6. Operating Instructions

Your Wattcycle battery is designed for ease of use with smart monitoring capabilities:

• Initial Charge: For optimal performance, fully charge the battery before its first use.
• Bluetooth App: Download the WattCycle app from your device's app store. Connect to your battery via Bluetooth to monitor its status in real-time. The app provides data on voltage, current, temperature, and state of charge.
• Charging: The battery supports various charging methods including LiFePO4 chargers, solar panels (with appropriate controller), and alternators. Ensure your charging source is compatible with LiFePO4 batteries.
• Discharging: The battery is suitable for powering a wide range of applications such as RVs, marine equipment, and general power backup. The integrated BMS protects against over-discharge.

7. Maintenance and Storage

Proper maintenance ensures the longevity and performance of your battery:

• Regular Inspection: Periodically check battery terminals for corrosion and ensure connections are tight.
• Cleaning: Keep the battery clean and dry. Use a soft, dry cloth to wipe down the battery casing.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place. The BMS will protect against low-temperature damage.
• Temperature Considerations: Avoid operating or storing the battery in extreme temperatures outside the specified range (-4°F to 158°F). The battery's low-temperature cut-off feature will prevent charging below 32°F.

8. Troubleshooting

The Smart BMS provides comprehensive protection. If you experience issues, check the following:

• No Power Output: Check battery connections for tightness and correct polarity. Verify the battery's state of charge via the app. The BMS may have activated a protection mode (e.g., over-discharge, low temperature).
• Charging Issues: Ensure your charger is compatible with LiFePO4 batteries and operating correctly. Check for low-temperature cut-off if charging in cold conditions.
• App Connectivity: Ensure Bluetooth is enabled on your device and the battery is within range. Restart the app or battery if connection issues persist.
• BMS Fault: If the battery enters a fault state, the BMS will typically shut down to protect the cells. Refer to the app for specific fault codes or contact support.
