3. Persediaan
- Sambungkan Kuasa: Connect the provided Type-C cable to the charger's input port (IN: 5V/2A) and plug the other end into a 5V/2A USB power adapter (not included). The charger's LEDs will light up instantly.
- Penyesuai Kuasa: Ensure your power adapter provides 5V/2A for optimal charging performance.
4. Arahan Operasi
4.1. Mengecas Bateri
- Masukkan Bateri: Place a rechargeable battery into any of the four independent charging slots, ensuring correct polarity (+/-).
- Pengesanan Automatik: The charger will automatically detect the battery type (Li-ion or NiMH) and its voltage. The LEDs will flash, indicating the battery type setting.
- Select Battery Type (Li-ion only): For Li-ion batteries, if the detected voltage is not what you intend (e.g., 3.7V vs 3.85V), you can short press the 'MODE' button within 5 seconds of insertion to cycle through the Li-ion voltage options (3.2V, 3.7V, 3.85V). The NiMH 1.2V mode cannot be manually selected for other battery types.
- Select Charging Current: For slots 1-3, you can adjust the charging current by long pressing the 'MODE' button for 2 seconds to cycle through 500mA, 700mA, 1000mA, and 2000mA. Slot 4 is fixed at 2000mA for fast charging.
- Pengecasan Monitor: The 4 LED indicators (25%, 50%, 75%, 100%) will show the real-time charging progress. When all 4 LEDs are solid, the battery is fully charged.
4.2. Using USB Output (Power Bank Function)
The Lii-402 can function as a portable power bank to charge external devices via its USB output port (OUT: 5V/1A).
- Masukkan Bateri Bercas: Ensure at least one fully charged Li-ion battery (e.g., 18650, 21700) is inserted into any slot.
- Sambungkan Peranti: Plug your device's USB charging cable into the charger's USB output port.
- Mula Mengecas: The charger will automatically begin supplying 5V/1A power to your device.

5. Penyelenggaraan
- Keep the charger clean and dry. Avoid exposure to moisture or extreme temperatures.
- Jangan cuba membuka atau mengubah suai pengecas.
- Simpan pengecas di tempat yang sejuk dan kering apabila tidak digunakan.
- Regularly check the charging slots and contacts for any debris or corrosion.
6. Penyelesaian masalah
- Pengecas tidak dihidupkan: Ensure the Type-C cable is securely connected to both the charger and a functional 5V/2A power adapter. Try a different cable or adapter.
- Bateri tidak dicas: Check battery polarity. Ensure the battery is compatible with the charger. If the battery is deeply discharged (0V), the charger has a 0V activation function, but some extremely low voltage batteries might not be recognized.
- LEDs flashing abnormally: This might indicate a faulty battery or an error. Remove the battery and reinsert it. If the issue persists, the battery might be damaged.
- USB output not working: Ensure a sufficiently charged Li-ion battery is inserted. The USB output requires power from an inserted battery.
7. Maklumat Keselamatan
⚠️ Sila ambil perhatian tentang potensi risiko kebakaran dan ikuti manual arahan untuk pengecasan dan penyimpanan dengan ketat.
- Perlindungan Lebihan: Automatically stops charging when batteries are full.
- Perlindungan lebihan pelepasan: Prevents batteries from being discharged too low when used as a power bank.
- Perlindungan Litar pintas: Melindungi daripada litar pintas.
- Perlindungan Polariti Terbalik: Prevents damage if batteries are inserted incorrectly.
- Vol. 0Vtage Activation Function: Can activate deeply discharged batteries.
- Intelligent Identification of Bad Battery: Helps detect and prevent charging of damaged batteries.
- Penggunaan Dalaman Sahaja: This charger is designed for indoor use. Do not expose to rain or moisture.
- Jangan cas bateri yang tidak boleh dicas semula.
- Jauhkan daripada kanak-kanak.
8. Petua Pengguna
- For faster charging of a single battery, use slot 4 which provides a fixed 2000mA current.
- When using the USB output, ensure the inserted Li-ion battery has sufficient charge to power your external device effectively.
- Always double-check the battery type and voltage selection for Li-ion batteries to ensure proper charging and prevent damage.
- If you have multiple batteries to charge, consider using lower current settings (e.g., 500mA or 700mA) for a gentler charge, which can prolong battery life, especially for smaller capacity batteries.
