#WARNING⚠️⚠️⚠️
    -The chip must use the standard version, IP5358_BZ
    -Online Many sellers sell incorrect versions of chips, so be sure to carefully consider the store where you buy it
    - if you buy the wrong chip, it will have different functions, there may be logic failures, and it may even not work properly
    - before you find a formal purchasing channel It is recommended not to copy this project
    - the peak current of the battery terminal is above 5A, be sure to ensure the current carrying capacity of the battery
    - the connecting cable used must ensure the carrying capacity, otherwise the motherboard will report an error or even burn the board at high temperature
 
#Supplementary instructions
    - Please see B for production details Website video content
    - the outer shell is real cola skin
    - the internal container is 3D printed (it is recommended to use 3D Monkey), the 3D model is in the git warehouse
    - I am not the original author of this idea, this project is a motherboard with fast charging function designed after communicating with the original author
    -The author's original power bank is relatively simple to make, but it does not support fast charging! There is also the original content in the git repository
