Xantrex LinkLITE Battery Monitor

Unlock Precise Battery Insights for Your Power System

Imagine setting off on a weekend boating trip or an off-grid camping adventure, only to worry if your batteries will last the night. The LinkLITE battery monitor changes that by giving you real-time, fuel-gauge-like visibility into your battery bank's health. Unlike basic voltmeters that only show voltage—which can mislead under varying loads—this device tracks true state of charge (SOC), factoring in real-world variables like Peukert's effect, temperature shifts, and battery aging. It's your command center for 12V or 24V systems, handling everything from starter batteries to deep-cycle house banks in RVs, boats, or solar setups.

How Advanced Algorithms Deliver Reliable Readings

At its core, this monitor uses high-precision shunt-based measurement combined with sophisticated software to calculate remaining capacity accurately. A 500A shunt comes included, but its flexible shunt selection lets you scale up to 1,000A for high-demand applications like electric propulsion or large inverter loads. It automatically senses battery voltage types, displays charge/discharge currents, consumed amp-hours (Ah), and SOC percentage—all on a bright, backlit LCD that's readable even in low light or from angles.

Need oversight on multiple banks? A dedicated second input monitors voltage from a starter or auxiliary battery, ensuring your whole system stays balanced. Plus, customizable alarms trigger actions like firing up a generator at low SOC or protecting loads from overvoltage during fast charges.

Standout Features That Set It Apart

• Fuel-Gauge Precision: See voltage, current, Ah consumed/remaining, and SOC at a glance—no guesswork.
• Dual Battery Support: Track house and starter batteries simultaneously for comprehensive monitoring.
• Heavy-Duty Capability: Handles up to 1,000A with shunt options, ideal for demanding marine or RV power plants.
• Smart Alarms: Programmable relay automates generator starts or load shedding based on your thresholds.
• User-Friendly Design: Intuitive buttons, large backlit display, splash-proof panel, and quick-nut mounting for easy installs.
• Proven Reliability: CE and e-mark certified for marine and automotive standards, built to withstand vibrations and moisture.

Simple Installation for Lasting Performance

Getting up and running takes minutes: Mount the compact display with twist-on nuts, connect the shunt in-line on your battery negative, wire power and signal cables, and select your shunt size via the menu. Its auto-voltage sensing eliminates manual tweaks, while the intuitive interface lets you set alarms and efficiency factors tailored to your lead-acid, AGM, or lithium banks. Pro tip: Position the shunt near the battery to minimize cable voltage drop errors, and calibrate with a known charge for peak accuracy.

Once installed, it runs silently, updating every second without draining your battery—perfect for long voyages or remote solar monitoring.

Real-World Applications and Benefits

For boaters and sailors, it prevents deep discharges that shorten battery life during anchorages, extending runtime on fridges, lights, and nav gear. RVers love how it flags low SOC before dry camping turns sour, optimizing alternator charging cycles. In off-grid solar or cabin setups, pair it with controllers to automate loads and maximize panel efficiency. Owners report cutting battery replacements by 20-30% through informed usage, avoiding the "just one more hour" myth.

Beyond numbers, it brings peace of mind—knowing exactly when to recharge means fewer surprises and more time enjoying your setup.
