Victron Lynx Shunt vs SmartShunt (best battery monitor for Van and RV power systems)

My issue is - my solar connection is on the 2 batteries along with 4 other grounds.

As a couple others have said, I'd expect there to be higher amperage on the Lynx Shunt because of the voltage drop. Lower voltage=higher amperage, since Watts is the only "true" measurement, at least in this context. If you convert both to Watts, they're a lot closer <10 watts.

The Victron stuff is very capable and very well-respected. They certainly think highly of it, if the prices are any indication. I would not use a Victron Lynx shunt in a Van setup; maybe in a really large RV? I've used Victron chargers and have a couple of their smart shunts in use, one for a mobile power station and one for a small off-grid setup. I've been very happy with the data they provide.

No way is a clamp on meter as accurate as either shunts. Most clamp on DC meters are no better than 4% and the best one I know of is 2%. I don't think you can conclude which shunt is more accurate, you need a better way to get a current standard than using a clamp on meter.

Appreciate this information. Nice job

With the lower voltage for the Lynx shunt (as it is further from the power source) it makes sense that amperage would be a bit higher to achieve the same power. 1.13KWh Lynx shunt vs 1.14KWh for smartshunt - Lynxshunt is further down the line so therefore would receive less power as some power is lost as heat in the line, no?

Love seeing that Ross Lukeman smile at the end of each video! ;D 🙏

I suspect if you were to check temperature readings on several different units of each device and temperature probes as well, you would probably see different numbers....Also if you calculate the wattage each shunt is reading they're pretty close, they are only 7 watts apart at over 1100 watts which is much less significant, thanks for video

Another consideration when sizing a shunt, is the resolution of the measurement (as converted to digital).
Measurements will be more accurate if the shunt is not oversized, especially at charging current (less than 100 amps)
