3. Enstalasyon ak Enstalasyon
3.1 Debake
Retire batri a nan anbalaj li avèk prekosyon. Enspekte pou wè si gen nenpòt domaj vizib. Si ou jwenn domaj, kontakte sèvis kliyan imedyatman.
3.2 Premye chaj
It is recommended to fully charge the battery before its first use to ensure optimal performance and calibration of the BMS.
3.3 Connecting Batteries (Series/Parallel)
This battery can be connected in series or parallel to achieve higher voltage or capacity. For example, up to 4 units can be connected in a 1S4P (1 series, 4 parallel) configuration to achieve 51.2V 400Ah (20.48kWh) capacity, suitable for 48V solar inverters and whole-home backup systems.
- When connecting in series or parallel, all batteries must be identical (same brand, type, voltage, capacity, and BMS) and purchased within 1 month of each other to ensure compatibility and balanced operation.
- Always use appropriate cables and connectors rated for the expected current.
- Asire w ke tout koneksyon an sekirite epi byen izole.
3.4 Dimansyon fizik ak tèminal yo
The battery dimensions are approximately L20.47 x W10.59 x H8.66 inches (L52.0 x W26.9 x H22.0 cm). It weighs approximately 68.78 lbs (31.2 kg). The battery is equipped with M8 terminals.
4. Operasyon Enstriksyon

- Discharging stops at -4°F (-20°C) and below.
5. Antretyen
Proper maintenance ensures the longevity and optimal performance of your Dumfume LiFePO4 battery.
- Chaj regilye: If the battery is not in regular use, charge and discharge it once every 6 months to prevent damage from disuse.
- Depo: For long-term storage, ensure the battery is charged to 30-50% of its capacity. Store in a cool, dry, and well-ventilated area, away from direct sunlight and extreme temperatures.
- Netwayaj: Keep the battery terminals clean and free from corrosion. Use a dry cloth to wipe down the battery casing.
- Enspeksyon: Periodically inspect the battery for any signs of physical damage or loose connections.
NAN. Depanaj
If you encounter issues with your Dumfume LiFePO4 battery, refer to the following common troubleshooting points:
- Batri a pa chaje/pa dechaje: The built-in BMS may have activated a protection mode due to overcharge, over-discharge, overcurrent, short circuit, or extreme temperature. Allow the battery to return to normal operating conditions or address the fault condition.
- Voltage/Current Deviations: Due to variations in temperature, humidity, measurement methods, and instruments, voltage and current readings may deviate by 1% to 5%. This is considered normal.
- Pèfòmans redwi: Ensure the battery is adequately charged and that all connections are secure. Verify that the load is within the battery's specifications.
If problems persist or you have safety concerns, please feel free to contact Dumfume customer support for assistance.
