2. Safety Instructions
Adherence to these safety guidelines is crucial for safe operation and to prevent damage to the battery or injury.
- Do not use this battery as a starting battery for vehicles, golf cart batteries, or for operating jacks. It is intended for energy storage purposes only.
- Ensure proper ventilation when operating the battery, especially in enclosed spaces.
- Avoid exposing the battery to fire, direct sunlight, or temperatures outside the specified operating range.
- Do not disassemble, puncture, or modify the battery. This can lead to dangerous situations.
- Use only compatible chargers designed for LiFePO4 batteries.
- Keep the battery away from water and moisture.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- In case of fire, use a Class D fire extinguisher. Water or foam may not be effective.

3. Setup and Installation
Unpacking
Carefully remove the battery from its packaging. Inspect the battery for any signs of damage during transit. If damage is observed, contact customer support immediately.
Connection Guidelines
The Dumfume 12V 100Ah Mini LiFePO4 battery supports both parallel and series connections. This allows for increased capacity or voltage to meet specific power requirements.
- Parallel Connection: Connect batteries in parallel to increase total capacity while maintaining the same voltage. Ensure all batteries have similar voltage levels before connecting.
- Series Connection: Connect batteries in series to increase total voltage. This model supports up to 4S (four batteries in series) and 4P (four parallel strings), allowing for a maximum system capacity of 20.48kWh.
- Always use appropriate cables and connectors rated for the expected current.
- Ensure correct polarity when making connections (positive to positive, negative to negative for parallel; positive of one to negative of next for series).
Physical Dimensions
The compact design of the battery facilitates installation in various setups.

4. Operation
Charging
Use a LiFePO4 compatible charger. Ensure the charger's voltage and current settings are appropriate for a 12V LiFePO4 battery. Overcharging or using an incompatible charger can damage the battery and void the warranty.
Discharging
The battery is designed for deep cycle applications. The integrated BMS protects against over-discharge. Avoid drawing current beyond the battery's rated maximum discharge current.
Operating Temperature Range
The battery offers excellent discharge performance across a wide temperature range. The BMS provides protection for temperature extremes.
- Discharging Temperature: -4°F to 158°F (-20°C to 70°C)
- Charging Temperature: Consult the specific charger's manual and battery specifications for optimal charging temperature ranges. The BMS will cut off charging if temperatures are too low or too high.

5. Maintenance
Storage
For optimal battery health during prolonged storage, it is recommended to charge and discharge the battery once every six months. Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
Cleaning
Keep the battery terminals clean and free from corrosion. Use a dry cloth to wipe down the battery casing. Do not use harsh chemicals or abrasive materials.
6. Troubleshooting
Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incompatible charger, loose connections, BMS protection engaged (e.g., low temperature) | Verify charger compatibility, check all cable connections, ensure ambient temperature is within charging range. |
| Battery not discharging | Over-discharge protection engaged, loose connections, load exceeding maximum current | Check connections, reduce load, allow battery to rest or attempt a small charge to reset BMS. |
| Reduced capacity/runtime | Aging, improper charging/discharging habits, extreme operating conditions | Review usage patterns, ensure proper charging, consider battery age. |
