About the Victron IP65 SmartShunt
Most batteries do not tell their current charge levels. With the SmartShunt all current flowing into and out of a battery bank is measured, and based on the measurements, state of charge is accurately calculated to provide an understandable percentage readout.
It shows important metrics like voltage, state of charge (SOC), remaining capacity and current draw. By adding the SmartShunt, battery banks without monitoring capabilities or a built-in BMS have a centralized solution for system management.
It is installed on the negative side of the bank between the negative battery terminal and the rest of the system. The two terminals on the shunt are labeled for “Battery Minus” and “System Minus” to indicate which side connects to the battery and which connects to the system. For additional installation information, see the full manual.
Why the IP65 Version
The IP65 rating means this SmartShunt is sealed against dust ingress and low-pressure water jets from any direction. Choose the IP65 version for installations where the shunt will be exposed to moisture, humidity, or dust, such as marine engine compartments, outdoor battery enclosures, under-hood vehicle installations, or any location that isn't a climate-controlled indoor space.
If your shunt will be mounted inside a dry, indoor electrical panel or enclosure, the indoor-rated SmartShunt is a more economical option with identical monitoring capabilities.
Bluetooth Functionality with VictronConnect
Victron’s VictronConnect app allows remote setting adjustment including alarms, battery parameters, auxiliary input type, and VE.Smart networking.
The status tab displays relevant information for the devices connected via auxiliary input in real time. This includes SOC, voltage, current, power draw, and time remaining for charging/discharging of the bank.
The history tab maintains lifetime battery statistics from the point of installation, and whenever a new record is reached, it overrides the previous data. It retains information even when the shunt has been interrupted or reset.
The trends tab shows up to two data points of choice on one graph from the previous 45 days. Choose from State of Charge (%), Starter Battery (V), Voltage (V), Current (A), Power (W) and Consumed Amp Hours (Ah).
An optional VE.Direct cable can connect the shunt to a GX device like the Cerbo GX for remote monitoring of real-time status in the VRM (Victron Remote Monitoring).
Auxiliary Input
The auxiliary input allows for one additional feature for monitoring. There are several options, but it can only do one of them at a time. Choose between midpoint monitoring, second battery voltage monitoring or temperature monitoring within the Victron Connect app.
Monitor the midpoint for series-connected batteries. Midpoint monitoring measures the voltage at the connection point between two sections of a series-connected battery string to compare the voltage of the top half of the string to the voltage of the bottom.
For systems where main batteries and starting batteries share a common negative, the SmartShunt monitors secondary battery voltage through the auxiliary input port. Monitoring secondary battery voltage is helpful in motorhomes and boats to ensure engine starting batteries remain sufficiently charged.
Sizing the Shunt
Choose between the 300A, 500A, 1000A, or 2000A shunt depending on the size of the battery bank it will be connected to. Victron recommends sizing for 125% of the maximum continuous current the system will carry.

Frequently Asked Questions
No. The SmartShunt connects directly to your phone or tablet via Bluetooth through the VictronConnect app. There is no physical display. If you want a wall-mounted display, Victron offers the BMV-712 which uses the same shunt with an included screen.
It installs on the negative side of your battery bank. One terminal connects to the battery negative, the other connects to your system negative. All negative current must pass through the shunt for accurate readings, so no other negative connections should bypass it.
Yes. The SmartShunt works with any battery chemistry including LiFePO4, lead-acid, AGM, and gel. Battery type is configured in the VictronConnect app so the SOC algorithm matches the charge profile of your chemistry.
Choose the IP65 version when the shunt will be exposed to moisture, humidity, or dust. Marine engine compartments, outdoor battery enclosures, under-hood vehicle installs, and any location that isn't climate-controlled are all good reasons to go IP65. If your shunt is inside a dry indoor panel, the indoor version is the same monitor at a lower price.
Victron recommends choosing a shunt rated for 125% of the maximum continuous current your system will carry. For example, a system pulling up to 400A continuous should use the 500A shunt.
Yes, through the auxiliary input. In motorhomes and boats where main and starting batteries share a common negative, the auxiliary input can monitor starter battery voltage so you always know if your engine battery is sufficiently charged. Note that the auxiliary input only supports one function at a time: second battery voltage, midpoint monitoring, or temperature sensing.
For local monitoring, Bluetooth is built in. To add the SmartShunt to a full Victron system with remote monitoring through the VRM portal, connect it to a GX device like the Cerbo GX using an optional VE.Direct cable.
Midpoint monitoring measures the voltage at the connection point between two halves of a series-connected battery string. It compares the top half voltage to the bottom half to detect imbalances early, which is especially useful in lead-acid series strings where one weak battery can degrade the entire bank.
