Leaf Lithium battery pack/box build basic questions
 
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

Attached is a basic drawing of a 7 module 14S pack. This wiring applies to the Ali Express BMS on the leaf modules. It was originally drawn for the BMS from EV Battery Center before Nick passed away. I have others for a ZEVA BMS.

No plates need between modules.

What cart is this going into?

Pics are of an assembled pack

Wow, that looks nice PingEye! Thanks about clarifying about the plates between the modules. I see, even in the pictures above, three studs on the modules; two of which are being used to hold the wire clamps. I thought those were part of some brace but I suppose they are built onto some of the batteries? Mine is going into an EzGo. I suppose you have to make all of the wiring including the larger cables? Thanks again.

I may have missed your build thread... what is the source of the box in your pack ? You built it, or somebody sells these ? Thanks!
