5. Setup and Installation
5.1 Initial Activation and Charging
Upon arrival or after a prolonged shutdown, the battery may be in a powered-off state. To activate and ensure normal function:
- Connect the battery to a dedicated LiFePO4 charger or an MPPT solar charge controller that features a lithium activation function.
- Charge the battery for 3-10 seconds. This will turn on the battery's internal systems.
- Ensure the charger is compatible with 12.8V LiFePO4 batteries and has a 0V activation capability.
5.2 Connecting Multiple Batteries
For increased capacity or voltage, multiple Redodo LiFePO4 batteries can be connected. Observe the following guidelines:
- Connect batteries of the same brand, type, voltage, amperage, BMS, and age (within 1 month).
- For parallel connections (increased capacity, same voltage), connect positive to positive and negative to negative terminals.
- For series connections (increased voltage, same capacity), connect the positive terminal of one battery to the negative terminal of the next.
- The battery supports a maximum extension of up to 4 series and 4 parallel connections (4P4S) to achieve a 48V (51.2V) 560Ah battery bank.
5.3 Terminal Connection
When attaching OT terminals directly with screws, if the lug thickness is less than 2mm, use additional washers or gaskets for lock attachment. This prevents loosening and overheating of the connection.

6. Operating the Battery
6.1 Bluetooth Monitoring
The Redodo Smart Bluetooth 12V 140Ah LiFePO4 Battery features an upgraded smart BMS connected to a Bluetooth 5.0 module. This allows for real-time monitoring via a smartphone application.
- Download the official Redodo app from the App Store (iOS) or Google Play Store (Android).
- Ensure your phone's Bluetooth is enabled.
- Open the app and connect to your 140Ah LiFePO4 battery. The connection range is typically within 10 meters of the battery.
- Through the app, you can monitor important information such as:
- Battery Voltage
- Current (charge/discharge)
- Power (watts)
- State of Charge (SOC) / Battery Capacity
- Battery Health Diagnostics
- The app also allows for remote control functions, such as managing discharges or powering off the battery.

6.2 Low Temperature Operation
The battery is equipped with a low-temperature cut-off function for enhanced safety and longevity:
- Discharging: The battery will stop discharging if the temperature falls below -4°F (-20°C).
- Charging: Charging will be disabled if the temperature is below 32°F (0°C).
- Charging Recovery: Charging will resume when the temperature rises above 41°F (5°C).
These features protect the battery from damage in cold environments.

7. Maintenance
- Regular Inspection: Periodically check battery terminals for corrosion or loose connections. Clean terminals as needed.
- Cleaning: Keep the battery clean and dry. Use a soft, damp cloth to wipe the exterior. Do not use solvents or abrasive cleaners.
- Storage: For long-term storage, ensure the battery is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place. Avoid extreme temperatures.
- Charging: Always use a compatible LiFePO4 charger. Overcharging or undercharging can reduce battery lifespan.
- BMS Protection: The integrated 150A BMS provides protection against overcharge, over-discharge, over-current, short-circuit, and low temperature. Allow the BMS to manage these protections; do not bypass them.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not turning on/no power output. | Battery is in powered-off state (e.g., after shipping or deep discharge). | Connect to a compatible LiFePO4 charger with 0V activation for 3-10 seconds to activate the BMS. |
| Cannot connect via Bluetooth app. | Out of range, Bluetooth disabled on phone, or app issue. | Ensure you are within 10 meters of the battery. Check phone's Bluetooth settings. Restart the app or phone. Ensure battery is active. |
| Battery not charging in cold weather. | Low-temperature charging cut-off activated. | Move the battery to a warmer environment (above 32°F / 0°C) for charging. Charging will resume automatically when safe. |
| Battery stops discharging unexpectedly. | Over-discharge, over-current, or low-temperature discharging cut-off activated. | Check battery SOC via app. Reduce load. Move to warmer environment if below -4°F (-20°C). The BMS will automatically recover when conditions are safe. |
| Loose terminal connections. | Improper installation or vibration. | Tighten M8 terminal bolts. If lug thickness is less than 2mm, add washers/gaskets as described in Section 5.3. |
