You can currently install 20 18650 cells. They are extremely well protected in this case.

I used old 18650 batteries to build a QC3.0 charging station.
The pcb from Aliexpress:

(Housing upload soon)

I used battery spring plates for the wiring.
Amazon:

And I soldered them to stiff installation wire with 1.5mm2.
Because I don't have a spot welder.

(U need M3 (or M2,5 from old laptop) screws.


I'll be drawing more modules for expansion soon.
