Multi-Batt Mon Battery Monitor

I bought two battery monitors keep tabs on my two car’s batteries. This app lets me check the voltage and daily historical graph from both at the same time! I can walk to my window and not even go outside and I know if my cars need a charge. I also tried it on my RV and was a great way to see basic solar charging voltage. I wish it would load in the background without hanging the app. That would make it 5 stars for me. I read some of the other reviews but decided to try this anyway. And I’m ha

It works pretty good, but as of lately the cranking test, charging test, trip, and my report buttons don’t work. When you push them, the app says synchronizing data and never does anything.

Great solution for monitoring car batteries. I have three EV's, two of which are famous for dead 12v batteries. With this I can only quickly do an instant voltage check but see how the sleeping EV is drawing 12v power continuosly with periodic recharge spikes from the HV battery. Very educational. Docs are adequate.
