Victron BMV 712 battery monitor for two batteries with Bluetooth including shunt. Battery 1 volts, amps, amp-hours and Battery 2 volts.
The BMV-712 is the latest high precision battery monitor from Victron. The BMV-712 monitors voltage and current of a single battery bank and calculates power, state-of-charge and time-to-go. It also features an additional voltage input that can be used to measure an auxiliary or starter battery voltage, midpoint voltage or temperature with the optional temperature sensor. Data can be transferred to smartphones or computers with the inbuilt bluetooth module and external alarms can be triggered with the relay contact.
Installation is simply a case of connecting the supplied shunt in the negative battery cable, mounting the monitor in a 52mm diameter hole and connecting the wires. An optional wall enclosure is available if surface mounting is preferred.
