The 16V Li-Ion Battery used by Tesla

Check out the 16 Volt Li-Ion battery used in new Tesla Models S, 3, X, and Y. Learn how to determine if your Tesla has one. Learn the location, function, battery self-protection function, and precautions of the 16-volt system. Use my Referral code link to purchase a new Tesla https://ts.la/john304015 CORRECTIONS: 1. The 16V battery uses prismatic cells from CATL, not pouch cells. POST-VIDEO ADDITIONS: 1. The 16V negative terminal is NOT connected to the battery housing; it is isolated. 2. During an on-car 16V battery discharge experiment, the MOSFET transistors opened with the battery voltage at 13.8V, the State of Charge (SOC) was ~10%, and the car shut off. The discharge took 10 minutes. 3. With the MOSFETs open, a regular battery jumper box (12.6V) did not power up the system; however, the boost feature of the jumper box brought the voltage to 13.9V, and the Tesla immediately turned on. The 16V battery took another 30 minutes to fully recover from 10% SOC to 79% SOC.
