5. Setup
5.1 Unpacking and Inspection
Carefully unpack the battery and inspect it for any signs of damage. Report any damage to the supplier immediately.
5.2 Mounting
Mount the battery in a clean, dry, and well-ventilated area. Ensure the mounting surface is sturdy enough to support the battery's weight. Maintain adequate clearance around the battery for air circulation and access to terminals.
5.3 Electrical Connections
Connect the battery using appropriate M8 terminals and cables. Ensure all connections are tight and secure to prevent arcing and overheating. Observe correct polarity: positive to positive, negative to negative.
Series and Parallel Connection:
The NewtiPower 48V 100Ah LiFePO4 Battery supports both parallel and series connections to achieve desired voltage and capacity. When connecting in series, ensure the total system voltage does not exceed 80V. For parallel connections, ensure all batteries are of the same voltage and capacity to prevent imbalances.

6. Operating Instructions
6.1 Charging
Use a compatible LiFePO4 charger with the correct voltage and current settings. The battery can be charged using various methods:
- Dedicated AC charger.
- Solar panels with a compatible charge controller.
- Generator with a DC-DC charger.
Ensure charging parameters are within the battery's specifications to prevent damage and ensure longevity.
6.2 Discharging
The battery supports 100% depth of discharge. However, for optimal lifespan, avoid consistently discharging to 0% state of charge. The BMS will protect the battery from over-discharge.
6.3 Monitoring
The battery can be monitored via a dedicated application on your smartphone or tablet, connecting via WiFi. This allows you to view real-time information such as voltage, current, temperature, and state of charge.

7. Maintenance
- Regular Inspection: Periodically check battery terminals for corrosion or loose connections. Clean terminals if necessary.
- Cleaning: Keep the battery surface clean and dry. Use a soft, damp cloth for cleaning; avoid harsh chemicals.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% state of charge and stored in a cool, dry place away from direct sunlight and extreme temperatures.
- Ventilation: Ensure the battery area remains well-ventilated to prevent heat buildup.
8. Troubleshooting
8.1 Battery Not Charging
- Check all cable connections for tightness and correct polarity.
- Verify that the charger is compatible with LiFePO4 batteries and is functioning correctly.
- Ensure the charging voltage and current settings are appropriate for a 48V LiFePO4 battery.
- If the battery has been deeply discharged, the BMS might have activated protection. Try connecting to a charger for a few minutes to reset the BMS.
8.2 Low Power Output
- Check the battery's state of charge via the monitoring app or display.
- Inspect connections for any loose or corroded points that could increase resistance.
- Ensure the load is not exceeding the battery's continuous discharge current rating (100A).
8.3 BMS Protection Activated
If the battery suddenly stops functioning, the BMS may have activated a protection mode (e.g., over-voltage, under-voltage, over-current, over-temperature). Disconnect the load/charger, allow the battery to rest, and address the underlying cause. The BMS typically resets automatically once the fault condition is removed.
9. Warranty
The NewtiPower 48V 100Ah LiFePO4 Battery comes with a 10-year manufacturer warranty. This warranty covers defects in materials and workmanship under normal use and service. Please retain your proof of purchase for warranty claims. The warranty does not cover damage caused by misuse, abuse, improper installation, or unauthorized modifications.
