Mauch Power-Cube Dual Battery Kit
This complete kit provides all the components and cables necessary to power your flight controller and other onboard equipment.
- 2x Sensor boards: 50A, 100A, or 200A current sensors
- 1x Power supply: Power-Cube with 1, 2, 3, or 4 outputs
- 1x Sensor Hub X2
To power the Pixhawk 1, make sure to select the additional flight controller cable.
The Power-Cube series was created to take care of even the most demanding applications and is capable of powering virtually all types of equipment.
The design is based on the LM5116 from Texas Instruments; without compromise and with better component selection (oversized FETs, SPEC capacitors from Panasonic…).
- Rated for continuous current of 10A with max. current at 15A (limit 20A).
- Input reverse polarity protection.
- Cooling fan.
- Status LED for each power output.

S. 040: sensor cable / Molex CLIK-Mate 1.25mm 4p
This cable connects the Power-Cube to either a Sensor Board or the Sensor Hub X2. This cable comes with all Power-Cubes.
1. Power cable for Pixhawk 2.1 / Molex CLIK-Mate 2.0mm 6p
This cable connects the output 1 of the Power-Cube to the Power 1 input of the Pixhawk 2.1. This cable comes with all Power-Cubes.
2. Backup power cable for Pixhawk 2.1 / Molex CLIK-Mate 2.0mm 6p 1x JR servo
This cable connects the output 2 of the Power-Cube to the Power 2 input of the Pixhawk 2.1. The JR servo connector can be connected to the servo rail of a Pixhawk 2.1, to power up opto ESC or any other equipment. Do not use to power up digital servos or any other high current consumption equipment. This cable comes with all Power-Cubes 2, 3, and 4.
3. 5.0V output cable / Molex CLIK-Mate 2.0mm 6p 3x JR servo
Connect to any 5V equipment.
For example connect 2x JR to the servo rail to power up digital servos and the 3rd for LEDs. This cable comes with all Power-Cubes 4.
4. 12.0V output cable / Molex CLIK-Mate 2.0mm 6p 3x JR servo
Connect to any 12.0V equipment. This cable comes with all Power-Cubes 3 and 4.
Calibration Values Provided and Ready to Input into Mission Planner
Having accurate calibration values configured in ArduPilot is of paramount importance for the proper computation of battery consumption, as well as the reliability of alerts and failsafes which are critical safety features. Each Sensor Board is individually tested with a flight controller and the calibration values of the specific Sensor Board are determined. The highly accurate calibration values of each Sensor Board is provided in a format that can be directly entered into ArduPilot. Not everybody is willing to go through the steps of properly calibrating their power module. The Sensor Boards remove the need for users to painstakingly perform the calibration steps.
1. In Mission Planner, under INITIAL SETUP >> Optional Hardware >> Battery Monitor, set the “Sensor” to “Other”.
2. Enter the “Voltage divider” value provided with your Sensor Board, then click out of the field to save the value. The calculated “Battery voltage” value should be within a few millivolts of the actual battery voltage.
3. Enter the “Amperes per volt” value provided with your Sensor Board, then click out of the field to save the value.
Advantages compared to other power modules
- The current measurements use the full range of analog input voltage of the flight controller from 0.0V (corresponding to 0A) until 3.3V (corresponding to 50A, 100A, or 200A, respectively), so there is no need to adjust the parameter “BATT_AMP_OFFSET.”
- The original 3DR power module and most Atto boards experience voltage drops during hover (0.5-1.5V) caused by the resistance of the connectors and wires. In the Sensor Boards, the voltage drop error is minimized as only the resistance of the positive battery wire is measured. Additionally, the power supply for the BEC is separated and can be connected as close as possible to the battery. This results in more stable voltage/current measurements, accurate to /- 0.5%.
- Furthermore, the voltage sensor has a filter which reduces the risk of false RTL trigger, which might otherwise happen in very windy conditions due to sudden motor speed up.
- The maximum output voltage of the sensor board is limited to 3.3V, so there’s no risk of damaging the analog inputs on the flight controller.
Each Sensor Board is thoroughly bench tested using MAUCH’s rigorous process. The final QC is a setup with a flight controller (Pixhawk 2.1) and connected to Mission Planner to check the current and voltage calibration values.
Do you know any other manufacturer who uses an actual flight controller to test the calibration values of power modules?
Sensor Board Voltage Selection:
If using a battery up to 7S, you can close the solder bridge on the Sensor Board to achieve more precise measurements at those lower voltages. In this case, use a voltage divider value of 10.0 (the measurement will be fairly accurate) or perform the voltage calibration procedure for ArduPilot.
If using a battery of 8S or more, or if you decide not to close the solder bridge, use the pre-calibrated voltage divider value provided with your sensor (around 27).
Use double side tape or screw onto the frame by removing the M3 screws and drilling holes into the frame. Reinstall the screws through the frame. The original screws will be too short, so please replace them with longer ones according to the thickness of your frame.
