Tesla Battery (via YT/Model 3 Owners Club)
Via a relatively new You Tuber who goes by the handle of "Tesla Model 3 Owners Club," we get this highly informative video that takes us inside the Tesla Model S battery pack. The individual cells are examined in details, as well as the cooling system that's employed by Tesla.
The latter half of the video focuses on the Tesla gigafactory.
"Everything you wanted to know about the innards of a Tesla battery pack. 18650 cells, pouches, the Gigafactory and my best Elon Musk impression."
