do this come in a 48v version?

Hello, sorry, this item can only work with 12V battery.

How many amps can this unit handle?

This isn’t to deal with current. This is measuring voltage.

I already have one of these installed on my 2 rv house batteries, can i add another on my chassis battery and monitor it on the same phone?

There are 2 apps (iPhone) for monitoring. The free one only connects to one. I have three banks to monitor simultaneously so I gladly paid $10 for the 4 bank monitor app. I have a love / hate relationship with it. It could be awesome. The 24 hour graphs of voltage readings at 2 minute intervals are incredibly powerful in knowing how your banks are responding to loads and charging. I can count the number of times per hour my refrigerator or furnace kicks in, and see the effect of partly cloudy skies, and much much more. But instead I have to beat it into submission often by killing it and restarting it. The app is very amateurish, probably written by a junior programmer with little understanding of our needs and little guidance. I wish they could open source details about the meters and let the world make a better app.

does the unit constantly eminate bluetooth signal / electromagnetic radiation?

Yes, only about a 20ft radius , where did you come up with the radiation stuff
