Installing Battery Monitor

One of my projects that I am planning for over the winter is to install a Battery Monitor. Right now I am looking at the Victron BVM-700 as I already have a Victron MPPT solar controller and like how that is working and the Bluetooth connectivity option.

Question...how have you wired wired the monitor shunt connection if part of the load is directly connected to the battery and pulling power all the time (i.e levelers, BIM, etc) and the rest of it goes through the 12V disconnect?

You should move everything AFTER the shunt. The only thing coming off of the negative side of the battery should be the shunt. Otherwise, your measurements will be inaccurate.

Agreed. However, I am more interested in the logistics and wiring part of this project. Did other people install the shunt in the battery step well or somewhere else? Also, since I am considering a change in batteries, I might want to wait until I know what type of batteries (and dimensions) so I can plan the battery monitor install accordingly.

Installed Trimetric shunt in stairwell battery box. Plenty of room with original batteries

After I had mounted my shunt to the frame by the batteries I found this innovative bracket that someone had made by flattening 3/4"copper tubing. Easy, safe and low profile. Should have done it myself that way.

Now that's an innovative approach assuming you have enough clearance above the batteries.

I should mention that after getting a chance to read the installation instructions, this may be simpler than I thought. I.e. the shunt actually connects to the negative terminal.
