„10" = Behaviour in case of undervoltage
Select how the flight controller is to react if undervoltage recognition is activated (see menu item „3").
Select „Power reduction" to reduce motor power when the undervoltage limit is reached. Select „Motor deactivation"
to deactivate the motor completely when the undervoltage limit is reached.
With the setting „Power reduction", the motor continues to run and discharge the rechargeable battery. To
avoid harmful deep discharge of the battery at the setting „Power reduction", the motor should be switched
off as quickly as possible and landing initiated.
We also recommend setting the undervoltage recognition for LiPo batteries to 3.2 V/cell in the „Power
reduction" setting.
