I've been looking at off the shelf raspberry pi UPS/shutdown controllers. I've come up with 4 and wanted somebody to weigh in on the choices.
My use case is pretty strait forward. I want the pi to shut down gracefully when mains power is lost. I'm not fussed about any other functionality. I'm running a Pi2 - might move to a Pi3 at some point. Smaller form factor of UPS unit is nice but safe operation comes first.
Anything else I should be considering? Is the capacitor on the pisaver any safer than the lifepo4 battery for example?
Thank you raspi community :)
