How do I power my 2p sensor?

A rough estimate to calculate the sensor's "on-time" is to calculate a battery's total capacity and then divide by the sensor's power draw of 11W. Peak draw is 3A upon sensor startup.

For example:

14.8V x 1300mAh = 19240 mW or about 19.2WH 19.2WH / 11W = 1.75 hours of 3p "on-time"
