Not sure if you blokes have seen these, I've been running a pair for a couple of months now and recommend them for a quick check of your battery voltage. App can support multiple devices, just not on the screen at the same time. Labelling of each Bluetooth unit in the app is possible to make it easier to identify which battery you are monitoring at any given time. I have one labelled 'Main' connected under the bonnet (hood) and one labelled 'Fridge' connected across my second battery in the rear. I think the claimed current draw is 1mA. The app has a few other features, some useful, like the graphing of voltage. Graph image shows the cycling of my fridge compressor.
