Veratron Ammeter Shunt -150/150AMP - 60mV Input - 12/24V

The Veratron Ammeter Shunt -150/150AMP - 60mV Input - 12/24V is an essential monitoring component for serious boaters and anglers who demand precision electrical diagnostics on the water. Whether you're running a saltwater fishing rig with multiple battery banks, a cruising trawler, or a high-performance center console, this ammeter shunt lets you track real-time current flow with accuracy that separates professional-grade installations from guesswork. When your electronics, charging systems, and auxiliary loads are pulling 150 amps or more, knowing exactly what your batteries are supplying—or consuming—can mean the difference between a full day on the water and an unexpected dead battery situation miles from shore.

This Veratron shunt operates on a precision-calibrated 60 millivolt output signal, translating high-amperage current draw into a low-voltage signal that your ammeter gauge or monitoring system can safely read without voltage drop affecting your boat's performance. The shunt's dual polarity design (-150/+150 amp range) captures both charging input and load discharge, giving you complete visibility into your electrical system's behavior in real time. Built to handle both 12-volt and 24-volt systems, this shunt accommodates everything from small bass boats with single 12V banks to larger cruising vessels running dual 24V systems or mixed configurations. The compact 2×2×7-inch form factor means it installs cleanly in tight engine compartments, bilge boxes, or battery switch enclosures without consuming precious space.

Experienced anglers and trawler captains rely on ammeter shunts like this Veratron unit to monitor battery health during long days offshore, troubleshoot electrical faults before they leave you stranded, and optimize charging cycles for lithium or AGM battery banks that demand precise voltage and current management. Installation requires direct connection between your main battery bus and ground, with shunt output wired to a Veratron or compatible analog ammeter gauge. At 0.55 lbs, this shunt is lightweight enough for portable installations yet rugged enough for the salt spray, vibration, and temperature swings of the marine environment. For anglers running tackle-heavy rigs with GPS, sonar, live wells, and auto-pilot systems, this ammeter shunt transforms guesswork into data-driven decisions about when to run engines, cycle auxiliary systems, and manage your power budget.
