Solo will Return Home automatically to prevent a crash once the battery drains down to approximately 10% (actual
percentage can vary slightly since Return Home trigger is based off voltage reading). After landing, turn off Solo
immediately; if the battery level reaches 0% at any time, irreversible damage can occur and the battery should be

6.2.6 Controller Battery Alerts
When the controller battery reaches 10% of its remaining charge, the controller will display an alert to notify you to
charge the controller at your next opportunity. At 5%, the controller will prompt you to end your flight and charge
the controller. If the controller battery reaches a critical level in flight, Solo will Return Home. The following displays
show (left to right) the 10%, 5%, and 0% alerts.
