3. Setup and Connection
3.1. Battery Series/Parallel Connection Methods
To ensure optimal performance and safety when connecting multiple batteries in series or parallel, it is crucial that the total path of current in and out of each battery is equal. There are four recommended methods:
- Diagonal Connection: Ensures balanced current flow.
- Equal Length Cables: The length of the cable from the inverter to each battery must be equal.
- Center Diagonal Connection: Ensures all cables are of the same length.
- Busbar Connection: Utilizes bus bars for efficient and balanced connections.
Important Note:
Before connecting batteries in series or parallel, fully charge each individual battery. The capacity of each battery should remain fully charged, and the voltage difference between them should be within 0.5V. After charging, connect them in parallel for 24 hours to allow for automatic balancing.

5. Maintenance and Precautions
Adhering to these precautions will help ensure the longevity and safe operation of your battery:
- Never immerse the battery in water.
- Do not expose the battery pack to fire or excessive heat.
- Do not charge or use the battery outside the specified temperature range (Charge: 0~60°C, Discharge: -20~60°C). Avoid storing, charging, or using the product near fire and heat sources.
- If the battery pack emits odor or leaks, immediately stop using and charging it. Move it to an open and ventilated area, away from any fire sources, and contact support promptly.
- When connecting to a load, ensure correct polarity; do not reverse the positive and negative terminals.
- Avoid short-circuiting the positive and negative electrodes of the battery with metal conductors.
- The optimal operating temperature for the product is 25±5°C. If used outside this range, the discharge capacity may be reduced.
6. Troubleshooting
Your Anern LiFePO4 battery is equipped with an advanced Battery Management System (BMS) that provides multiple layers of protection. If you experience any issues, consider the following:
- Automatic Protections: The BMS automatically protects against overvoltage, undervoltage, overcurrent (charge/discharge), short circuits, and over/undertemperature conditions. If the battery stops functioning, it might be due to one of these protections being triggered. Allow the battery to return to normal operating conditions or resolve the triggering factor.
- General Malfunction: In case of any failure or abnormality during use, please contact Anern customer support. Do not attempt to open or remove the battery pack without authorization, as this may void your warranty and pose safety risks.
7. User Tips
- When connecting multiple batteries, ensure that the bolts used are appropriate for the cell configuration (e.g., for a 6-cell battery).
- Always verify the voltage and capacity of individual batteries before combining them in series or parallel to ensure compatibility and balanced operation.
8. Warranty and Support
For any product-related inquiries, technical assistance, or in the event of a malfunction, please contact Anern customer support. Unauthorized disassembly or modification of the battery pack is not recommended and may void your warranty.
