Once installed, open the app and follow the on-screen instructions to pair with your Redodo battery via Bluetooth 5.0. The app allows you to monitor various parameters and remotely control discharge/cutoff functions within a 10-meter range.
4. Operating Instructions
4.1 Battery Usage
- Connection: Connect your loads (e.g., trolling motor, RV appliances, solar inverter) to the battery terminals using appropriate cables and connectors. Ensure all connections are secure and correctly polarized.
- Parallel/Series Connection: The Group 24 size battery supports up to 4P4S configurations for increased capacity and voltage, ideal for solar systems. Consult a qualified technician for complex setups.
- Low-Temperature Protection: The integrated BMS will automatically prevent charging when the battery temperature drops below 0°C (32°F) to protect the cells. Discharging is generally permitted at lower temperatures, but performance may be reduced.
- Bluetooth Monitoring: Use the Redodo app to monitor battery status in real-time. This helps in understanding power consumption and remaining capacity.
