Hello DIYDrones forum!
I’m posting requesting some help on this setup please. (And for reader interest).
Mission Planner gives the PreArm Warning: Battery Failsafe. And prevents arming.
Unless I disable the volt and current sensor, in which case the Batt Volts and Amps read 0.00.
But I must have the low-battery warning working correctly.
PixHawk Cube
ArduPilot Firmware build: V3.5.5 Octa Quad
Mission Planner 1.3.53 build 1.3.6652.13988
I have followed this guide, and entered the supplied calibration data from MAUCH.

Read the Mauch website guide

BOTH the current Cortex Drone systems here have this problem :(
Christian from Mauch has also sent me a few emails reinforcing the setup.
All the Sensor and Bec blue lights are on. Yellow on the GPS for Failsafe.
Here’s the setup in Mission Planner for Optional Hardware – Battery Monitor (1).
Mission Planner Parameters:
FS_BATT_VOLTAGE = 20
With a pack at 23.89V and the FS_BATT_VOLTAGE set to 20V, it is still in Low Battery Failsafe.
Same with another pack at 19.8V with Low Batt voltages set o 19.5V.
Reserved capacity entered is 10,000mAh.
Any suggestions please on what else to try?
