Small battery-16v

The Small Battery - 16V refers to the Lithium-Ion auxiliary battery used in newer Tesla models (notably Cybertruck and updated Model S/X) to replace the traditional 12V lead-acid battery. This 16V Li-Ion battery powers the vehicle's low-voltage electrical systems, including computers, lights, windows, and the infotainment system when the main high-voltage battery is off. It offers longer lifespan, reduced weight, and greater efficiency compared to 12V batteries, and is a critical component for overall vehicle operation and reliability.
