Leaf Lithium battery pack/box build basic questions

[somfas]

I am building the battery pack and want to confirm a few things first.

1. do the modules need any plates between them? I have the factory end plates (4 of them), and I have thin strips that seem to be placed between some modules based on pics I have seen on here. But I don't see the need for them.

2. I assume the modules naturally stack together with opposing terminals near each other (so that I can connect the small bus bars from positive to negative).

3. Does anyone have a diagram or pic of how to run the bus bars and the wiring for the BMS? I want to make sure I am hooking that part up right!!!

Thanks
