The power budget is impressive to impossible. They show 4 cells of unknown specifications. Let's suppose they're 32650s, the largest listed at https://en.wiki

The power budget is impressive to impossible. They show 4 cells of unknown specifications. Let's suppose they're 32650s, the largest listed at https://en.wikipedia.org/wiki/List_of_battery_sizes#List_of_Li-ion_sizes https://en.wikipedia.org/wiki/List_of_battery_sizes#List_of_... so you get 4 x 3.7V x 6000mAh/year ~= 10milliwatt average power consumption. (or 2.7mA @ 3.7V) Curiously, in the only datasheet I found for the IMX323 sensor, sony hasn't yet characterized the current or power requirements of the sensor -- but it's a datasheet hosted by a third party so who knows. http://support.hkvstar.com/file/IMX323LQ-C.pdf http://support.hkvstar.com/file/IMX323LQ-C.pdf
