The finish-ish of a pcb based 14S 80P powerwall
Very nice, I wish I just new how to design a PCB  to be able to do somthing like this with my cells.. I’ve got cells scattered EVERYWHERE!!

Have a look in the Downloadable Resources section. Also Grumble uploaded his gerber files in Post 83. You need only upload them to a custom PCB manufacture, and they will make them for you. (Try JLPCB) No CAD skills required.

What is Powerwall? how to build? I'm from Brazil.

Hi Romo,
welcome aboard! powerwall is a stupid expression for battery. It is used by people who want to sound cool (or so they think) but mostly have no clue what they are talking about.
For the rest, just read the posts and threads for a couple of weeks and you will be much wiser without asking question which are already answerd by someone who already went through the trouble.

As for the pcb design. Instead of ordering the backplanes in 2oz, which is very expensive compared to regular 1oz, I'd order 1oz. If need be, I would rather then reinforce the back layer with desolder mesh copper wire or other such things. Maybe add a couple of solder pads to the backplane in the pcb design (no stop mask). Comes out a lot cheaper this way. You are welcome!
And, if you wonder, the solder pads have to be added in the actual desing file. I dont know any program that will allow you to change the gerber file directly. So maybe gramble has a few hours to spare.

Many, but can't be bothered to save you even more money.

not my money. But you could save a few bucks/quit by the next extension of your battery. I have my own pcb design. Very cost effective. Been testing for a couple of month and assembling a prototyp as we speak. Might or might not lay it open to a later time. It is a a bit like your design and a bit like the design jehu uses. My own idea I must say. BTW. Jehu did not make the pcb design. Its not his pcb design, as he mentioned in the first couple of his pcb videos and never bothered to mention later. So, generaly, please people, do not say "jehu´s design".

Get a free copy of KiCAD and get started. Most common pcb design software. Check regularly for updates, since they come often. Intro pages and tutorials on their web site and on Youtube are plenty. It is open source and free.
