PowerBank case (3s3p) v2

Description

Just another one PowerBank. I chose 3s3p (12.6v) for QuickCharge function. You can find these modules on Aliexpress by word "CKCY U1B" or just "DC-DC step-down converter with QuickCharge function". Available FreeCAD source, so you can customize it for your purpose.
