I’m interested in a way to keep the AutoPi (And the onboard raspberry pi) powered on for several hours after the car is parked. I am already running a bunch of other electronics in the car and have a secondary 12V lithium battery and charger already setup in my car. Is there a straightforward way to use this instead of the car’s battery with my AutoPi?
If it helps, I am getting the DIY edition. I already have a EC25 LTE module and a Raspberry Pi Zero W on hand that I plan to use. In the past I had also installed GPS and LTE antennas in my car (for a tracker I had built myself) so I’m all set to just plug in the DIY edition.
