IMO many Renogy products are simply repackaged versions of other products with a markup added. Very suspect that Power Queen and Renogy shunts look very similar - just rebranded graphics. Shop carefully. When you get outside the Victron umbrella, most products of this nature roll out of the same Chinese factory. You may as well buy the cheapest one... otherwise you're just paying a "name brand" markup for the exact same item. For details watch a few Will Prowse YouTube videos of teardowns/reviews.
Shunts all basically work identically... they measure power going into and out of the battery. All you really need is available amp hours in the battery. All the other stuff will eventually get old as information overload.
With a lead-acid battery, start with it fully charged. Wire the shunt to the negative terminal, and the power lead for the display to the positive battery terminal.
Connect the shunt and program in the amp hour capacity of the battery. Then set the display to 100% state of charge. The shunt will measure amps into and out of the battery and convert to "state of charge" percentage.
With lead acid, you should consider 50% SOC as being empty... you might cheat occasionally, but that will degrade the battery and shorten it's life.
Also with lead-acid, you should occasionally recalibrate as the battery ages if you want better accuracy.
A shunt that does the job without the bells and whistles is less than $35 on Amazon...
