5. Arahan Persediaan

Ikuti langkah ini untuk menyediakan pengecas anda:

1. Connect the DC Output Cable: Connect the DC output cable (with Anderson connector, or attached M8 O-shaped terminals/alligator clamps) to your 24V LiFePO4 battery. Ensure the positive (+) terminal of the charger connects to the positive terminal of the battery, and the negative (-) terminal of the charger connects to the negative terminal of the battery.
2. Connect the AC Input Cable: Plug the AC power cord into the charger's AC input port.
3. Sambung ke Alur Kuasa: Plug the other end of the AC power cord into a standard 100-240V AC wall outlet.
4. Sahkan Sambungan: Double-check all connections to ensure they are secure and correctly polarized before proceeding.

6. Arahan Operasi

Once properly connected, the charger will automatically begin the charging process. Monitor the LED indicators for status updates.

6.1 Penunjuk LED

The charger features LED indicators to display its operational status:

• LED1 (Red) / LED2 (Red): Pengecasan sedang dijalankan.
• LED1 (Green) / LED2 (Green): Battery fully charged or charger in standby mode (no battery connected).
• LED1 (Red, flashing) / LED2 (Red, flashing): Charger malfunction or protection function activated.

6.2 Three Charging Stages

The charger utilizes a smart 3-stage charging process to optimize battery life:

1. Stage 1: Pre-charge (T1): If the battery is deeply discharged, the charger will apply a gentle trickle charge to activate the battery and safely raise its voltage. This protects both the charger and the battery from sudden stress.
2. Stage 2: Constant Current (CC) (T2): Once the battery's voltage is within a safe range, the charger delivers its full rated current (20A) to rapidly charge the battery.
3. Stage 3: Constant Voltage (CV) (T3): As the battery approaches full charge, the charger maintains a constant voltage while gradually reducing the charging current. This prevents overcharging and ensures the battery is fully and safely charged.

7. Penyelenggaraan

To ensure the longevity and optimal performance of your Redodo charger and batteries:

• Keep the charger clean and dry. Avoid exposure to moisture, dust, and extreme temperatures.
• Simpan pengecas di tempat yang sejuk dan kering apabila tidak digunakan.
• If the battery is not used for an extended period, it is recommended to recharge it every 3 months to maintain its health.
• Regularly inspect cables and connectors for any signs of wear or damage. Replace if necessary.

8. Penyelesaian masalah

Jika anda menghadapi masalah dengan pengecas anda, rujuk kepada masalah dan penyelesaian biasa berikut:

• Pengecas Tidak Dihidupkan:
  • Check if the AC power cord is securely plugged into both the charger and the wall outlet.
  • Sahkan bahawa soket dinding berfungsi.
• Battery Not Charging / Fault LED Flashing:
  • Ensure the DC output cable is correctly connected to the battery terminals (positive to positive, negative to negative).
  • Periksa sebarang sambungan yang longgar atau kabel yang rosak.
  • The battery's Battery Management System (BMS) might have shut down due to deep discharge (voltage below 18V for a 24V battery).
  • For deeply discharged 24V batteries (below 18V): Disconnect all devices from the battery and let it rest for 30 minutes. If the voltage recovers above 20V, proceed with normal charging. If not, use a charger with a lithium battery activation function (like this Redodo charger's pre-charge mode) or connect it to a solar charge controller for 3-10 seconds to attempt activation.
• Pengecas Terlalu Panas:
  • Pastikan pengecas berada di kawasan pengudaraan yang baik dan tidak bertutup.
  • Check if the cooling fan is obstructed.
