2Pcs Type-C Microcontroller 18650 Lithium Battery Charger 1.8V 3.3V 5V Power Supply Module

Product Description

This module can supply power to the microcontroller through a 3.7V 18650 lithium battery and a Type-C USB port input 5V power supply. It can also be used to supply power to modules with appropriate electrical parameters (cannot be directly connected to a motor). At the same time, the module also has UPS function. When the TYPE-USB input is disconnected, the module continues to output. The module outputs three different voltages of 5V, 3.3V, and 1.8V in the form of 2.54mm spaced pins, which can be used as a power supply in various scenarios. The module is equipped with 2 charging indicator lights to indicate the current charging status. Indicator light description: The red light is on during charging; Full of green lights on.  Parameter Introduction 1. USB port input voltage: 5V 2. Suggested battery operating voltage: 3.2-4.2V 3. Battery fully charged voltage: 4.15-4.25V 4. Battery overdischarge detection: 2.4V 5. Maximum output current: 5V: 1.8A 3.3V: 400mA 1.8V: 150mA 6. Charge and discharge simultaneously: The output voltage is 5V, and the maximum output current is affected by the input current of TYPE-C port. It is recommended to output a maximum of 1.8A 7. Battery connection method: Parallel connection (batteries can be connected to one or two)  Don't look at the instructions inside the battery box, look at the battery direction indicators on the PCB. The two batteries are connected in parallel to the module, and the positive pole of the battery is connected towards the USB port direction.
