A very well presented and detailed video of the teardown by Munro & Associates. 38 modules each with 4 groups of 3 cells in parallel wired in series (100 kWh) total.
Munro says the integrated cooling tray is a wonderful design! The EV9 also benefits from the extra 0.9 inch of ground clearance over the EV6 so there shouldn't be any issues with underbody damage write-offs.
