3. Setup

1. Power Source Connection: Connect the Type35 charger to a compatible USB-C Power Delivery (PD) power source. Ensure the power source can provide 9-20V and up to 35W output for optimal performance. This can be a wall adapter or a power bank.
2. Battery Connection: Identify the balance port on your 2-4S LiPo, LiHV, or LiFe battery. Connect the battery's balance lead directly to the corresponding balance port on the Type35 charger. No additional connectors are needed.
3. Initial Check: Once connected, the charger's LED indicators will provide feedback on its status.

4. Operating Instructions

The Type35 charger uses a tri-color LED system to indicate its operational status. Refer to the table below for detailed explanations of each LED state.

5. Maintenance

• Keep the charger clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the charger to moisture or extreme temperatures outside the specified operating range (0°C~40°C).
• Store the charger in a dry place with a humidity level between 5%~75% RH (non-condensing) and a temperature between -10°C~70°C.
• Regularly inspect the USB-C port and battery balance port for any signs of damage or wear.
• Do not attempt to open or modify the charger, as this will void the warranty and could lead to malfunction or injury.

6. Troubleshooting

If you encounter issues with your Type35 charger, refer to the LED indicator table in Section 4 for guidance. Common issues and their solutions are:

• Blinking Red Warning LED: This indicates a problem with the battery connection or an abnormal cell voltage (too high or too low). Ensure the battery's balance lead is securely connected to the charger. Check the battery's condition and individual cell voltages if possible.
• Solid Red Warning LED: The input voltage from your USB-C PD power source is lower than the battery voltage. Ensure your power source is providing adequate voltage (9-20V) and current for the battery being charged.
• Solid Yellow Warning LED: The charger is experiencing over-temperature protection. Disconnect the charger and allow it to cool down in a well-ventilated area before resuming operation. Ensure there is adequate airflow around the charger during use.
• Charger Not Responding: Ensure the USB-C PD power source is active and providing power. Try a different USB-C cable or power source if available.
