Kurulum Talimatları
Follow these steps to set up your UMLIFE charger board:
- Bağlantı Noktalarını Belirleyin: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.

Resim: Yukarıdan aşağıya view of the charger board. This image clearly shows the input (IN+, IN-), battery (B+, B-), and output (OUT+, OUT-) connection points, which are crucial for proper wiring.
- Pili bağlayın: 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.
- Yükü Bağla (İsteğe Bağlı): 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.
- Güç Kaynağını Bağlayın: 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.
- Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.
Kullanım Talimatları
Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:
- Şarj Göstergesi: 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 voltag(4.2V).
- Eğer pil hacmitage 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.
Koruma Özellikleri:
The board includes an integrated protection circuit to safeguard the battery and the module:
- aşırı sestage Koruma: Pilinin güvenli voltaj sınırının ötesinde şarj edilmesini önler.tage sınırı.
- Aşırı Deşarj Koruması: Prevents the battery from discharging below 2.4V, extending battery life.
- Aşırı Akım Koruması: Limits the output current to 4A to prevent damage from excessive load.
Bakım
To ensure the longevity and proper functioning of your charger board:
- Keep the board clean and free from dust and debris.
- Levhayı neme veya aşırı sıcaklıklara maruz bırakmaktan kaçının.
- Kısa devreleri önlemek için tüm bağlantıların güvenli ve uygun şekilde yalıtıldığından emin olun.
- Belirtilen giriş hacmini aşmayıntage range (5V-6V) or output current (1A charging, 4A protection limit).
