5. Setup and Installation
5.1. Terminal Connections
Ensure all connections are secure. If using OT terminals directly with screws and the terminal thickness is less than 2mm, add gaskets for lock attachment to prevent loosening and overheating.
5.2. Series and Parallel Connections
The Litime 24V 100Ah battery supports various configurations to meet your power needs:
- Parallel Connection: Support connecting up to 4 identical batteries for up to a 24V (25.6V) 400Ah battery system. This increases the total amperage capacity while maintaining the voltage.
- Series Connection: Support connecting up to 2 identical batteries for up to a 48V (51.2V) 100Ah battery system. This increases the total voltage while maintaining the amperage capacity.
- Series-Parallel Connection: For larger systems, up to 8 identical batteries can be connected in a 4P2S configuration to achieve a 48V (51.2V) 400Ah system with 20.48kWh of energy.
Important: When connecting batteries in series or parallel, all batteries must be of the same brand, type, voltage, capacity, and have been purchased within 1 month to ensure compatibility and optimal performance.

8. Troubleshooting
The Litime 24V 100Ah LiFePO4 battery is equipped with a robust 100A Battery Management System (BMS) to protect against common issues and ensure safe operation.
BMS Protection Functions:
- Overcharge Protection
- Over-Discharge Protection
- Over-Current Protection
- Short Circuit Protection
- Overheating Protection
- Low Temperature Cut-Off (for specific models, check product details)
If the battery enters a protection state (e.g., no output), it may be due to one of the above conditions. Allow the battery to return to normal operating parameters or use a compatible LiFePO4 charger with an activation function if the voltage is below 10V.
