Making a Li-Ion 12V 3S Battery Pack (Not a tutorial!)

NOT A TUTORIAL!!!
If you want to try it on your own here's the list of the materials. But, again, this video is not detailed enough to be a tutorial.

Materials I used:
-6x 18650 cells (Li-Ion)
-DC-005 female DC power jack
-HX-3S-01 BMS board (READ THE EDIT BELOW)
-Wires
-18650 Spacers (I 3D printed them, but you can buy them if you don't own a 3D Printer)

You also need all the soldering equipment

EDIT: The module listed before is pretty terrible as far as reliability. I had 3 of them and all of 3 have failed. I'm not sure if I did something wrong. Anyways since then I replaced it with the "HX-JH-001" which has worked flawlessly for the past couple of months.

TL;DR: Get the "HX-JH-001" it's better in any way.
