This power module is designed to supply clean power and battery-voltage/current sensing to compatible APM flight controllers. Legacy copy contains conflicting input and output ratings, so confirm the label, connectors, calibration values and battery range of the supplied module before use.
An APM power module connects between a compatible flight battery and flight controller to provide regulated controller power plus voltage and current measurements. Correct data helps the autopilot estimate battery use and trigger configured battery warnings.
Key features and compatibility
Six-position flight-controller lead on common APM-style modules
Provides regulated power for compatible controller electronics
Senses main-battery voltage and current for supported autopilot software
Not intended to power propulsion motors or high-current servos
Connector type, maximum input and calibration values vary by module revision
Use this module only after matching the battery connector, cell count, flight-controller port and voltage/current limits. Calibration values should be set from the exact module documentation or verified with a trusted meter.
Before ordering: Previous copy listed different maximum cell counts and regulator-current values. Those conflicting figures are not repeated. Do not power the system until input/output polarity and connector pinout have been checked, and use a separate BEC where servos require it.
No. The main battery current passes through the module, but propulsion power is delivered to the ESCs; regulated output is for compatible controller electronics.
Can it power high-current servos?
No. Use a suitable separate BEC or power system for servos according to the aircraft design.
Why must calibration values be checked?
Different module revisions use different voltage and current scaling. Incorrect values produce inaccurate battery readings.
