The Power Setup page is used to configure power sensing module parameters.
Enter data for your battery/power module from its data sheet: number of cells, full voltage per cell, empty voltage per cell. If provided, also enter voltage divider and amps-per-volt information.
QGroundControl can be used to calculate appropriate voltage divider and amps-per-volt values from measurements:
- Measure the voltage from the battery using a multimeter.
- Click Calculate next to the Voltage divider field. On the prompt that appears:
- Enter the measured voltage.
- Click Calculate to generate a new voltage-divider value.
- Click Close to save the value into the main form.
- Measure the current from the battery.
- Click Calculate next to the Amps per volt field. On the prompt that appears:
- Enter the measured current.
- Click Calculate to generate a new amps per volt value.
- Click Close to save the value into the main form.
QGC has a profile for the BlueRobotics Power Sense Module R2, which can be selected from the dropdown menu.
