# 12S Power Module

The Auterion 12S Power Module can be used to power Skynode from 4S to 12S batteries (12V to 51V). The power module includes a 5.3V regulator with a maximum current rating of 8A and a 10V regulator with a maximum current rating of 2.7A. Furthermore the power module is used to measure battery voltage and current to the flight controller.

{% hint style="info" %}
The Power Module comes with a fan mounted on top.

The presence of the fan is fundamental to guarantee the performance described in the datasheet.
