This is a short clip of the Model 3 74kWh battery pack pulled from a salvage. It's not a complete teardown, as I'd like to keep this pack sealed for a future use. More info coming soon on this secret project, so please subscribe! I have not yet removed the cover exposing the modules, as this has already been covered by others. Under the black steel there are 4 long modules that run the full length of the casing that have a total of 96 bricks that contain 4416 total cells called “2170's” (21mm diameter, 70mm long). There are 46 of these cells in parallel in each brick, 2 of the long modules have 23 bricks in series, and the other 2 has 25 bricks in series for a total of 96 bricks in series. Let me know in the comments below what kind of videos you'd like to see on Tesla tech.

A short exploration of the bare drive unit removed from the subframe and with it's inverter removed. With inverter installed and full lubrication sump it was just under 200lbs/90kg. The inverter itself weighs only 8.5lbs/4kg. Halfshafts use the same spline and interface dimensions as S/X with the exception of the seal shoulder which is 40mm on 3 versus 44 on S/X. However, the seal OD (67mm) is the same, so you could swap in a seal from a S/X to use the heavier S/X halfshafts. Note that Tesla is using 4 of these exact same PMSRM (Permanent Magnet Switched Reluctance Motors) in the Tesla Semi. Though the gear reduction part is totally different. Same rear casting in fact, even with the vestigial rubber mount that is not being used in the Semi. ... https://www.youtube.com/watch?v=ANLPPKRwiyQ
