I have been around ours when we were charging at 180 amps through it (500 amp shunt) and it did get warm, but not so hot you couldn't touch it. I wonder how warm it would have to get to be an issue, and what the issue would be (accuracy?).
The BMV-700H comes with a shunt box so I'm now wondering if power dissipation is really a problem at all. I know the shunt could dissipate up to 25W but maybe all the heat will dissipate in the cables? Copper has a high thermal conductivity.

I would opine that the shunt box is for use in any possible wet location, not as a heat shield. It also would prevent accidental shorting across the shunt. My installation is inside and well protected and my victron did not come with the box.
