5. 설정
Proper setup is crucial for the performance and longevity of your LiFePO4 battery. Please follow these guidelines carefully.
5.1 초기 검사
Before installation, inspect each battery for any visible damage. Ensure the terminals are clean and free from debris.
5.2 직렬 및 병렬 연결
Your Dumfume LiFePO4 batteries can be connected in series or parallel to achieve higher voltage or capacity, respectively. The maximum configuration supported is 2S4P (2 batteries in series, 4 parallel strings).
- Important Rule for Series/Parallel Connections: To connect batteries in series or parallel, all batteries must be identical (same brand, type, voltage, capacity, and BMS) and ideally purchased within the same month to ensure optimal balance and performance.
- 직렬 연결: Connect the positive terminal of one battery to the negative terminal of the next to increase the total voltage. 예를 들어ample, connecting two 25.6V batteries in series will result in a 51.2V system.
- 병렬 연결: Connect positive terminals together and negative terminals together to increase the total capacity while maintaining the same voltage. 예를 들어ample, connecting two 25.6V 100Ah batteries in parallel will result in a 25.6V 200Ah system.
5.3 터미널 연결
Use the provided M8 terminal bolts to connect your battery to your system. Ensure connections are tight and secure to prevent resistance and overheating. Use the insulating caps to cover the terminals after connection to prevent accidental short circuits.
5.4 초기 충전
It is recommended to fully charge the battery before its first use to ensure optimal performance and calibration of the BMS.

8. 문제 해결
The integrated BMS provides protection against common issues. If the battery stops functioning, it may be due to a BMS protection trigger. Follow these general troubleshooting steps:
- 전원 출력 없음:
- Check all connections for tightness and proper polarity.
- Verify that the load is not exceeding the maximum continuous discharge current (100A) or power (2560W).
- The BMS may have triggered due to over-discharge. Attempt to charge the battery with a compatible LiFePO4 charger.
- 배터리가 충전되지 않음:
- Ensure the charger is compatible with LiFePO4 batteries and set to the correct voltag전자(29.2V).
- Check charging current is within the recommended range (20-50A).
- Verify that the ambient temperature is within the charging temperature range (32°F to 149°F / 0°C to 65°C).
- The BMS may have triggered due to overcharge or high temperature. Disconnect the charger and allow the battery to cool down.
- 평소와 다른 냄새 또는 부기:
- 배터리를 모든 부하 및 충전기에서 즉시 분리하십시오.
- Move the battery to a safe, well-ventilated area away from flammable materials.
- Do not attempt to use or repair the battery. Contact support immediately.
- 단락 보호:
- If a short circuit occurs, the BMS will cut off power. Remove the short circuit and the battery should automatically reset or require a brief charge to reactivate.
If issues persist after following these steps, please contact Dumfume customer support for assistance.
9. 사용자 팁
- 시스템 크기: Always ensure your battery capacity and power output are appropriately sized for your application's energy demands to prevent frequent over-discharge or over-current events.
- 케이블 크기: Use appropriately gauged cables for your connections to minimize voltage drop and prevent overheating, especially for high-current applications.
