Mg Electronics Carbon Conductive Assembly Paste 847
I have never really tested this paste but it was recommended by a lot of people.
It is installed in my middle battery between the aluminium terminals and aluminium busbars. Hard to tell if it makes a difference or not. Time will tell, I guess…

Victron Smart Shunt
The Smart Shunt of the Victron Family. Shows the capacity and power/amps going in an out of your battery. It re-calibrates automatically every time the battery is fully charged. It also transmits the voltage and current to other Victron products so they get an accurate reading of this data.
Watch the video with all settings explained here.

A bit more expensive, a bit more functionality as the Victron Smart Shunt.
