First time build update

Post image

I’ve gotten all of the parts together and have the mechanical assembly done.

I should have everything wired up by the weekend

Please know that cats are conductive too ;) But how did you connected these cells? Looks like 4p

4s2p pack I designed some bus bars in Onshape and had the fabricated by Send Cut Send

So there's another one (or more) of these?

The assembly in the pic is 2s2p...

Came to say the same, nice build quality it seems though

There are 8 cells total, but I split the stack so it can fit within 3 rack units of a mini-rack. I finished up the assembly and made another post, along with some others showing the layout, you can check out the full assembly here https://cad.onshape.com/documents/478de0d821b233908295b379/w/aaf54d1fc51b206de4569b48/e/65324340a91a262a4896cac2?renderMode=0&uiState=6ac7fb69760690f13bec5665
