I have also designed a card that normally runs on the supplied 5 V, but switches over to battery operation it the input voltage gets too low. It then tells the pi to shut down, and turns off the power after about 30 s. The plan is that this will ensure that the pi is always shut down correctly, even if you just turn off the power. I have ordered the PCB, but I need to order the components and assembly it when I get the time...
Nice idea of a good mannered shutdown, I use a node red button to shut down Opencpn then the Pi, some sort of clever UPS would be cool as well.
Another clever design here -
