Has anyone opened a 60kwh pack? My research shows the 60kwh pack has 14 modules. But that would be 73kwh if they are the same modules as the 85. So, either... 1.) there are fewer cells (empty places) in the modules 2.) the 60kwh car uses completely different cells, e.g. 2.6Ah cells. 3.) The 60kwh pack is way overbuilt #2 would explain the higher efficiency. Lower capacity cell would likely have lower internal resistance, thus more efficient under load. #3 is not possible, based on reported voltages when dead/charged. It's either 1 or 2. I'm leaning to 2. since 2.6ah cells would likely be considerably cheaper. The NHTSA photos of a 60kwh pack appear to show "empty spots" for cells, however, they are only missing from some modules. This wouldnt work. You'd need to remove the same # of cells from each parallel back or the back would be horribly imbalanced. I am guessing the missing cells in those pictures are sharpy marks, black tape, or since its a non functional car they put in some wonky modules.
