I recently bought an OBDeleven - base model, no credits / plan - and am getting used to it. At the moment, my primary interest is in the 12V battery and related systems. The app provides "Live Data" for this, but it's not clear whether the reported battery current is into or out of the battery. I think it is into, given the way the current showed a negative spike when the doors locked or unlocked. I also wonder where the battery voltage is being measured, as the app is showing a significantly higher voltage than a simple voltmeter connected to the battery terminals.

Has anyone else used this area of the app? If so, any comments?
