Victron BMV-712 Black Smart Battery Monitor

The Victron BMV-712 Black Smart Battery Monitor is the gold standard for serious boaters and anglers who demand real-time visibility into their vessel's electrical system. Whether you're running a weekend fishing trip or extended cruising, this compact monitor sits at the heart of reliable battery management, protecting your investment and ensuring you never get caught with a dead house bank.

Built by Victron Energy—a name trusted across marine, RV, and off-grid industries—the BMV-712 delivers precision diagnostics that separate seasoned captains from those learning the hard way. This smart battery monitor uses a proven shunt-based system to measure voltage, current, and power consumption with high accuracy, eliminating guesswork about battery state-of-charge. The large backlit display clearly shows instantaneous draw in amps, remaining capacity in amp-hours, and time-to-empty calculations—critical data when you're offshore and need to ration power for navigation, communication, and lighting.

Anglers and cruisers benefit most from the BMV-712's Bluetooth connectivity, which pairs with the VictronConnect mobile app for wireless monitoring and firmware updates. Victron's patented algorithm learns your battery's characteristics over time, delivering increasingly accurate state-of-charge estimates. The compact design fits easily in any helm station, locker, or engine room without sacrificing functionality or durability.
