or undercharging. The built-in BMS will manage these aspects, but using the correct charger is crucial.
- Temperature: Operate the battery within its specified temperature range. Avoid extreme hot or cold conditions.
8. Troubleshooting
The integrated 100A BMS (Battery Management System) is designed to protect the battery from common issues. If you experience problems, consider the following:
- No Power Output: Check all connections for tightness and proper polarity. Ensure the battery is adequately charged. The BMS may have activated a protection mode (e.g., over-discharge).
- Charging Issues: Verify that the charger is specifically designed for LiFePO4 batteries and that its voltage and current settings are correct (e.g., 14.6V 20A). Check the charger's indicator lights for error codes.
- Overheating: Ensure proper ventilation around the battery. If terminals or cables are hot, check for loose connections or undersized wiring. If OT terminals are attached directly with screws and their thickness is less than 2mm, add gaskets to ensure secure attachment and prevent loosening or overheating.
- BMS Protection Activation: The BMS protects against overcharge, over-discharge, over-current, and short circuits. If the battery stops functioning, it might be due to one of these protections. Disconnect the load/charger, wait a few minutes, and then attempt to reconnect or charge.
If issues persist, contact Power Queen customer service for assistance.
