BT Battery monitors

 As small issues crop up from getting Alice out of storage I find myself here more and more often.
 The screen on my audit panel went kerfluey.  Only lasted 26 years, disgraceful!
  Anyhoo....
  Does anybody know of a Blue Tooth compatible battery monitor? Something I can clip onto the battery terminals and use a phone app for readings?

Alan at Bay Marine Supply normally has a good price and good support.
Not clip on, must install included shunt to get accurate battery status.

You have both chassis battery and house battery leads/fuses under your flip up dash.  If all you want is battery voltage, buy a digital voltage display and wire it up. Yes, likely 1-2 tenths lower reading at dash than at battery due to wire runs, but pretty close.

Moby,
Here you go.  You can monitor 2 separate battery banks.  You can go to the Google play or Apple play store and check out their apps.

Looks like this Amazon battery monitor can measure voltage from two different battery banks, but it can measure amps from only one battery bank.

It also requires a separate external shunt for our high amperage battery banks.

I really like my Victron BMV 712. It will tell you a great deal about your coach batteries and it can also monitor the voltage of start battery. Usually packaged with 500 amp shunt which is appropriate for a Foretravel. Bluetooth works well and would be compatible with a victron solar charge controller if you decide to add solar in the future. I mounted mine in the battery compartment and purchased 16 inches of 4.0 welding cable to match my existing cable, lug and hammer crimp. AM Solar has a helpful video on the Victron BMV-712.

The Victron BMV 712 works quite well to monitor your house batteries, amps in and out and voltage as well as battery temp or the start battery voltage.  BlueTooth capability adds about $25 to the cost of the BMV 702 wich does everything else but the BT.

Please check Bay Marine for your inverter, battery monitors, isolators, combiners and all other of these type of supplies.  Their prices are competative, you might get a discount if you mention the FT Forum and their customer service is exceptional.  My kind of store.

Looks like 60 amps max without an external shunt, then circuit breaker will trip. That's only 720 watts, so you will have to watch your loads carefully or get an external shunt.
