Power Bank Case 100W (Remix)

This is a remix of tearandfix's 8 cell 21700 battery bank model, but with the following changes:

• instead of using clips to attach the two pieces it uses plastic screws (M3*12mm plastic screws from this kit)
• it uses a different power bank module 

Here is the link to the power bank module, but since aliexpress links often die I will enclose the products title so you can search it, also there is a screen shot of the aliexpress page as well, make sure that you get the 4s version or read the documentation and use the switches to set it to 4s.

Credit for the remix of this design goes to Nasir R on Fiverr.

The wiring is basically the same as the original model by tearandfix. Make sure to spot weld the batteries according to images in tearandfix's og post.

I would like to mention a flaw that I have found in this and the og power bank model is that if you plug more than one device into them then it can not input or output at pd levels only at 5v. I think this happens because they wire all the ports to the same pd chip, but I am just guessing.
