What are the power requirements of the 3p?

The 3p accepts power sources from 9-36V; we recommend a 3-6 cell battery.

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"
