Wow - Peter really goes into depth on the battery. There's been discussions in other threads about 220 cells X 4.2 V per cell = 924 V. He covers that. He also confirms that the T and P will have 756 V systems. And if I understood him correctly, higher voltage was for heat reduction, not for faster charging. Overall, a good video to watch to understand batteries, the Lucid design, and be competent in discussions with other people.
