Actual battery capacity of the CT battery?

[Jedi2155]

Does anyone know what the actual CELL capacity of the Cybertruck is? I know they've mentioned 123 kWh, but was wondering since my TeslaFi reports at 136.17 kWh and it previously reported 128 kWh roughly.

After some googling, I found that the vehicle has 1344 cells, and each Cybercell V2 was ~95.03 Wh giving me a figure of 127.72 kWh raw capacity in the pack. Wondering if anyone has more accurate numbers.

This came about since I was wondering how efficient charging another vehicle is from the CT. Some initial numbers was my truck was at 40.52% when I started charging my Model Y, and after some time, it dropped to 26.82% when I got my first measurement (the Model Y stopped charging for about 40 minutes so this wasn't a perfect test though). In that 13.7% discharge (~16.851 kWh if I use 123 kWh as a base), the Y received 11.42 kWh DC (32A charger, added 15% over 1 hr 41 minutes).

Meaning overall efficiency was 11.42 / 16.85 = 67.7%. The Model Y measured 12.06 kWh input on the AC side. Although I think that 40 minutes of it not charging while CT was on really skewed the consumption a bit. Kinda surprising how inefficient it is.

There are four buckets of energy loss:
Keeping Cybertruck on
Cybertruck DC-AC conversion
Model Y AC-DC to pack conversion
Keeping Model Y on

Max transfered AC power (using bed outlet and mobile connector) is 7.68 kW so 95% AC-DC conversion, 400W truck, 300W Y (made up numbers), results in 7 kW into Y pack from 8.5kW pulled from truck or 83% overall efficency.
