Just released is a detailed, but not overly technical, video about the 16v aux lithium battery for those who have it in newer Teslas.
The video has timestamps for easy access to pertinent information. Of most interest might be:
1:50 The jump-start terminals of the Model 3
2:18 Owner's manual jump-start cautions
4:18 Mislabeled 16V batteries
5:29 MUST SEE: Differences between 16V Li-Ion abs 12V Lead Acid battery
7:45 MUST SEE: The push-fit battery 16V electrical connector
8:55 The jump-start terminals of the Model Y
9:28 The Internal self-protection mode of the 16V battery
11:10 MUST SEE: Conditions for the MOSFET to open in protection mode
15:17 What alert is displayed with a bad 16V battery?
15:42 How to recover a 16V battery with an open MOSFET
16:08 The owner's manual method of recovery
17:47 The service manual method of recovery
18:15 Disconnecting the 16V battery
21:12 The Toolbox 3 and service mode methods of recovery
My model 3 is of the legacy 12v system, I found this video quite fascinating and informative.
