Balmar SmartShunt 350A - 12-48 VDC f/SG200 Display

The Balmar SmartShunt 350A - 12-48 VDC for SG200 Display is purpose-built for serious cruising sailors and power boaters who demand precision battery monitoring across multiple banks. Whether you're running house batteries, engine start, or auxiliary systems, this shunt integrates seamlessly with your existing Balmar SG200 display to deliver real-time voltage, current, and amp-hour data. It's the ideal upgrade for vessel operators who've outgrown single-bank monitoring and need to track independent battery performance across their entire electrical architecture.

This 350-amp shunt measures voltage and current draw with industry-leading accuracy, functioning across the full 12–48 VDC range to support everything from small sailboats to larger trawlers and expedition vessels. The shunt installs directly in-line with your battery bank's negative conductor, allowing the SG200 display (sold separately) to calculate state of charge, remaining capacity, and consumption patterns with precision. The included SmartLink Com Cable ensures plug-and-play compatibility, while the compact 6 x 4 x 9-inch footprint fits neatly in engine compartments or battery boxes without consuming valuable real estate. Weighing just 1.65 lbs, installation is straightforward for experienced electrical systems installers.

Best suited for cruising crews and commercial operators who run multiple battery systems, the Balmar SmartShunt 350A transforms battery management from guesswork into actionable intelligence. Pair it with the SG200 display or Bluetooth Gateway (both sold separately) to unlock full monitoring capabilities and make informed decisions about power consumption, charging cycles, and system health. Installation requires one gateway or display unit for programming, making it essential to have your display on hand before ordering this shunt. On extended passages and extended anchorages alike, knowing your true amp-hour reserves eliminates range anxiety and ensures you'll never find yourself without reserve power.
