Battery Failsafe not triggering

ArduCopter Copter 4.2

Hello,

I have an issue with battery failsafe not being triggered on my quad. The battery monitor and other parameters are set correctly. Once the voltage goes below the BATT_LOW_VOLT, mission planner voltage display turns Red, but does not switch to any of the failsafe modes even if the voltage drops 1V below the failsafe voltage.

ArduCopter V4.2.2:

BATT_LOW_VOLT,20
BATT_LOW_TIMER,10
BATT_LOW_MAH,0
BATT_FS_LOW_ACT,1
BATT_FS_CRT_ACT,0
MOT_BAT_VOLT_MAX,25.2
MOT_BAT_VOLT_MIN,18.0

Thanks

Use MissionPlanner initial parameters page to set all them correctly.
Provide the .bin log

I have used the initial parameters page to set the values. Attached is a log.

First of all, update to ArduCopter 4.2.3. BATT_LOW_TIMER will introduce a 10 second delay

I waited 2-3 min after the low voltage level is reached but the failsafe was not triggered. I will update to 4.2.3 and check.

Updated to 4.2.3 and tried different BATT_LOW_TIMER values but still it does not change the flight mode to LAND or RTL at failsafe.

Please post a .bin log of that
