Notes on use :


1 The output voltage of the charging port is a pulsating voltage, for example: the output voltage of the 8.4V version is 8-10V pulsating.


2 If the battery quality is relatively poor, sometimes it will cause continuous charging. At this time, you can reduce the resistance of R1 and lower the charging voltage.


3 When the battery is fully charged or not connected to the battery, the CR light is off.







Applications:

PDA, MP3 Players, MP4 Players
Digital Cameras
Bluetooth Applications
Game Players
Notebook
Li-on Li-po
Lithium Battery 18650


Mobile phone
Solar charging
Audio equipment
Portable Devices
POS , Electric Fan
TYPE-C Charging Cquipment












The input current is determined by the value of the two RCS


The charging voltage can be changed by changing the resistance of R1


Charging Voltage = 1.205*(1+R1(KΩ) = 10*(Vcharg/1.205 -1)
