Final assembled pack core

Final assembled pack core
lithium pack core assembly

The main threaded rod clamps were tightened, and the insulating strips were hot glued in position so they can't slide out. The 3 main plates will be the attachment to the outer pack, and each had 5 # 8 screws, which should make a very secure attachment.
Next I need to make the large Fiberglas mounting plate to secure the connections, and give me a way to connect the BMS wiring.
the pack core is 11.5" wide, 16.5" long, 9" tall have not weighed it yet.
