Victron SmartShunt IP65: Precision Bluetooth Battery Monitoring for Demanding Off-Grid and Mobile Systems

Advanced Battery Management Without a Fixed Display

The Victron SmartShunt IP65 redefines battery monitoring by eliminating the traditional wired display and instead using your smartphone or tablet as the interface. This approach reduces installation complexity and cost while delivering the same high-accuracy measurements expected from Victron. Through the VictronConnect app, you gain real-time insight into battery voltage, current, state of charge, and time remaining, along with 46 days of logged trends to analyse usage patterns and system health.

Designed for 12V, 24V, and 48V systems with a wide 6.5–70 VDC supply range, the SmartShunt IP65 suits lithium, AGM, gel, and flooded lead-acid batteries. Its IP65-rated enclosure protects against dust and water jets, making it a reliable choice for marine, 4WD, caravan, and off-grid solar installations where moisture and vibration are constant challenges.

Why Accurate Current Measurement Matters

Generic battery monitors often rely on voltage alone, which can be misleading under load or during charging. The SmartShunt IP65 uses a precision shunt resistor to measure current with ±0.4% accuracy and a resolution of 0.01 A, ensuring your state-of-charge reading reflects true energy flow. This eliminates guesswork, prevents unexpected battery depletion, and helps you size your system correctly—whether you're running a fridge in a camper trailer or managing a large lithium bank in a remote solar installation.

Built for Harsh Australian Conditions

From the corrosive salt air of coastal cruising to the red dust of outback tracks, the SmartShunt IP65 is engineered to endure. The sealed housing, heavy-duty M10 (approx. 3/8") brass connection bolts, and wide operating temperature range of -40°C to +50°C ensure consistent performance. The integrated Bluetooth module maintains a reliable 10–15 metre range, and for installations where metal structures limit signal, an optional VE.Direct Bluetooth Dongle can be added.

Key Features

• Integrated Bluetooth – Wireless monitoring and configuration via the free VictronConnect app on iOS and Android
• IP65 Water and Dust Protection – Suitable for engine rooms, bilges, and exposed outdoor locations
• Auxiliary Input – Monitor a second battery voltage, battery temperature (with optional sensor), or midpoint deviation for battery bank health
• VE.Direct Port – Wired connection to GX devices (e.g., Cerbo GX) for internet-based monitoring and system integration
• 46-Day Trend Storage – Review historical voltage, current, and state-of-charge data to optimise energy usage
• Ultra-Low Power Draw – Consumes less than 1 mA, preserving battery capacity during storage
• Wide Voltage Compatibility – Operates from 6.5 to 70 VDC, covering 12V, 24V, and 48V battery systems
• High-Resolution Measurements – 0.01 A and 0.01 V resolution with ±0.4% current accuracy for precise energy management

Simplified Installation and Setup

The SmartShunt IP65 combines the shunt and monitoring electronics into a single compact unit, reducing wiring and potential failure points. Two 1.5-metre fused cables are included for the positive supply and auxiliary input, while the VE.Direct cable is pre-fitted for connection to a GX device. A QR code on the housing provides instant access to manuals and pairing instructions, and the VictronConnect app guides you through battery configuration in minutes.

Applications

This battery monitor is ideal for anyone who needs accurate, real-time battery data without a dedicated display:

• Marine and Boating – Track house and starter batteries, with optional temperature sensing for optimal charging in engine compartments
• 4WD and Caravan – Monitor auxiliary batteries running fridges, lights, and inverters, and avoid deep discharges that shorten battery life
• Off-Grid Solar – Integrate with Victron GX devices for remote monitoring of cabins, tiny homes, and remote telecommunications sites
• Commercial and Industrial – Manage backup battery banks for security, monitoring, and critical loads with trend logging for maintenance planning

SmartShunt IP65 vs. Traditional BMV Monitors

While the SmartShunt IP65 shares the same measurement core as the BMV-712, it omits the physical display, programmable relay, and audible alarm. Instead, all alerts and data are accessed through the VictronConnect app or a connected GX device. This makes the SmartShunt IP65 a cost-effective, space-saving solution for systems where a dedicated display is unnecessary, and the IP65 rating adds environmental resilience not found in standard BMV models.

For installations requiring automated load disconnect or generator start, a BMV with relay may be more suitable. However, for pure monitoring with maximum durability, the SmartShunt IP65 excels.
