Konfigurazio Argibideak

Follow these steps to set up your UMLIFE charger board:

  1. Konexio puntuak identifikatu: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.

  2. Konektatu bateria: Connect your 3.7V lithium battery to the B+ and B- pads. Ensure correct polarity: B+ to the positive terminal of the battery, and B- to the negative terminal.
  3. Karga konektatu (aukerakoa): If you intend to power a device directly from the charger board while charging, connect your load to the OUT+ and OUT- pads. Note that the "Battery+" and "Output+" terminals are electrically bonded together. The "Output-" and "Battery-" terminals are electrically isolated.
  4. Konektatu elikadura iturria: Insert a USB Type-C cable into the board's Type-C port. Connect the other end of the cable to a 5V to 6V USB power source, such as a mobile phone charger or a compatible PD fast charging head.
  5. Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.

Funtzionamendu-argibideak

Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:

  • Kargatzeko adierazlea: A red LED typically indicates that the battery is currently charging.
  • Charged Indicator: A green or blue LED typically indicates that the battery is fully charged.

Charging Cycle Behavior:

  • The charging cycle automatically terminates when the charging current drops to 100mA after reaching the final float voltage (4.2V).
  • Bateria boltage drops below 4.05V (approximately 80% to 90% of capacity), the charging cycle will automatically restart.
  • For batteries with voltage below 2.9V, the board initiates a pre-charge phase with a current of 100mA.

Babes-ezaugarriak:

The board includes an integrated protection circuit to safeguard the battery and the module:

  • Bolumen gehiegitage Babesa: Prevents the battery from being charged beyond its safe voltage muga.
  • Deskarga gehiegizko babesa: Prevents the battery from discharging below 2.4V, extending battery life.
  • Gainkorrontearen babesa: Limits the output current to 4A to prevent damage from excessive load.

Mantentzea

To ensure the longevity and proper functioning of your charger board:

  • Keep the board clean and free from dust and debris.
  • Avoid exposing the board to moisture or extreme temperatures.
  • Ziurtatu konexio guztiak ondo isolatuta daudela eta zirkuitulaburrak saihesteko.
  • Ez gainditu zehaztutako sarrera bolumenatage range (5V-6V) or output current (1A charging, 4A protection limit).
