Dear Pi Forum
I have looked through previous posts but I am still uncertain as to how to power a Pi from batteries.
I want to configure standalone Pi systems (2+) to take wildlife photos - example: positioned in front of fox/badger sets to film/photo when movement. I have the Pi with camera part working already but I now need to put them into camouflaged boxes (again, all ready to go) with a battery which lasts as long as possible.
Portable phone power banks
Hobby boat batteries
Thanks in advance...
