1. Input Power Connection:
   • Connect a 5V power source to the Micro USB port.
   • Alternatively, solder a 5V input to the designated "In the input +" and "In the input -" pads. Ensure correct polarity.
2. Battery Connection:
   • Connect the positive terminal of your 18650 lithium battery (or parallel battery pack) to the "B+" pad on the module.
   • Connect the negative terminal of your battery to the "B-" pad on the module.
   • Important: Always ensure correct battery polarity. Reversing polarity will damage the module.
3. Load Output Connection (Optional):
   • If you intend to power a load directly from the module while charging, connect your load to the "OUT+" and "OUT-" pads.
   • Caution: Do not connect the load OUT terminal with wrong polarity, as this will damage the module.

Operating Instructions

Once the module is correctly wired, charging will begin automatically when a 5V power source is connected.

Charging Process:

• Connect the 5V power supply to the Micro USB port or input pads.
• The Red LED (LED1) will illuminate, indicating that the battery is currently charging.
• When the battery reaches its full charge (4.2V), the Green LED (LED2) will illuminate, and the Red LED will turn off. This indicates that charging is complete.
• The module automatically stops charging when the battery is full, preventing overcharge.
