Hello MatejPacha
Since some time we are struggling to figure out why the BATS voltage sensed is always approximately 0.5V less than that given by DC Bus Voltage.
Is there any known reason for this?
Hello manishsangram,
Do you compare the ADC result to VSUP or VBAT with reverse battery protection?
Anyway, the specification says that the ratio between VSUP and ADC input is 9 with up to +-5% error + ADC conversion error.
