Hi,
 
I am thinking of using Li-Po Battery to power my cDAQ which have 04 NI-9324 modules. As per the documentation, cDAQ requires 9-30 VDC and max power can be 16W. 
 
If I use 12 V Li-Po battery, then DAQ will use more than 1Amp of current. This means, if Li-Po is of 5000 mAh, then I may be able to get more than 3 hrs of operation.
 
Am I thinking correctly?
 
Thanks
