Hi David,

You can measure the voltage level of batteries (using  VoltageC component)
during a period and then make a figure with the evolution of the voltage
level over the time. After if you calculate the mean slope you get the mean
slope that means the consumption (but it's the mean consumption and not the
instant consumption).

Best Regards, Antonio Rosa.
