Like most of what I do, if anyone actually knows what they are talking about step right in.
Here is a chart by http://techlib.com/reference/batteries.html which is a good starting point although Wiki might be
a bit better
Putting AA batteries in Series keeps the same capacity increases the voltage but in parallel doubles the capacity with the same voltage so 4 AA batteries in series and parallel would give us 3V and 2400x2 = 4800 mAh.
Next the current pull from the PortentaH7 with Vision shield running an OpenMv or Arduino based Machine learning program.

I typically like really life experiments where I hook up fresh batteries and just let them run until the Arduino stops, but
most of us Edge Impulse Ambassadors have the Power Profiler II.
All we need to do is figure out the power drain during a classification and the power drain during sleep and then how much time in either mode.
Unfortunately I don’t know how to use the Power profiler. So I guess it is time to learn.

Anyone got the quick steps on how to use it with the Arduino PortentaH7?
