Description
I created a Powerbank for 18650 Liion.
Most parts are recycled parts:
3x 18650 Liion (in my case 2400mAh)
1x step up module 5V
1x connector cable (in my case a micro usb)
3x M3x20 screws
The cell package is spot welded. See my Spotwelder case for the cheap banggood spot welder.
Have fun!!
