Blue Smart IP65 12/15 - Bluetooth Voltage higher than battery voltage

When connecting the charger to various batteries I tend to get a higher voltage displayed on the Victron App than measured across the battery terminals (using Smart BMV 712 + normal voltmeter). Example. Charger set on HIGH, App voltage says 14,7v but battery voltage says 14,6v. Could Temperature compensation cause unit to drop voltage but still display the expected voltage on the app?
