Just saw the Cybertruck breakdown, Batteries look to be 192s7p
Nerdy post, Cybertruck battery pack alignment. . .
Cybertruck battery modules have 4680 cells, aligned with 7-pack of cells in parallel and 192 packs in series. This gives 1344 total cells. (shorthand 192s7p)

The thing I don't like, they have a fuse on each battery cell that cannot be replaced, with only 7 batteries in parallel, if 1 out of the 1344 batteries blow a fuse, you have limited your total power output by 15%, plus put a lot of strain on the remaining 6 battery cells in the set of batteries in parallel.


Things are very different from the current Model S that uses much smaller batteries, they have lighter battery pack with 100 KWH using 7104 total cells. They are 96s74p. This setup needed a lot more fuses (which are really cheap and simple to do) . But if you blow 1 fuse, the other 73 batteries in parallel would have to share the dead load, which is not much.


I have no idea how this will play out in the long term, but I am curious if this will affect long term battery mileage. . . Because fuses blow, and even if Cybertruck blows 5% as many fuses, each blown fuse will have a much larger impact.
