1 Circuit board PCB description：
1.1 Name ： USB C port 5V input,three series lithium battery charging management board 12.6V 1A, PW4053M chip
1.2 Applications:Convenient charging devices, etc.
1.3 Battery pack: 11.1Vlithium battery pack, multiple parallel or three series connection ， full 12.6V
1.4 Inputvoltage: 5V （ When charging, the light will be on, and when it is fully charged,the light will turn） , Max charging current ： 1A
1.5 Introduction to Chip Functions ：
1， Lithium battery charging circuit：PW4053M
PW4053M Lithium battery charge management chip， Up to 3A charging current， support three series lithium battery charging.
2， Circuit diagram ：
PCB layout is divided into two parts: signal controlcircuit + power circuit
Note 1： The blue thick line is the power trace, the layout should be wide； SW part (Q1, D1, L1 three devices connected) is not only the power output, but also it is a noise source, the layout should be wide and the area should be small.
Note 2： The red thick line is the power ground, the main points of the drawing board: to bewide, the shorter the distance between the connecting loops at each point, the more holes are punched in the ground.(input, C5, C6, C10, C9, C8,Q1 and battery ground)
