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 Monitors Connecting to AutoPilot Power Monitor Port¶
CAN/DroneCAN Power Monitor¶
Liquid 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 .
