The Victron SmartShunt 300A is an all-in-one intelligent battery monitor that delivers 99.6% measurement accuracy, giving you real-time visibility over your battery's state of charge, voltage, current, amp hours, and estimated time remaining — all from your smartphone via the free VictronConnect app over Bluetooth. Rated at 300A continuous with a 500mV shunt drop, it supports all common battery chemistries including lithium, AGM, and flooded lead-acid, and connects to the broader Victron ecosystem via its built-in VE.Direct port for optional remote monitoring through the VRM portal. SafetyShield+ technology and configurable alarm notifications mean your battery bank is protected even when you're not watching, while up to 30 days of onboard history lets you analyse trends on the move.

Ideal for Australian caravanners, RV travellers, and 4WD tourers who rely on a healthy battery bank to power fridges, lighting, inverters, and camp essentials, the SmartShunt 300A retrofits into any existing 12V or 24V system with minimal wiring — no display head required. Whether you're crossing the Nullarbor, setting up at a remote bush camp, or living full-time in a motorhome, this compact shunt gives you the confidence to know exactly how much power you have left before you're off-grid. The optional AUX input lets you simultaneously monitor a starter battery, balance a dual-battery bank, or connect a temperature sensor for climate-compensated charging — making it one of the most versatile battery monitors available for serious Australian off-road and touring setups.
