Hey Guys,
I started to design a simple 4in1 PCB for charging 18650 cells while looking at my actual charging rig attached to some wood!
Some time ago, i teached myself to design PCBs for hobby use. I really love PCB Design and started this little project.
Its a 4x Charger protected with a 3A diode and a 2A glass fuse.
I am using this for this porject:https://blog.seidel-philipp.de/xxl-powerhouse-diy-feldakku-aus-18650-zellen/

I used the cheapest components to get the lowest price possible.
Estimated costs per board including hardware:
1x PCB $4.9 (you will get 10 boards[img=16x16]https://static.xx.fbcdn.net/images/emoji.php/v9/fb0/1.5/16/1f609.png[/img])
4x TP4056 $0.74
4x glass fuse $0.11
8x glass fuse holder $0.08
4x diode $0.48
1x 18650 holder $0.90
------------------------------------
calculated price: $2.8 excluding possible shipping
real price: $7.21 and you still have 9 PCBs left to build more charges and hook them up in parallel.
What do you think?
Any ideas, tips or whiches?
These was my first design, but i already changed the cables to connect them in a better way!

Please be aware
I wont sell or ship anything to you, its a DIY project made for the community!
I will just share the files for the PCB and a list of parts used!
You have to solder andorder the PCB from any manufacturer yourself!
