Produkt überview

The UMLIFE Ultra-mini USB Type C Lithium Battery Charger Board is designed for charging 3.7V lithium batteries. It features a compact design, a Type-C USB input for power supply, and integrated protection circuits to ensure safe charging. This module is compatible with most PD fast charging heads and provides a 1A linear charging current.

Zu den Hauptmerkmalen gehören:

• Ultra-small form factor for integration into various projects.
• USB Type-C input for convenient power connection.
• 1A high current linear charging for 3.7V lithium batteries.
• Integrated protection circuit for over-voltage, Tiefentladungs- und Überstromschutz.
• LED-Anzeigen für den Ladestatus.

Installationsanweisungen

Follow these steps to set up your UMLIFE charger board:

1. Verbindungspunkte identifizieren: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.

2. Batterie anschließen: 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. Last anschließen (optional): 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. Stromversorgung anschließen: 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.

Bedienungsanleitung

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

• Ladeanzeige: 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 (4.2 V).
• Wenn die Batterieladungtage 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.

Schutzfunktionen:

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

• Überlautstärketage Schutz: Verhindert, dass der Akku über seine sichere Ladespannung hinaus geladen wird.tage Grenze.
• Überentladungsschutz: Prevents the battery from discharging below 2.4V, extending battery life.
• Überstromschutz: Limits the output current to 4A to prevent damage from excessive load.

Wartung

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

• Halten Sie das Board sauber und frei von Staub und Schmutz.
• Vermeiden Sie es, die Platine Feuchtigkeit oder extremen Temperaturen auszusetzen.
• Stellen Sie sicher, dass alle Verbindungen sicher und ordnungsgemäß isoliert sind, um Kurzschlüsse zu vermeiden.
• Überschreiten Sie nicht die angegebene Eingangslautstärketage range (5V-6V) or output current (1A charging, 4A protection limit).
