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 is 5.5V. Powering the board above 6.0V will permanently damage the onboard voltage regulator"
 
and battery holders
similar to the AA types are available. The TP4056 charging modules are
inexpensive if you want to incorporate USB charging.
The Energizer lithium primary cells are a lithium iron sulphide
technology.  I have measured the cell voltages of about 20 new
cells and found them all to be between 1.800V and 1.805V open
circuit.  This would make them completely safe for this usage.
They maintain a voltage above 1.5V for much of the discharge
curve and most importantly they are unlikely to leak.
