Victron SmartShunt 300A 50mV Bluetooth Battery Monitor

Product Description

The Victron SmartShunt 300A 50mV Bluetooth Battery Monitor is an “all-in-one” meter without a display that turns your mobile phone or tablet into the display via Bluetooth and the VictronConnect app. Designed for clean and professional panels, it integrates a 300 A / 50 mV shunt and electronics in a single compact body (IP21), with a VE.Direct port to connect with Victron GX devices (Cerbo GX, Venus GX, Color Control GX) to enable local or remote monitoring (VRM). It accurately calculates SOC, remaining time, voltage, current, and consumed Ah, records history, and allows its auxiliary input to be used for second battery measurement, temperature, or battery bank midpoint. It is the minimalist alternative to the BMV-712 when a panel display is not desired.

Main Features

• Integrated 300 A / 50 mV shunt with M8 bolts and electronics in the same body.
• Bluetooth connectivity for reading, configuration, and updates via VictronConnect (Android/iOS).
• VE.Direct port for integration with the Victron GX ecosystem and remote VRM access.
• Configurable auxiliary input: second battery (voltage), battery temperature, or bank midpoint.
• Wide operating range: 6.5–70 V DC; suitable for AGM/GEL and LiFePO₄ batteries.
• Ultra-low self-consumption (< 1 mA) to avoid draining the bank at rest.
• History of up to 46 days of V, I, SOC, and the parameter selected on the auxiliary input.

Advantages or Benefits

• Clean and quick installation: no display or front wiring, all control from your mobile device.
• Professional measurement: ±0.4% accuracy in current and ±0.3% in voltage, with fine resolution.
• Space saving: compact format perfect for campers, marine applications, and technical rooms.
• Advanced management: with a GX device you get alarms, extended logs, and remote monitoring in VRM.
• Preventive maintenance: history helps detect parasitic loads and imbalances.
• Versatility: the auxiliary input allows monitoring of starter battery, temperature, or midpoint.

Purpose or Applications

The SmartShunt 300A 50mV Bluetooth is ideal for photovoltaic self-consumption systems with batteries, recreational boats, motorhomes, and special vehicles, as well as telecom and small industrial installations. Its IP21 rating makes it suitable for protected indoor environments, installed near the battery bank and centralizing visualization in VictronConnect or a GX monitor. Wherever precision, ease of installation, and a clear control panel matter, this monitor offers a robust and modern solution.

Technical Specifications

Compatibilities

Compatible with the VictronConnect app via Bluetooth; integration with Victron GX (Cerbo GX, Venus GX, Color Control GX) via VE.Direct; straight or angled VE.Direct cables (0.3–10 m); ASS000100000 temperature sensor; and VE.Direct Bluetooth Dongle as an extender if the environment attenuates the signal. Suitable for lead-acid and lithium banks within the indicated voltage range.

Contents and Accessories

• Includes: two positive cables with 1 A fuse (power and auxiliary input).
• Optional: temperature sensor, VE.Direct cables 0.3–10 m (straight or 90°), and VE.Direct Bluetooth Dongle.

Installation Notes

• Install the shunt on the common negative of the bank; all loads and sources must pass through it.
• Use M8 terminals and low-resistance connections (clean and tight); size conductors, fuses, and busbars for 300 A continuous.
• Typical Bluetooth range 10–15 m; metal chassis and hulls may reduce it. Alternatively, use VE.Direct Bluetooth Dongle.
• For environments with splashes or outdoors, choose the SmartShunt IP65 version.

Victron SmartShunt 300A 50mV Bluetooth Battery Monitor is a professional solution for demanding energy projects: it improves autonomy, organizes the panel, and gives you total control of the battery bank from your mobile device.
