The LXNAV SmartSHUNT 300A/50mV is a compact smart marine battery monitoring shunt designed to integrate seamlessly with your vessel’s NMEA2000 network. Supporting up to 300 A current measurement and 60 VDC systems, it provides accurate real‑time data including state of charge (SoC), consumed and remaining amp‑hours, battery voltage, current flow, and temperature. With built‑in Wi‑Fi for easy wireless setup and support for up to three battery banks, the SmartSHUNT 300A simplifies energy monitoring and keeps you informed wherever you sail.
The LXNAV SmartSHUNT 300A/50mV is a high‑precision battery monitoring solution designed for marine installations and NMEA2000‑based onboard systems. Acting as both a current shunt and battery monitor, it measures the true electrical current flowing in and out of your battery bank and translates this into clear, meaningful data — such as state of charge (SoC), consumed and remaining amp‑hours (Ah), real‑time current, voltage, plus temperature readings from up to three sensors. This information is shared over the NMEA2000 network, allowing connected instruments and chartplotters to display detailed energy status and performance.
Thanks to its built‑in Wi‑Fi connectivity, the SmartSHUNT 300A can be configured wirelessly via a smartphone or tablet — no special tools required. You can adjust settings like battery type (lead‑acid, AGM, GEL, LiFePO4), alarm thresholds, and temperature units to perfectly match your onboard setup. Once connected to an NMEA2000 network, all battery data is broadcasted to compatible displays, multifunction instruments, and chartplotters for seamless monitoring.
The SmartSHUNT 300A supports up to three separate battery banks and handles systems up to 60 VDC, making it ideal for sailboats, small powerboats, and yachts with modest battery configurations. Its marine‑grade design ensures reliable performance in harsh seafaring environments, giving you complete confidence in your vessel’s energy status during every voyage.
