The Victron BMV-712 Smart is a battery monitor that works with a 500A / 50mV shunt. It runs from a supply of 6.5 to 70 VDC and measures current to within 0.4 %. Bluetooth is built in, and the unit keeps 46 d of stored trend data. It has a bistable relay rated 60V / 1A and an aux input for a second battery voltage, the midpoint, or temperature. The enclosure is IP55 and marked not for outdoor use.
Our take
The IP55 enclosure is marked not for outdoor use, so the BMV-712 Smart belongs inside the cabin or a dry locker rather than on an open helm. Its 500A / 50mV shunt sets the current it measures, and the aux input can watch a second battery.
From our buying guide
An amp-hour figure needs its rate, since BCI says rated capacity is specified at a particular discharge rate, temperature and cutoff voltage.
Check before you buy:
- A voltage reading means little until the battery has rested, and each maker sets its own rest and table.
- Ignition protection on a charger or switch is the maker's statement, so read what it says and which standard it names.
