Made a bit of progress today. These bus bars are made for both halves of the battery, just in place for a test fit now - terminals are not cleaned properly yet. I still have to make the fancy ones for the ends of the pack. It was a bit disconcerting when I realised these plates are the right size to simultaneously short out three cells at once. The lumps of foam prevent that for now, I'll probably devise something more permanent.
I want to put something between the edges of the plates and the plywood panels, the air gap is pretty small and I don't think the wood would be a perfect insulator. Maybe some tape on the edges of the plates will do.
I'm also considering whether to put in some small nuts and bolts to attach the balance leads to the centre of each plate, rather than using the cell terminal posts for this.
You can see the corner of my new 3500W inverter in this photo. Delivered to my house in NSW from Shenzen in under 7 days. It takes longer than that to get things from Brisbane or Melbourne.
