Victron Energy Smart Battery Shunt 6.5–70V 300A — Bluetooth high-accuracy battery monitor

The Victron Energy Smart Battery Shunt is a compact, high-accuracy battery monitor and shunt that measures voltage, current, state of charge and more, with Bluetooth and VE.Smart networking for remote and system-wide monitoring.

Designed for mobile, marine, RV, camper and off-grid battery systems, the Smart Battery Shunt combines precision shunt technology with wireless convenience. It delivers detailed battery metrics to the VictronConnect app and can share data with other Victron devices or a VRM portal for remote oversight. Lightweight and unobtrusive, it replaces bulky analog meters with digital, app-driven insights while providing auxiliary connections for expanded monitoring options.

How does the Smart Battery Shunt show real-time battery health?

The unit continuously measures current, voltage and accumulated amp-hours via its precision shunt element and reports analytics to your phone and system controllers. You get instant feedback on State of Charge, time remaining and historical extremes so you can plan usage or charging more intelligently.

• Current, voltage and amp-hour tracking updated live
• Calculated State of Charge and Time Remaining
• Records deepest discharge and highest/lowest recorded voltages
• Alarm notifications pushed in-app for urgent events

What connectivity and integrations are available?

The Smart Shunt connects wirelessly to the VictronConnect app via Bluetooth for local monitoring and configuration. It also supports VE.Smart Networking to share sensor data with other Victron components and can link to a communication center for VRM remote management and DVCC system-wide battery control.

• Bluetooth connection for smartphone setup and readout
• VE.Smart Networking to optimize charging across devices
• Optional integration with VRM for cloud monitoring
• Compatible with DVCC for coordinated charge/discharge control

What additional monitoring or expansion options exist?

An auxiliary port expands functionality: use it for a second monitoring channel, midpoint sensing for multi-bank setups, or attach an optional temperature sensor. The same hardware can function as a general-purpose DC energy meter, making it a flexible tool for modern battery installations.

• Aux cable for second battery monitor or midpoint sensing
• Optional temperature sensor input to refine battery calculations
• Operates as a DC energy meter for load and generation tracking
• Wide operating voltage range for 12V–48V systems (6.5V–70V input range)

How accurate and durable is the measurement system?

The Smart Shunt uses a precision current shunt and calibrated electronics to deliver reliable results for amp-hours, charge cycles and voltage extremes. It’s built for installation inside battery compartments or electrical enclosures and engineered to work with high-current systems up to 300A continuous.

• High-precision shunt technology for dependable readings
• Rated for continuous 300A current measurement
• Wide input voltage tolerance for varied battery chemistries
• Robust construction suitable for mobile and marine environments

Who is this for: The Victron Energy Smart Battery Shunt is intended for anyone who needs accurate, app-driven battery intelligence—RVers, boat owners, off-grid homeowners, electricians building hybrid systems, and integrators who require networked battery data. It’s especially useful when space is limited but detailed battery diagnostics and integration with other Victron components are important.
