Victron SmartShunt IP65 Battery Monitor (Bluetooth) - Waterproof 300A

In this review of the Victron SmartShunt IP65 battery monitor, the bottom line is simple: it is for people who want precise, app-driven battery insight and reliable integration with other system components. The SmartShunt's biggest selling point is its combination of accurate shunt-based measurement and wireless sharing through Bluetooth, which makes it useful for off-grid, marine, or vehicle electrics where monitoring and optimized charging are priorities. The unit is waterproof and compact, so it fits retrofit installs and provides instant data to a phone without complicated setup.

Key Features

• All-in-one waterproof design: IP65 protection keeps the monitor safe from dust and water spray, allowing installation in exposed or damp compartments.
• Bluetooth app display: Live battery data appears in the VictronConnect app for instant readout and alarm notifications on a smartphone.
• Precision shunt technology: The internal shunt provides accurate readings for state of charge, time remaining, amp hours and instantaneous current.
• Smart networking: Wirelessly shares battery sensor data with other Victron devices to improve charging efficiency and enable system-level features.
• Auxiliary connections: Built-in Aux cable can monitor a second battery, midpoint or accept an optional temperature sensor for better management.
• Versatile energy meter: Can function as a DC energy meter for broader system diagnostics and monitoring.

Who It's For

The SmartShunt is best for owners of small solar, marine, camper or vehicle battery systems who want accurate battery state information and easy integration with other Victron equipment. It suits DIY installers and professionals who need a retrofit-friendly, waterproof monitor that reports to a phone and to system controllers.

People who primarily need physical display-only readouts, extremely long-range wireless connectivity, or those who require a built-in remote display should look elsewhere, since this unit relies on the VictronConnect app and networked Victron devices for full functionality.

Pros & Cons

Pros

• Accurate shunt-based measurements give trustworthy state of charge and amp hour tracking.
• Waterproof IP65 housing and compact form make it easy to retrofit into tight or damp locations.
• Bluetooth integration and VictronConnect app provide instant readout and alarms on a smartphone.
• Aux output and wireless sharing let it work with other Victron devices to optimize charging.

Cons

• Bluetooth connectivity receives mixed feedback from users, so wireless performance can vary by environment.
• No built-in remote display, so a phone or additional Victron components are needed for off-board readout.
