Rear charging and terminal enclosures
Concurrently with the layout and fab of the battery boxes, both front and rear terminals were located. It was a challenge to fit everything in. Especially since I didn't know the sizes of items having never done this before. So it was a great deal of hurry up and wait, while I looked for orders to arrive to allow configuring the boxes. (Wow, are the fuses really that BIG??)
The rear enclosure was located just above the 12V battery, and housed gang terminals for attaching to the low volt requirements. It also housed higher voltage, lower amperage conductors associated with the DC-DC 12V charging system (ie, enable relay for that system). Not least of the installation was the Master Control Unit for the battery management system (BMS). More on that later.
The rear pack contactor was located separately in its own enclosure. Had the battery packs been over 60 volts, the contactor would have had to be located within the battery box. (obscure US Govt regulation). An inertia switch was located on the RH rear fender bulkhead to cut off control power in the event of a collision.
