Somewhere there should be some pictures of the Battery Management System, but I can't find them at the moment.

I have some BMS pictures I sent to MM one time. I'll have to look for them when I get a chance. Unless Monkey uploads them.

I've attached a modified picture showing what I think is the connecting layout for the thirteen groups of three paralleled cells.
You'll have to ignore the duplicated balance leads where I have copied and pasted in order to show all the cells.
There should be a total of twelve balance leads, one connected to each of the white interconnecting links:

But now I'm not sure whether it might even be wired like this:
