The basics: what is a shunt?

Let's start at the heart of battery monitoring: the shunt. A shunt, also known as a current shunt or shunt resistor, is an essential measuring instrument used to measure the current flowing through your batteries. The shunt is placed in series between a cable and measures the current passing over the shunt. The measurement is made via a small voltage drop created across the shunt - this voltage drop directly indicates how much current is flowing through it.

With the Victron Lynx Shunt VE.Can you get an accurate picture of your battery bank's energy consumption. This smart technology calculates and displays the status of your batteries, so you always know what the current state of charge (State of Charge, SoC) is in percentages. This way, you avoid nasty surprises!
