Added a few more pictures, to show some progress, I am expecting my ATX power adapter soon. I'm just hoping I have the right dimensions for the PCB mountable spade terminals. After the several reworks and restarts I did today to get as far as I did I'll be needing more practice at that aspect of these projects as well.

As you will see in the photos my solder skills have seriously depreciated in the past 20 some years, but this project should get that skill back in shape.

What I did get done was to solder the wires that will go from the TP4056 boards to the power distribution board on the charging tray.
