Tesla uses 3.7 V nominal, not 4.2 V. 110S Plaid shows as 410 V, 96S 3/Y show as 360V, etc. Your 48S would only be 180V per module.
Side note: I'm surprised to hear them say 4 modules, I thought the point of structural pack was to eliminate modules.
Aren't their LV batts LFP?
EPA filings show Cybertruck is 816V. So 220S, split into two 110S virtual packs for Supercharging on existing 400V equipment. Needless to say, 220S doesn't divide into 1366, 1376 or 13-anything-6.
EPA filings also show 150 Ah. That's 122.4 kW by simple multiplication. But simple multiplication gives us 105 kWh for Plaid (410 V * 256 Ah), 84 kWh for 3/Y-LR, etc. So CT usable may be closer to 115 kWh. 340 miles from 115 kWh is impressive efficiency. These filings are incomplete, but I'd be surprised to see the 816 V or 150 Ah change.
Something odd I noticed when looking up the Y-LR EPA filing. Y-P and Y-AWD are also in that same filing, but they only show one set of values for pack size -- 360 V and 235 Ah. That obviously doesn't apply to Y-AWD, which can't be 96S and certainly doesn't have anywhere near 84 kWh. I don't know if it's just an oversight or if they slipped that in there to hide 4680 data from the public. The actual test data, 92 kWh AC recharge for LR and 76.5 kWh for AWD, are consistent with commonly reported usable pack capacities of 81 kWh for LR and 67.5 kWh for the 4680 AWD.
67.5 kWh / 828 cells is 81.5 Wh per single 4680 cell. CT is supposed to have the upgraded 4680, of course, so maybe 88-90 Wh/cell. 220S6P would be 1320 cells and 116-119 kWh usable.
