Fill free to use attached Fusion 360 project
Infill-1.stl and Infill-2.stl are used for Cura slicer feature which can use these two bodies as infill adjuster.

Some info about PCB:

  • if output is more than 0.7a (for 12v output) then there is no charging
  • the discharge is stopped if battery voltage is about 3.3v
  • the charge is stopped at 4.15v
  • both charge/discharge cut off battery after stopping

More info:
First of all, the overdischarge protection is turned off at 2.4V, and the booster stops working normally already at 2.7, producing 3.3 at the output instead of 5V, for example. Well, in reality this UPS should not be loaded by more than 12W
So, we need to use protected 18650
