The HumsiENK 12V 314Ah battery supports a 4S4P configuration, allowing for a maximum voltage of 51.2V and a maximum capacity of 1256Ah, resulting in a 64.3 kWh energy system. When connecting multiple batteries:

• Parallel Connection: Connect positive terminals together and negative terminals together to increase capacity (Ah) while maintaining voltage (V).
• Series Connection: Connect the positive terminal of one battery to the negative terminal of the next to increase voltage (V) while maintaining capacity (Ah).
• Always use cables of appropriate gauge for your current requirements.

4.3. Bluetooth App Setup

The battery features Bluetooth 5.0 technology for real-time monitoring via a mobile application. To connect:

1. Download the HumsiENK app from your device's app store.
2. Ensure Bluetooth is enabled on your mobile device.
3. Open the app and scan for available batteries.
4. Select your battery (identified by its unique ID) to connect and monitor its status.

5. Operating Instructions

5.1. Charging

Use a compatible LiFePO4 battery charger. The integrated BMS ensures safe charging by preventing overcharging and automatically cutting off charging in low temperatures (below 0°C / 32°F) to protect the battery.

The battery supports three charging modes:

• LiFePO4 Charger
• Solar Panel + MPPT (Maximum Power Point Tracking)
• Generator

5.2. Discharging

The battery can provide 4.19kWh of energy when fully charged. The 100A BMS protects against over-discharging and over-current conditions. The discharge temperature range is -20°C to 70°C (-4°F to 158°F).

5.3. Applications

This battery is suitable for a wide range of applications, including:

• Home energy storage
• UPS backup power
• RV and camper power systems
• Golf carts
• Trolling motors and yachts
• Solar systems and off-grid applications
• Digital/CCTV cameras and DIY projects

6. Maintenance

• Keep the battery terminals clean and free from corrosion.
• Store the battery in a cool, dry place away from direct sunlight and extreme temperatures.
• For long-term storage, charge the battery to approximately 50% State of Charge (SOC) and check its voltage periodically.
• Avoid fully discharging the battery for extended periods.
• Regularly inspect the battery for any signs of damage or swelling.

7. Troubleshooting

The integrated BMS provides various protections. If the battery is not functioning as expected, check the following:

• No Power Output: Check terminal connections for tightness and corrosion. Verify the battery's State of Charge (SOC) via the Bluetooth app. The BMS might have triggered a protection (e.g., over-discharge, over-current).
• Not Charging: Ensure the charger is compatible and properly connected. Check the charging temperature; the BMS will prevent charging below 0°C (32°F). Verify the charger's output voltage and current.
• Bluetooth Connectivity Issues: Ensure your device is within 15 meters of the battery. Restart the app and your device.
• Unusual Heat: Disconnect the battery immediately and contact support.

For persistent issues, refer to the detailed specifications and contact HumsiENK customer support.
