Hi Nick, The battery monitoring is multiplexed with the two ADC channels exposed on the external connector (i.e. ADC0 and ADC7). So you cannot sample the battery voltages and these channels at the same time. But you can switch between the two of them quickly if required.
See section 2.4.4. of the Shimmer User Manual for further details. See the FAQ page to see how to convert the raw ADC value you receive back to battery voltage: http://www.shimmer-research.com/links/faqs#S9. Remember to double the value due to the halving of the voltage before it is measured (as mentioned in the referenced section in the manual).
