4 ADVANCED CONFIGURATIONS
This section will take you through the more advanced configuration and tuning
options for the vehicle.
4.1 Power Module
Common Parameters
BATT_ARM_VOLT: Required arming voltage.
Battery voltage level which is required to arm the aircraft. Set to 0 to allow arming at any voltage.
BATT_ARM_MAH: Required arming remaining capacity.
Battery capacity remaining which is required to arm the aircraft. Set to 0 to allow arming at any
capacity. Note that execept for smart batteries rebooting the vehicle will always reset the
remaining capacity estimate, which can lead to this check not providing sufficent protection, it is
recommended to always use this in conjunction with the BATT__ARM_VOLT parameter.
BATT_LOW_VOLT: Low battery voltage
Battery voltage that triggers a low battery failsafe. Set to 0 to disable. If the battery voltage drops
below this voltage continuously for more than the period specified by the BATT_LOW_TIMER
parameter, then the vehicle will perform the failsafe specified by the BATT_FS_LOW_ACT
parameter.
BATT_LOW_MAH: Low battery capacity
Battery capacity at which the low battery failsafe is triggered. Set to 0 to disable battery remaining
failsafe. If the battery capacity drops below this level the vehicle will perform the failsafe specified
by the BATT_FS_LOW_ACT parameter.
BATT_LOW_TIMER: Low voltage timeout
This is the timeout in seconds before a low voltage event will be triggered. For aircraft with low C
batteries, it may be necessary to raise this to cope with low voltage on long takeoffs. A value of
zero disables low voltage errors.
BATT_FS_LOW_ACT: Low battery failsafe action
What action the vehicle should perform if it hits a low battery failsafe.
