I had almost finished the shell but I got an idea on how to make the power bank a little smaller (2 mm thinner and 4-10 mm shorter). So now I’m gonna redesign the BMS and hope that my idea will actually work without any clearance issues. And also I now have a github repo for the project so you can go take a look at the current PCB designs yourself.

I finished the lower shell part!
I ran into some issues with the button placement because I didn’t think about it when designing the main PCB. I placed the button too close to the edge of the PCB, leaving only about 3mm of space between the button and the wall of the shell, as shown in one of the pictures. Since I already have the PCB and I don’t want to order a new revision just to move the button, I will use a different button on the side of the power bank that I will solder to the original button pads with wires. It’s probably not the best solution, but it should work.

So I had to resolder the main PCB because I ripped a pad off a IC while trying to reflow it. I learned the hard way that capacitors also don’t like being on a hot plate for too long. I ended up burning most of them. Now I have to wait for new capacitors before I can fully assemble the PCB.

First devlog on my power bank. Just finished the battery holder in cad. Next will be the lower shell part.
