Operating Instructions
Follow these steps carefully to charge your 16S 60V Lithium Battery Pack:
- Connect to Battery First: Before connecting the charger to AC power, ensure the DC output terminal of the charger is securely connected to the battery's charging socket.
- Connect to AC Power: After the DC terminal is connected to the battery, plug the AC power cord into a standard 100-120Vac, 50-60Hz wall outlet.
- Monitor Charging: Observe the LED indicators and the OLED display for charging status.
- Disconnect After Charging: Once charging is complete (LED 2 turns green), first unplug the AC power cord from the wall outlet, and then unplug the DC terminal from the battery.
- Storage: When not in use or after charging, always unplug both the DC terminal from the battery and the AC terminal from the wall outlet.
LED Indicator Guide
- LED 1 (Red): Indicates that the charger is powered on.
- LED 2 (Red): Indicates that the battery is currently being charged.
- LED 2 (Flashing Red): Indicates that the battery is nearing a full charge.
- LED 2 (Green): Indicates that the battery has been fully charged.
OLED Display Information
The OLED display provides real-time data during the charging process:
- Voltage (V): Displays the current charging voltage.
- Current (A): Displays the current charging amperage.
- Temperature (°C): Displays the internal temperature of the charger.
- Power (W): Displays the current charging power in watts.
Maintenance
- Cleaning: Regularly wipe the charger's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure the cooling fan and ventilation slots are free from dust and debris to maintain optimal heat dissipation.
- Storage: Store the charger in a cool, dry place when not in use, away from extreme temperatures and humidity.
- Fuse Replacement: If the charger stops functioning, check the fuse. Refer to the "Troubleshooting" section for instructions on replacing the fuse.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on (LED 1 off) | No AC power; Loose power cable; Blown fuse. | Check wall outlet and power cable connection. Replace fuse if necessary (refer to fuse replacement instructions below). |
| LED 2 remains red, battery not charging | DC connector not properly connected to battery; Battery fault. | Ensure DC connector is firmly seated. Check battery for issues. |
| Charger gets excessively hot | Poor ventilation; Overload. | Ensure charger is in a well-ventilated area. Clear any obstructions from cooling fan/vents. Ensure battery is compatible. |
| OLED display is blank or erratic | Power issue; Internal fault. | Check power connection. If problem persists, contact customer support. |
