Battery Monitors (aka Power Monitors/Modules)

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

Up to 10 batteries/power monitors can be monitored. Each monitor has its own group of configuration parameters, designated by BATTx_ with x denoting each monitor in the system (first monitor “x” is null character, ie BATT_ prefix). In addition, a BATT_MONITOR “type” = SUM is available, that consolidates all following (higher numbered) battery monitors into a single report.

• Power Monitor Configuration

Power Monitors Connecting to AutoPilot Power Monitor Port

• Common Power Module
• AirbotPower Power Module
• CUAV HV PM
• Mauch Power Monitor
• SmartAP Power Distribution Board

CAN/DroneCAN Power Monitor

• CUAV CAN/DroneCAN PMU

Liquid Fuel Monitors

• Fuel Monitors

Power Monitors/Modules provide these benefits:

• Most provide a stable power supply to the autopilot, in addition to monitoring, and therefore 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 .
