Where to connect smart shunt
If battery 2 is wired in parallel with battery 1 then you do not need to connect the aux terminal. If the red wires join, the shunt is in the correct position, but to be honest, it is weird that the red wires do not join directly at the battery, like the black one does. It would be best to work out where each battery positive lead go to

Remember that in a DC power system like you have, fuses prevent electrical fires by protecting WIRES, not the devices connected by the wires. This is not to say that blowing a fuse never prevents damage to an attached device, but that the "correct" way to think about circuit protection is to examine the circuit topology and identify faults which could result in a

Is my setup correct for 2 lead acid batteries wired in parallel for smart shunt 500? Does it matter which battery Vbatt positive is connected to? Connect positive to either battery. Do you have a connection between negative and chassis. If not then no worry. If you do then this should be on the load/system side of the shunt. Comment.

You need to connect the vbatt+ to exactly the same place that your loads and charging positives connect to. That is the voltage your MPPT or MP is "seeing"., so what you want the shunt to measure.

PZEM-051 SHUNT. How to install
The main neg cables should be connected to the "large" screws (on the outsides of the shunt) the two smaller screws (on the inside) need to be connected as shown. Note that the correct wire needs to go to the load side of the shut vs the battery side of the shunt. the other 2 wires on the shunt are battery pos and neg to power the shunt.
Adding a Bus Bar for Negative terminals to Smart Shunt
Meaning does the last stud need the wire going to the shunt? Or do i need the bus bar at all, and i could just distribute the negative wires across both posts of the Shunt? Right now, i had Battery 1 negative going to the left side of the shunt, and 5 other negative wires going to the right side (negative from battery 2, negative from bilge
Where do I connect the smart shunt negative?
If you have a buss bar that''s ideal. Take everything there, chargers, loads, everything. 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.

TBD-Smart Shunt Notes
There is some confusion about using a shunt that is connected in the negative lead of the battery compared to one that uses a donut around the positive wires. The donut has access to all power going in and out of the system. The ground connected shunt has access to all power going in and out of the battery. There is a difference.

6 Frequently Asked Questions about “Do lead-acid batteries need to be connected to shunt wires ”
Why do we need a shunt on a lithium battery?
That's why we need a different device to measure the state of charge on a lithium battery. A shunt is a device you install on the main battery negative in your system. It measures all the energy going through it, both charge and discharge. Let me show you a diagram: How Does a Shunt Work?
How do you wire a battery shunt?
Wiring a shunt is relatively easy and is similar to other brands. Connect the main battery negative to the shunt to B-, then use another cable from P- to your main negative busbar. After the main negative busbar are your loads and charging equipment. So, all the power going in and out of the battery is going through the shunt.
What is a battery shunt?
A shunt is a device you install on the main battery negative in your system. It measures all the energy going through it, both charge and discharge. Let me show you a diagram: How Does a Shunt Work? A shunt is a resistor known for its precision, allowing for accurate current measurement.
What is the voltage curve of a lead acid battery?
The voltage curve of a lead-acid battery is predictable. As you can see in the following image: We can see that 50% equals 51V for the lead acid battery. However the Lithium battery curve is very flat, making it hard to determine the state of charge. Here, 50% could be between 56V and 57V, which is 20-80%, which is a huge difference.
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.
Can a 12V battery be connected in series?
When creating a lead-acid battery bank with a higher voltage, like 24 or 48V you will need to connect multiple 12V batteries in series. But there is one problem with connecting batteries in series, and this is that batteries are not electrically identical. They have slight differences in internal resistance.
