OnlineHelp: Modules Battery
Most boards CANNOT tolerate more than 3.3V brought into them. This apply both to the Current and VOLTAGE Pins! So do not connect directly your lipo pack to one of the ADC pin unless the board is specifically designed for this purpose. If the sensor does provide more voltage, you can make a simple voltage divider with two resistors. Flight controllers with built-in sensors do not have this issue obviously.
Some boards require you to enable the ADC pins. E.g. Sparky you must select an OutPort in the hardware page with ADC functionality. On Quanton select Receiver input "PPM and ADC" for example.
- Enable the Battery module using the Modules - Enable page.
- Reboot the board
- Go to the battery tab within the modules page
- Assing whichever pins are used for voltage and current
- Update the scales from the table below. Note the offset factors will probably be incorrect and need to be adjusted for your particular sensor and board.
| Hardware | Voltage Pin | Current Pin | Voltage Factor mV/Volt | Current Factor mV/Amp |
|---|---|---|---|---|
| Seppuku | ADCO | ADC1 | todo | (*) |
| PikoBLX | ADC1 | n.a | 90,909 | n.a |
| OmnibusF3Clone | ADC1 | ADCO | 90,909 | todo |
| OmnibusF4Clone | ADC1 | ADCO | 90,909 | todo |
| ColibriPowerCube | ADC1 | ADCO | 90,909 | todo |
(*) this board requires a separate sensor, so user should use the Current Factor of the sensor installed
| Sensor | Voltage Factor mV/Volt | Voltage Offset V | Current Factor mV/Amp | Current Offset |
|---|---|---|---|---|
| AttoPilot 180A | 63.69 | -0,15 | 18.30 | -0,6 |
| AttoPilot 90A | 63.69 | -0,15 | 36.60 | -0,6 |
| RCTimer 90 A | 63.69 | -0,15 | 36.60 | -0,6 |
Some ESCs do have built in sensor that can just behave as a separate sensor.
