Battery Monitors (aka Power Monitors/Modules)


The links below have information about the most commonly used power monitors/modules


In firmware versions 4.0 and later, up to 10 batteries can be monitored. In addition, a new battery “type” = SUM, that consolidates all following (higher numbered) battery monitors into a single report, has been added to each monitor.

Power modules provide these benefits:

  • Provides a stable power supply to the autopilot and reduces the chance of a brown-out
  • Allows real-time monitoring of the battery’s voltage and current and triggering a low battery failsafe
  • Allows compensating for the interference on the compass from the motors using the COMPASS_MOT_x and COMPASS_PMOT_x parameters, see Advanced Compass Setup .
