PARAM_DEFINE_FLOAT() [1/3]

PARAM_DEFINE_FLOAT	(	BAT_CNT_V_VOLT	,
		-1.	0f
	)

Scaling from ADC counts to volt on the ADC input (battery voltage)

This is not the battery voltage, but the intermediate ADC voltage. A value of -1 signifies that the board defaults are used, which is highly recommended.

Battery Calibration 8

PARAM_DEFINE_FLOAT() [2/3]

PARAM_DEFINE_FLOAT	(	BAT_CNT_V_CURR	,
		-1.	0
	)

Scaling from ADC counts to volt on the ADC input (battery current)

This is not the battery current, but the intermediate ADC voltage. A value of -1 signifies that the board defaults are used, which is highly recommended.

PARAM_DEFINE_FLOAT() [3/3]

PARAM_DEFINE_FLOAT	(	BAT_V_OFFS_CURR	,
		0.	0
	)

Offset in volt as seen by the ADC input of the current sensor.

This offset will be subtracted before calculating the battery current based on the voltage.

PARAM_DEFINE_INT32() [1/2]

PARAM_DEFINE_INT32	(	BAT_SOURCE	,
		0
	)

Battery monitoring source.

This parameter controls the source of battery data. The value 'Power Module' means that measurements are expected to come from a power module. If the value is set to 'External' then the system expects to receive mavlink battery status messages.

PARAM_DEFINE_INT32() [2/2]

PARAM_DEFINE_INT32	(	BAT_ADC_CHANNEL	,
		-	1
	)

Battery ADC Channel.

This parameter specifies the ADC channel used to monitor voltage of main power battery. A value of -1 means to use the board default.
