Zero voltage (very probably) happened when cell # 3 lost itīs plus terminal due intense heat generated in internal Ohmic losses after a severe short circuit to ground.
God help us all...

I am saying it was severed by a metallic Lithium flare in the battery beneath.

If the system had not shut down (electrically, continuity interrupt), Thales has some "splainin" to do....

The cells are folded. There are no subcells. Neither is it necessary to achieve higher currents. The only relevant parameters are electrode chemistry and effective surface.
NO. Not in my understanding. In each battery are three separate electrodes, cells, consisting of a continuous "stack" ten meters long, folded. The length of all three is 30 meters, nominally...



Stand to be corrected....
