5. Configuración
5.1 Conexión de alimentación
- Potencia CA: Connect the AC power cord to the charger's AC input port, then plug the other end into a standard wall outlet (100-240V AC).
- Potencia CC: Alternatively, connect the DC input cable (with alligator clips) to the charger's DC input port. Connect the red clip to the positive (+) terminal and the black clip to the negative (-) terminal of a 11-18V DC power source (e.g., a 12V car battery).
The charger will power on, and the LCD screen will illuminate.
5.2 Conexión da batería
- Connect the appropriate charging lead (e.g., Banana plug to Deans adapter) to the charger's main output terminals (red to red, black to black).
- Connect the other end of the charging lead to your battery's main power connector.
- For LiPo, LiHV, Li-Ion, or LiFe batteries, also connect the battery's balance lead to the appropriate slot on the JST-XH balance adapter board, then connect the adapter board to the charger's balance port. Ensure the correct cell count slot is used.
6. Instrucións de funcionamento
6.1 Navegación por menús
Usa o BATT/PROG button to cycle through the main battery program types. Use the Status / Decrease e Start / Enter buttons to navigate within menus and adjust values. Press Start / Enter to confirm a selection or start an operation. Press Pare to go back or end an operation.
6.2 Charging LiPo/LiHV/Li-Ion/LiFe Batteries
- Connect the battery as described in Section 5.2.
- Preme BATT/PROG until the desired battery type (e.g., 'LiPo BATT') is displayed.
- Preme Start / Enter to enter the LiPo program menu.
- Select the desired mode (e.g., 'LiPo BALANCE CHG' for balanced charging, 'LiPo CHARGE' for fast charging, 'LiPo FAST CHG' for fast charging, 'LiPo STORAGE' for storage charge). Balanced charging is recommended for optimal battery life and safety.
