This is the proposed layout for the boards and wiring inside the battery box.
Please add your comments if you have any!
When making the diagram, a few things were noted:
GND contactor will be shifted RIGHT to allow more room for LV wires
BMS Carrier will be shifted DOWN in order to allow more room for the wiring around it
AUX battery will be shifted LEFT to allow more room for the wires around the leftmost AFE
