4. Setup
4.1 Initial Activation
For the first use, or if the battery has been switched off (voltage below 10V), it needs to be activated. Connect the battery to a compatible lithium-activation charger or an MPPT solar charge controller. The battery will activate automatically upon receiving a charge.
4.2 Connecting the Battery
- Ensure all connections are clean and free of corrosion.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/system.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/system.
- Use the provided M8 screws and washers to secure connections tightly. Apply insulation caps over the terminals for added safety.
- For 24V or 36V systems, connect multiple batteries in series as required (2 batteries for 24V, 3 batteries for 36V). Ensure all batteries are of the same voltage and capacity when connecting in series or parallel.

6. Maintenance
6.1 Charging
Always use a LiFePO4 compatible charger. Ensure the charger's voltage and current settings are appropriate for a 12V 100Ah LiFePO4 battery. Avoid overcharging or undercharging. The integrated BMS will manage charging parameters, but using a dedicated LiFePO4 charger is crucial.
6.2 Storage
If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC). Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. Periodically check the battery's SOC during storage and recharge if necessary.
6.3 Cleaning
Keep the battery terminals and casing clean and dry. Use a dry cloth to wipe away any dust or debris. If corrosion is present on terminals, clean with a wire brush and a baking soda solution, then rinse with distilled water and dry thoroughly.
7. Troubleshooting
- Battery Not Activating: If the battery voltage is below 10V, connect it to a LiFePO4 charger with an activation function or an MPPT solar charge controller.
- Bluetooth Connection Issues: Ensure Bluetooth is enabled on your device and the LiTime app has necessary permissions. Try restarting the app or your device. Ensure you are within range of the battery.
- No Power Output: Check all cable connections for tightness and proper polarity. Verify the battery's State of Charge via the app. If the battery is too cold, low-temperature protection may be active (refer to section 5.3).
- Reduced Performance: Ensure the battery is fully charged. Check for any error codes or warnings in the LiTime app.
For further assistance, refer to the LiTime app for detailed diagnostics or contact customer support.
