Works great until it doesn’t
This is a cool app that tells you the state of charge of the battery, the current draw, and the voltage. The problem is that when the AIMS battery is fully charged, the battery shuts Bluetooth off. It’s kind of ridiculous, because from time to time you want to check to see the state of health of the battery if you’re using it as a backup. So when the app doesn’t connect to the battery, it might be because the battery is dead. Or it could be that the battery just shut Bluetooth off. But that’s not the fault of this app. Or maybe it is since it’s designed to work with the AIMS battery.
