It uses a CC\/CV (Constant Current\/Constant Voltage) charging method, with a 4.2V charging termination voltage and a maximum charging current of up to 1A. Ideal for DIY electronics projects and portable power applications. The actual charging current depends on the module's configuration and operating temperature. Always check the battery chemistry, voltage and connection requirements before use.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eType-C USB Input:\u003c\/b\u003e Modern Type-C port for convenient and reversible connection to 5V power sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimal Charging:\u003c\/b\u003e Charges 18650 lithium batteries with a dedicated 4.2V ±1% charging termination voltage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh Charging Current:\u003c\/b\u003e Delivers up to 1000mA (1A) maximum charging current for quick and efficient charging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDual Protection Functions:\u003c\/b\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eOver-discharge Protection:\u003c\/b\u003e Automatically cuts off power when the battery voltage drops to 2.5V, preventing damage from deep discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOver-current Protection:\u003c\/b\u003e Protects against excessive current draw with a 3A over-current protection threshold.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompact Design:\u003c\/b\u003e Ultra-small board size (2.6 x 1.7 CM) makes it easy to integrate into various projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCharging Status Indicators:\u003c\/b\u003e Equipped with LED indicators to show charging status (Red for charging, Blue for fully charged).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eTechnical Specifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eInput Voltage:\u003c\/b\u003e 5V DC (via Type-C USB or solder pads)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCharging Termination Voltage:\u003c\/b\u003e 4.2V ±1%\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Charging Current:\u003c\/b\u003e 1000mA (1A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery Over-discharge Protection Voltage:\u003c\/b\u003e 2.5V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery Over-current Protection Current:\u003c\/b\u003e 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBoard Dimensions:\u003c\/b\u003e 2.6 CM x 1.7 CM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eHow to Use:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eConnect Battery:\u003c\/b\u003e Connect the positive terminal of your lithium battery to the \u003ccode\u003eB+\u003c\/code\u003e pad and the negative terminal to the \u003ccode\u003eB-\u003c\/code\u003e pad on the module.\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eImportant Note:\u003c\/b\u003e The first time you connect a battery, there might be no voltage output between \u003ccode\u003eOUT+\u003c\/code\u003e and \u003ccode\u003eOUT-\u003c\/code\u003e.
