2. Key Features and Benefits

• Advanced Battery Management System (BMS): The integrated BMS acts as the 'brain' of the battery, providing crucial protections against short circuits, overcharging, and reverse polarity. It also includes temperature monitoring to ensure safe operation.
• Thermal Core Heating Technology (Heated Version): For the heated version of this battery, Thermal Core technology automatically warms the battery cells when charging at temperatures below freezing. This ensures a safe and efficient charge once the optimal temperature is reached, preserving battery life, especially in colder climates.
• Bluetooth Connectivity & Norsk Guardian App: Connect your smartphone to the battery via Bluetooth using the free Norsk Guardian App. This app allows you to monitor multiple batteries simultaneously, create custom battery groups, check charge status and current draw, set up alert notifications, and activate advanced features like Deep Sleep.
• One-Touch Power Management Button: Located on the top of the battery, this button, along with bright LEDs, allows for quick checks of battery status and activation of advanced features such as resetting the BMS or enabling Deep Sleep.
• Deep Sleep Advanced Storage: This feature allows you to easily disconnect power from the battery's terminals, either through the Norsk Guardian App or the one-touch button. This eliminates phantom drain and prevents fully discharged batteries, making it perfect for seasonal or long-term storage.
• IP67 Waterproof Rating: The battery boasts an IP67 rating, ensuring complete protection against dust and water immersion up to 1 meter for 30 minutes, making it highly suitable for marine applications.
• Extended Lifespan: Rated for over 4,000 charge cycles, this battery offers an estimated lifespan of 15-20 years of dependable performance. A charge cycle is defined as completely draining and then fully recharging the battery.

3. Setup

1. Initial Charging: Before first use, ensure the battery is fully charged using a compatible LiFePO4 charger. Refer to your charger's manual for specific instructions.
2. Physical Installation: Install the battery in a secure, well-ventilated location. Connect your devices to the M8 posts and bolts terminals, ensuring correct polarity (red for positive, black for negative).
3. Norsk Guardian App Connection: Download the free Norsk Guardian App from your device's app store. Enable Bluetooth on your smartphone and open the app. Follow the in-app instructions to connect to your Norsk Lithium battery. You can monitor multiple batteries and create custom groups for easier management.

4. Operating the Battery

• Powering Devices: Once connected, the battery will provide stable 12V power to your marine electronics, trolling motors, or other accessories.
• Checking Battery Status:
  • Via Norsk Guardian App: Open the app to view real-time charge status, voltage, current draw, temperature, and remaining capacity.
  • Via One-Touch Power Management Button: A quick press of the button on top of the battery will illuminate the LED indicators, showing the current state of charge.
• Series/Parallel Connections: This 12V 120AH battery can be combined in series for 24V or 36V trolling motor applications. Consult a qualified technician or the Norsk Lithium support for proper wiring configurations to ensure safety and optimal performance.
• Activating Deep Sleep: For long-term storage, activate Deep Sleep mode via the Norsk Guardian App or by a long press on the power management button (refer to the button's instructions on the battery label for specific light patterns). This will disconnect the battery's terminals internally, preventing self-discharge.

5. Maintenance

• Regular Charging: For optimal lifespan, avoid prolonged storage in a fully discharged state. Recharge the battery after each significant use.
• Cold Weather Charging: If you have the heated version, the Thermal Core technology will manage charging in sub-freezing temperatures. For non-heated versions, avoid charging below 0°C (32°F) to prevent damage.
• Long-Term Storage: For storage periods exceeding one month, activate Deep Sleep mode. Store the battery in a cool, dry place away from direct sunlight and extreme temperatures.
• Cleaning: Keep the battery terminals clean and free of corrosion. Use a dry cloth to wipe down the battery case. Do not use harsh chemicals or abrasive cleaners.

6. Troubleshooting

If you encounter issues with your Norsk Lithium battery, consider the following common solutions:

• Battery Not Powering On: Ensure the battery is not in Deep Sleep mode. If it is, activate it via the app or the power management button. Check all cable connections for tightness and correct polarity.
• Charging Issues: Verify that your charger is compatible with LiFePO4 batteries and is functioning correctly. Ensure the battery temperature is within the safe charging range (above 0°C for non-heated, managed by Thermal Core for heated).
• App Connectivity Problems: Ensure Bluetooth is enabled on your phone and the battery is within range. Try restarting the app or your phone.
• Resetting the BMS: If the battery is unresponsive, you can reset the BMS by a specific sequence using the one-touch power management button (refer to the battery label for details) or through the Norsk Guardian App.

For persistent issues, refer to the detailed troubleshooting guide within the Norsk Guardian App or contact Norsk Lithium customer support.
