The robot starts and stops the operations automatically based on current batteries charge level.
The FD20 has been equipped with two different types of batteries:
- Until model year 2020, they have been equipped with 4 pcs. AGM batteries
- From model year 2021, they have been equipped with 2 pcs. Lithium batteries
To understand when the robot stop, shutoff or resume autonomously its operations, there are 4 battery levels to consider:
- FULL CHARGE LEVEL (28V Lithium, 26V AGM) - the battery of the robot has reached its maximum capacity and cannot absorb further energy
- IDLE LEVEL (24V Lithium, 22.5V AGM) - 10 minutes after reaching it, the robot stops the autonomous operation, but the basic components are still turned on. This allow the robot to resume autonomously the operations in the morning.
- SHUTOFF LEVEL (23V Lithium, 21V AGM) - the robot shuts off completely, and must be restarted manually in the field, once the batteries are charged again. This is a safety measure to extend the life of the battery pack
- RESUMING LEVEL (26V Lithium, 24.5V AGM) - upon reaching this voltage, the FD20 will start again the autonomous operations.
The only exception to this is if the batteries reached the shutoff value (23V). In this case the robot must be turned on manually in the field.
TIPS AND TRICKS 😁👇
It is always recommended to restart the operations only when the batteries are AT LEAST 26V. This will both extend their operative life, but also make sure the robot has enough reserve of energy to work while it's charging with the sun.
TIPS AND TRICKS 🤓👍
Make sure to keep the solar panels of your FD20 well clean! Especially in the beginning of the season this practice can extend the runtime of your robot.
