The easy way: Hooking shunt up to fuse/converter box?

Besides dropping a tenth of a volt or so, what would be wrong with installing the Victron BMV-712's shunt inside at the fuse/converter box's 12V terminals, instead of within the outside, damp battery box? Seems like it would save some work as well as keep the shunt high and dry??

Always install in a dry place, the circuit board on the shunt doesn't like moisture.

Thanks, Boekel -- that's what worries me, because all of the pictures of installation show the shunt at the battery that is within the damp external battery box on the A-frame hitch...

I personally recommend it install the shunt inside the DC distribution box, where it is safe and dry.

As you mentioned you do compromise the accuracy of the battery voltage reading the further you place it from the batteries. If the run is very long, or accuracy is very important then you may wish to provide it with its own enclosure closer to the batteries.
