3. Specifiche

4. Configurazione e cablaggio

The module can be powered via its Type-C interface or by directly soldering wires to the input pads. Ensure all connections are secure and follow the polarity indicated on the board.

4.1. Connessione in ingresso

• Ingresso di tipo C: Connect a compatible Type-C power source (4.5V-15V) to the Type-C port on the module.
• Soldered Wire Input: Solder input wires to the IN+ E IN- pads. Ensure correct polarity.
• Fast Charging Input: If using a fast charging source, configure the input voltage:
  • For 2-string battery configurations: Set input to 9V.
  • For 3 or more string battery configurations: Set input to 12V.

4.2. Collegamento della batteria

• Connect the lithium battery pack to the B+ E B- cuscinetti.
• Importante: The battery pack MUST include a protection board.
• Ensure the battery is connected with correct polarity (B+ a positivo, B- a negativo).
• The module supports 1-5 series lithium batteries or lithium iron phosphate batteries.
• Il volume di caricatage can be adjusted by resistors on the module to match the specific string configuration (e.g., 8.4V for 2S, 12.6V for 3S, 16.8V for 4S).

4.3. Controllo iniziale

• Before connecting the battery, connect the charging head (power source) to the module.
• Verify that the module's charging indicator light displays normally.

5. Istruzioni per l'uso

Once properly connected, the module will automatically manage the charging process.

5.1. Processo di ricarica

• The module employs an intelligent three-stage charging process: pre-charge, constant current, and constant voltage.
• It automatically switches between boost and buck modes to optimize charging based on input and battery voltages.

5.2. Indicatori LED

The 3-color LED provides visual feedback on the charging status:

• Ricarica: Indica che la batteria è attualmente in carica.
• Pieno: Indicates the battery has reached its full charge capacity.
• Ricarica rapida: Indicates that fast charging protocol is active.

6. Manutenzione

• Gestione del calore: When the module operates at high power, it will generate heat. Ensure adequate ventilation or consider fanning the module. Avoid enclosing the module in materials that do not dissipate heat effectively.
• Integrità del cablaggio: Regularly inspect all soldered connections and wires to ensure they are secure and not too thin, which could impede charging current.
• Pulizia: Keep the module free from dust and debris to ensure optimal performance and heat dissipation.

7. Risoluzione Dei Problemi

Q: What fast charging protocols does the product support?

A: The module primarily supports the common QC (Quick Charge) protocol, which is compatible with most fast charging sources available on the market.

Q: Does the module generate a lot of heat during operation?

A: The amount of heat generated by the module is directly related to the charging power. When operating at relatively high charging power, it is normal for the module to generate a noticeable amount of heat. Ensure proper ventilation as mentioned in the Maintenance section.

Q: The charging indicator light is not working or charging is not occurring.

A:

• Check all wiring connections for correct polarity and secure soldering.
• Ensure the input power source is within the 4.5V-15V range and is functioning correctly.
• Verify that the battery pack has a protection board.
• Confirm that the battery is not connected in reverse.
• Ensure the charging head was connected before the battery.

8. Suggerimenti per l'utente

• Always use a battery pack equipped with a protection board to prevent overcharge, over-discharge, and short circuits.
• For optimal performance and safety, ensure that all wires used for connections are of appropriate gauge and are securely welded. Thin wires can restrict current flow and cause issues.
• When integrating the module into an enclosure, design for adequate airflow to prevent overheating, especially during high-power charging cycles.
• If you are unsure about the correct voltage settings for fast charging, start with a standard 5V input and gradually increase if your battery configuration and power source support it.
