Ok thank you, that makes way more sense, with the pictures I’ve seen of Model 3 modules. Do you think a flex PCB could be used in a similar way for a smaller pack? The model 3 modules seem pretty dense, 200wh/kg +. Not including the mass of the outer protective casing as well as the penthouse that contains the bms controller, the charger, and the dc/dc converter.
Another question for Jehu’s PCB idea what possible problems do you see with his pack design. I already see issues with the use of normal battery holders in the first design, while the second design I think glues them together, and then welds/solders them to the board. Other than the low power output of the board of course.
