18650 Powerbank (2-10 cell)
cults3d
This is a simple Powerbank using standard 18650 lion cells and <3$ charging Module. All you have to do is put the cells in th same direction and solder the contacts (all positive pole together and all minus pole together) I have a spot welder, but if you carefully solder wires over the contacts that will also work. WARNING! Allow batteries to get too hot or connecting them incorrectly can be extremely dangerous. Batteries can catch fire or even explode. If you have doubts that you can assemble this yourself, look for a specialist! I'm using this charging module: https://de.aliexpress.com/item/32859845791.html?spm=a2g0s.9042311.0.0.2b364c4drgaQ07 I have files for 2, 4, 6, 8, and 10 cells available for download. On the photos is the largest variant with 10 cells. The frame for the display needs a few drops of glue
