Not a 12v battery junction box as I read it, but a HV junction box.
From what I have read on this forum, the HV battery is 9 modules which vary among the SR, ER and Flash capacity batteries:
480 cells = 131 kwh battery in the ER (8 x 55 + 1 x 40) or 96 series groups of 5 parallel cells
450 cells = 123 kwh battery in the Flash (6 x 55 + 3 x 40) or 90 series groups of 5 parallel cells
360 cells = 98 kwh battery in the SR (9 x 40) or 90 series groups of 4 parallel cells
They all have 9 modules and the 9 modules all take up the same physical space in the truck.
Also, the SR and Flash have one 11kW charger, while the ER has two 9.6kW chargers.
So they are replacing 2 modules of the 9, number 8 and number 9 modules.
They are also replacing an HV junction box.
I wonder if the failed modules are 55 cell or 40 cell or one of each?
And what caused the junction box failure?
FYI:
Here is a video about HV junction boxes:
