I decided to make my portable power bank with PD using IP2368. I used 4 batteries 18650 connected in series. The battery balancing board must be attached to the battery holders.
No bushings are required! You will need a few screws:
It is preferable to print it with PETG or another material with a higher melting temperature because the IP2368 board heats up at high power.
I have uploaded GCODE files for PLA and PETG.
