Battery Failsafe
The Hercules drone includes several failsafe mechanisms designed to aid in vehicle recovery and prevent uncontrolled behavior in the event of a loss of control.
The Battery Failsafe specifically ensures a safe termination of the flight when the drone detects critically low battery levels.
By default, the Battery Failsafe is configured to trigger when the voltage drops to 43.5V, which corresponds to 3.625V per cell on a 12S battery.
Please pay special attention to the condition of your battery packs before any operation. For a 12S battery pack, the minimum recommended voltage is 3.5V per cell, which equals 42V for a fully balanced pack.
NEVER FLY BELLOW THAT VOLTAGE, Flying with a battery below 42V can result in the battery being unable to deliver the current required to keep the drone airborne, which may lead to a sudden loss of power and flight failure.
| WHEN IS IT ACTIVATED? | WHAT HAPPENS WHEN IT IS ACTIVATED? | CONTINGENCY MANEUVERS |
|---|---|---|
It is activated when the battery voltage remains below 43.5V for more than 10 seconds, which is equivalent to more or less 25% of the battery capacity | The message “Low Battery! ” appears on the screen and by default RTL flight mode is activated | When a battery failsafe occurs, the immediate action is to leave automatic control on the Drone and not interrupt the RTL maneuver. If the pilot interrupt the RTL maneuver, there is a risk that the battery voltage drops below a threshold in which the drone has not enough power to lift its weight and therefore suffer a hard landing |
