Current monitoring (Amperage) is supported by connecting a current meter to the appropriate current meter ADC input (See Board documentation).
When enabled Amps, mAh used and capacity remaining calculated and used by the telemetry and OLED display subsystems.
## Configuration
Enable current monitoring using the cli command
```
feature CURRENT_METER
```
Configure capacity using the `battery_capacity` setting, it takes a value in mAh.
The current meter may need to be configured so that the value read at the ADC input matches actual current draw. Just like you need a voltmeter to correctly calibrate your voltage reading you also need an ammeter to calibrate your current sensor.
Use the following settings to adjust calibrtion.
`current_meter_scale`
`current_meter_offset`
If you're using an OSD that expects the multiwii current meter output value then set `multiwii_current_meter_output` to `1`.
