Sandy Munro has released another video that should provide some clarity on his view of the Tesla 4680 battery pack. In a previous video, he revealed that he believes the new pack will contain 960 cells, which will be located in four modules. Inside each module, there will be a connection that basically mimics the kind of connection we see with flashlight batteries. In his new video, he tries to better explain exactly what he meant.
Earlier, Munro conditionally divided the layout of Tesla's battery pack into four parts using black duct tape. Now he explained that, in reality, the battery will not be divided into four modules, but that he explained it this way for clarity. The battery cells will be placed parallel to each other in several rows.

The central part (where the red button is) is the positive part, the cathode side. The anode side (where the black button is) is the negative side.
One end of a conventional flashlight battery has a ledge for the positive side and a flat end for the negative. If we want to make the flashlight work, then we need to put one battery on top of the other so that the positive and negative ends of the battery touch each other. After that, when turned on, the flashlight will work.
Munro thinks this is exactly what Tesla will do in its battery packs. The connections will be laid in such a way that each module will work as a single battery. Further, the connection will be laid between the four batteries (modules) such that ultimately they work on the same principle as the batteries in the flashlight.

Each battery cell will sit on the Battery Module Coolant Manifold, which will conduct heat away from it in an efficient way.
Tesla unveiled its new 4680 cell architecture, which is significantly larger than the current 2,170 cells used in Tesla Model 3 and Model Y. Larger cells will mean more weight and heat dissipation, which Tesla will successfully solve with the tabless architecture. As a result, the company achieves a form factor with a 6X increase in power that allows it to increase range by 16% while reducing costs in $/kWh by 14%.
