## **X55 Serial Number**

The X55 manufacturer serial number is located beside the “FC Access” Panel.

## **Recommended land voltage**

We recommend landing the X55 at 44V, to give the pilot plenty of headroom in case of emergency, and also for better battery health.

{% hint style="danger" %}
This landing voltage is based on the recommended X55 batteries (2x Tattu 12S 16Ah batteries), and the landing voltage might vary with other types of batteries.
