They use the shunt resistance as a transducer to convert current into that voltage. The voltage appears directly across the shunt resistance, and thus constitutes a voltage drop. A current-measuring shunt is just a fancy name for a resistor. A 500A/50mV shunt is really a 5E-2 V/5E2 A = 1E-4 Ohm resistor, or 0.1mOhm resistor. Any resistor with
Shunt advantages and challenges for EV current measurement

Difference between a battery shunt and a watt meter?
In the generic sense of the term, a battery shunt is a device inserted into a current path. The shunt has a known precise resistance with measuring leads at each end of the shunt. Those leads provide a means to determine the voltage drop across the span. When combined with a measuring device, many types of data can be measured.

Then the shunt goes between that buss bar and the battery. Connect a wire or bolt the shunt direct to the buss bar and then a wire to the battery negative, which should be the only one going there. Hope that helps. Check out wiring unlimited for help with cable size its a really useful resource.
starter battery connection to shunt
The negative cable from the engine block goes to the load on the shunt AND the negative cable from the starter battery also connects to the load side of the shunt or directly to the engine block. Therefore, when you start the engine, the high current from the starter does not go through the shunt. Your old shunt was wired correctly.

6 FAQs about [What is battery shunt technology ]
What is a battery shunt?
A battery shunt is essentially a precision resistor, but it’s not there to resist change; it’s there to measure it. Imagine it as the weighing scale for your electrical system. When your system is on a diet of power, the battery shunt helps you keep track of exactly how many calories, erm, amps, are coming in and going out.
How does an electrical shunt work?
In the context of measuring battery capacity, an electrical shunt works in the following manner: Shunt Placement: As we have already seen, a shunt is placed in series with the battery’s negative. Voltage Drop: When the battery is used, current flows through the shunt, creating a small voltage drop.
