Veratron 52MM (2-1/16") OceanLink Battery Current Gauge (-150/+150 AMPS) - Black Dial & Bezel

The Veratron 52MM OceanLink Battery Current Gauge is an essential monitoring tool for any serious vehicle build or marine electrical system. If you're running a high-output alternator, auxiliary battery bank, or custom power distribution setup, this analog gauge gives you real-time visibility into charging and discharge rates that digital displays often miss. Professional mechanics and automotive enthusiasts rely on current gauges to diagnose charging system faults, verify alternator output under load, and protect expensive electrical modifications from overcurrent damage.

Built by Veratron—a trusted name in marine and automotive instrumentation—this 52MM gauge features a ±150 ampere range, allowing you to monitor both charging (positive) and discharge (negative) current flow simultaneously. The black dial and bezel deliver excellent contrast and durability under harsh underhood or cabin conditions, while the OceanLink designation indicates compatibility with Veratron's standardized marine-grade electrical ecosystem. The compact 5-inch depth fits standard dash openings and pod mounts without requiring custom fabrication, and the robust construction handles vibration and temperature swings typical in modified vehicles.

This gauge is ideal for owners running auxiliary power systems, winches, inverters, or upgraded lighting who need to verify their alternator isn't being overdriven or to catch parasitic draws that drain batteries overnight. Installation requires a shunt or current-sense module in series with your main battery cable—a straightforward task for anyone comfortable with heavy-gauge wiring. Whether you're diagnosing a custom electrical build or simply validating that your charging system is performing as rated, the Veratron 52MM OceanLink Battery Current Gauge delivers the precision feedback that guesswork cannot.
