6 Voltage Monitoring
STEP1: Protection Switch
In order to prevent your multi-rotor from a crash or other harmful consequences caused by low battery
voltage, there are two levels of low voltage protection available to use. You can choose to use or not to use
them, however we strongly recommend using the protections available!
Notices:
Make sure the connection between VU and MC (V-SEN to X3) is correct; otherwise the low voltage
protection will not work properly.
Both levels of protection have LED warning as default. Both levels of protection will blink red
continuously.
Both level protections will only have the LED warning under Manual Mode, none in the automatic
actions.
Low voltage protections are NOT fun! You should land your multi-rotor ASAP in any level of
protection to prevent your multi-rotor from crash or other harmful consequences!
STEP2: Battery
Apply battery power the MC and connect the MC with the PC, current
battery voltage will be displayed in this column. If the battery voltage
displayed here is different from the voltage you measure from a voltmeter,
you have to calibrate it. Click the Calibration box, enter that voltage in the
