Power Bank USB-C PD (Power Delivery) 100W

I wanted to build a power bank that could support the USB PD protocol so I could charge all my devices off a single battery.  I ended up with this 288 W/h power bank using 16 5000mah 21700 cells in a 4s4p configuration and leveraged a 100w USB-C PD module and 4s BMS for the build.  I used PLA because I like the way it looks but PETG may be better for heat/mounting.

Please refer the pictures for assembly.  You will need six 30mm m3 screws for the latches and hinges and two m2 screws to mount the pd module.  I also used Kapton tape for wrapping the battery pack.  Feel free to ask any questions or post suggestions/comments.

I consider this a WIP and will be adding more features.  The module gets extremely hot in and out of the case.  So far no issues with it though.  The BMS seems to stay relatively cool.
