    Under the left rear corner of the pack is a round label:

    Under the label (uh-oh, voided) is a 6-lobe socket head cover plug:

    Behind the cover is a 2-terminal connector, which runs directly to pack + and - voltage:

    So is that plug used with jumper cables--like to jump off a car when the battery is too low?

    What is it for, and how is it used?


    It's located near the contactors:

    and at the other end of the main BMS board, but where are the 2 lithium coin cell batteries?

    That say's "High Voltage" so I would say NO!

    I believe that that is used so that Tesla can quickly drain a pack before they pull it down and open it. Since they don't like to open packs with a significant charge.) They have a large mobile power "sink" that they can plug in to that port.

    Early revisions of the pack didn't have that and they had to run the heater on full blast with the doors open for a very long time to drain the pack before they could service it.
