Victron Energy SmartShunt Battery Monitor 6.5–70V, 1000A — Bluetooth real-time SOC and precision shunt readings

The Victron Energy SmartShunt is a compact, high-precision Bluetooth battery monitor that tracks voltage, current, state of charge and more for 6.5–70V systems up to 1000A.

Whether installed in boats, campervans, off-grid cabins, or backup power setups, the SmartShunt replaces bulky gauge clusters with a single in-line shunt and wireless telemetry. It measures key battery parameters with shunt-level accuracy and streams live data to the VictronConnect app so you can view status, receive alerts, and integrate with other Victron components for smarter charging and system control.

How does the SmartShunt show battery condition on my phone?

The SmartShunt broadcasts detailed battery information over Bluetooth directly to the VictronConnect app, giving instant access to voltage, current, amp-hours used, and an estimated state of charge. Real-time alarms notify you of out-of-range conditions so you can act quickly.

• Live data: voltage, current, amp-hours, and time remaining
• State of charge percentage and charge cycle count
• Push alerts for low battery, high voltage, or abnormal current
• Historic min/max values for voltage and deepest discharge

What system integrations can I set up with the SmartShunt?

The SmartShunt can wirelessly share measurements with other Victron devices using VE.Smart Networking and can connect to a communication center for remote monitoring and advanced control. This enables coordinated charging strategies across inverters, chargers, and solar controllers without extra sensors.

• VE.Smart Networking for device-to-device data sharing
• Compatible with VRM for remote system monitoring over the internet
• Enables DVCC for system-wide battery (dis)charging control
• Aux input supports midpoint sensing or optional temperature probe

How accurate and reliable are the measurements?

Measurements are derived from precision shunt technology, providing highly accurate current and amp-hour calculations used to estimate remaining capacity and time-to-empty. The unit logs key extremes and cycle counts to help track battery health over time.

• Precision shunt for consistent current and amp-hour readings
• Records highest/lowest voltages and deepest discharges
• Maintains cycle count and cumulative amp-hours
• Works across 6.5–70V systems and up to 1000 amps

What mounting and auxiliary options are available?

The SmartShunt is compact and installs in-line with the negative battery connection, making it straightforward to retrofit into existing systems. An auxiliary cable accepts additional sensors or a second shunt input for midpoint monitoring or multi-bank setups.

• Simple retro-fit installation into negative battery line
• Aux cable for temperature sensor or second monitor connection
• Functions as a DC energy meter for system consumption tracking
• Robust design suitable for mobile and marine environments

Who is this for? Installers, vanlifers, boat owners, and small off-grid system builders who want precise battery analytics without a bulky display will find the Victron Energy SmartShunt ideal. It’s especially useful for anyone who needs accurate amp-hour accounting, remote visibility via VictronConnect or VRM, and seamless integration into a Victron-managed charging ecosystem.
