This power module for APM 2.5, 2.6, 2.8 and Pixhawk flight controllers is available with a T-plug (Deans) or an XT60 connector. The listing describes a compact module that provides clean, regulated 5.3V power from a LiPo battery of up to 6S (28V).
It also provides real-time battery voltage and current consumption data through a 6-pin DF13 cable, so the flight controller can monitor the battery.
The module is fully assembled with the battery connectors attached, and it suits RC drones, multirotors and fixed-wing aircraft.
Two connector variants: T-plug (Deans) or XT60 battery connector.
Up to 6S: 28V maximum input voltage.
90A current sensing: maximum current sensing range.
5.3V regulated BEC: clean power for the flight controller.
5V ADC scaled sensing: voltage and current measurement.
6-position DF13 cable: plugs into the power port.
Fully assembled: connectors already attached.
A power module sits between the flight battery and the rest of the aircraft. It does two jobs: a built-in regulator (a BEC) converts the battery voltage to a clean 5V-class supply for the flight controller, and a current and voltage sensor reports how much power the aircraft is drawing. The flight controller uses the readings for battery-level warnings, failsafe decisions and flight logs.
For the readings to be trustworthy, the flight controller's battery monitor needs to be set up for the module. Enter the correct voltage and current scaling values, and compare the reported voltage with a multimeter at the battery to calibrate it. A wrong scale factor can make a battery look fuller or emptier than it really is.
Do not use the regulator to power servos or other high-current devices unless the manual says it can, because a heavy load can pull the supply down and reset the flight controller. Keep the module cool and make sure that the solder joints and connectors are secure, because this part carries the full current of the aircraft.

The specification list gives a maximum BEC output current of 3A for the T-plug version and 2.25A for the XT60 version, a maximum input voltage of 28V (6S LiPo), a maximum current sensing of 90A and a 5.3V regulated switching output. The flight controller connector is a 6-position DF13.
The listing notes that the BEC is meant for the flight controller, and that the servo power rail is excluded, so power servos separately.
