Victron SmartShunt 1000AMP/50MV Bluetooth Smart Battery Shunt

The Victron SmartShunt 1000AMP/50MV Bluetooth Smart Battery Shunt is the marine-grade battery monitor serious boaters and anglers trust to keep their power systems running safely. Whether you're managing dual battery banks on a saltwater center console, monitoring lithium banks on an offshore platform, or tracking auxiliary power on a liveaboard cruiser, this shunt delivers real-time data directly to your smartphone or display unit. Built by Victron Energy—the gold standard in marine electrical systems—it eliminates guesswork about charge state, consumption, and system health when you're miles from shore.

The 1000-amp capacity with 50-millivolt shunt design measures battery current with precision, allowing you to monitor amps drawn, amp-hours consumed, and state of charge with laboratory-grade accuracy. Bluetooth connectivity pairs seamlessly with the VictronConnect app or compatible marine displays, streaming battery diagnostics wirelessly so you can track voltage, current, and remaining capacity from the helm or anywhere aboard. The shunt's low-resistance construction minimizes voltage drop, protecting alternator performance and ensuring maximum charging efficiency—critical when regenerating batteries from solar, wind, or engine power in rough seas or extended offshore passages.

Professional installers and experienced cruisers rely on this shunt for lithium, AGM, and lead-acid battery systems rated up to 1000 amps continuous draw. It integrates seamlessly with Victron's MultiPlus inverter-chargers, MPPT solar controllers, and smart battery monitors, creating a complete energy management ecosystem. Compact dimensions make it easy to mount in engine rooms or battery boxes without taking up valuable space, while its robust marine-grade construction handles vibration, humidity, and temperature swings from the Gulf Stream to the Great Lakes. For anyone serious about battery health and system reliability, this shunt is non-negotiable.
