What's to know about them? What's not to like...?
One button to toggle between the two displays. Just voltage for the start battery though.It seems the BM-1 can monitor Start Battery voltage in addition to House/Service Battery, if an appropriate cable is connected as per the installation instructions.
It is unclear from the FAQs how in practice the two blocks of information are accessed. It's likely 'something simple', but HOW...?
