xVictron SmartShunt 300A IP65 Battery Monitor
The Victron SmartShunt 300A IP65 is a standalone battery monitor designed for solar, off-grid, marine and vehicle installations where accurate state-of-charge tracking is essential. It connects via Bluetooth to the free VictronConnect app, removing the need for a separate display unit. The IP65 rating makes it suitable for installations in damp or dusty environments.
Key Features
- 300A continuous current rating, suitable for medium to large battery banks in 12V, 24V and 48V systems.
- IP65 ingress protection rating, providing resistance to dust and low-pressure water jets.
- Bluetooth built in, with full monitoring and configuration via the VictronConnect app on iOS and Android.
- Monitors state of charge, voltage, current, power, consumed amp-hours and time remaining.
- Compatible with all common battery chemistries including lead-acid, AGM, gel, lithium (LiFePO4) and lithium-ion.
- No display required: all data is read directly from a smartphone or tablet, reducing installation complexity.
- Supports VE.Direct connection for integration with Victron GX devices, MPPT controllers and other Victron equipment.
- Relay output available for high or low voltage alarms and other programmable triggers.
Product Overview
The SmartShunt functions as a precision current shunt combined with a battery monitor processor and Bluetooth transmitter in a single sealed unit. Unlike traditional shunt-based monitors, there is no separate monitor head or display panel to mount and wire. The shunt installs in the negative battery cable, and all configuration is handled through VictronConnect. This simplifies installation considerably, particularly in confined spaces such as motorhome battery compartments, boat bilges or off-grid cabinet enclosures.
The 300A rating covers the majority of residential off-grid and leisure battery installations. For systems drawing sustained high currents, the shunt handles continuous loads without thermal derating under normal conditions. The IP65 enclosure means the unit can be mounted in locations that would be unsuitable for standard electronics, including engine bays, outdoor enclosures and wet lockers. VE.Direct output allows the SmartShunt to feed data directly into a Victron Cerbo GX or Venus GX, making it a straightforward addition to any Victron-based monitoring setup.
Battery chemistry parameters are fully configurable in VictronConnect, including Peukert exponent, charge efficiency factor and tail current threshold. This level of configuration allows accurate state-of-charge readings across different battery types and ages, rather than relying on fixed default values.

Installation Notes
The SmartShunt is installed in the negative battery cable between the battery negative terminal and the system negative busbar. All negative loads and return cables must connect to the system side of the shunt, not directly to the battery, for accurate current measurement. Installation in battery systems above 48V or in grid-connected applications should be carried out by a qualified electrician. For lithium battery installations, verify that the battery management system is compatible with the shunt configuration before commissioning.
