I just purchased two of these (one for each battery bank) and was curious if anyone else had used something like this? At $40/pop, figured what did I have to lose. They are little modules that hard wire to each battery, then you download the app and it displays all sorts of info like voltage levels, DC amperes out, , etc etc, all on your phone/tablet. They arrive tomorrow and I'll test them out this weekend and post more.

Here's a couple of screen grabs from the app (which is $13 for the multiple battery bank version ..free otherwise). pretty nifty. You can custom program it to sound an alarm on your phone or tablet when the battery bank reaches a (predetermined by me) voltage level.

That's really cool. Thanks for sharing.
 
Those are really cool, but only if you happen to be at the boat. If you want something that can ping your phone when you are away, consider Boat Command. It uses cell for a small fee, and can let you track 2 battery banks, in addition to temperature, bilge pump activity, shore power, location, motion detection, etc. It also allows you to control up to 3 devices. I use it to turn on the AC when I'm headed to the boat for example.

Obviously more expensive, @ $300. Here's a screen shot of my Boat Command dashboard.

Very cool Bob. I would really love to have such functionality. The ones I got above really aren’t as robust as I was led to believe. They really just are a battery monitor to watch the juice while at the boat. They do seem to be pretty accurate though and should work while we’re away on the hook in July. I will definitely be looking into Boat Command in the future.
 
The first one looks pretty simple and straight forward. If I hadn't moved to a slip with shore power this year I would be quite interested. I was getting tired of having dead batteries at least 1x a season.

The second one looks cool as well. Interestingly, Brunswick recently launched a new brand / company called Nautic-On that performs similar vessel-monitoring tasks. It can provide a deeper integration with Mercury and Mercruiser engines, however, with Smartcraft integration that can send alerts to a servicing dealer. Seems kind of like an active maintenance solution in it's fully-configured form. It looks to be much more expensive though. Link to article on Panbo.

I've been using boat command for a few years now and wouldn't live without it.
