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.
