Early days, but if anyone is thinking of battery powering a PICO outside
for intermittent use,  a nano timer and lithium primary cells looks to
be the best technology.

Why not 18650s? 2 would give you a little over 7V

"The maximum recommended input voltage for a Raspberry Pi Pico or Pico W

onboard voltage regulator"
 One cell should be sufficient for powering the Pico. The regulator
lower limit is 2.3 V so there is a need for deep discharge protection
on the cell.
 
I bench tested the device., Its not just a pico W. There is an ultrasonic device in there as well.
It stared to fail  around 4V.
