I bought one, but haven't tried it yet. The implementation seems relatively straightforward, and I like the idea that the PI will run for a decent amount of time before it detects a low battery and initiates a shutdown.
I'll post when I get time to put it all together. The hat comes with pointers to python scripts that do the shutdown. At the moment, I'm trying to come up with a good enclosure for everything, as the UPS won't fit inside of the PI cases that are normally used.
EDIT: Well, I guess you'll have to wait a bit longer for that review. I plugged in the unit, it seemed to working correctly and my PI started up, then the PI went dark. I fiddled with it all for a few minutes, looked underneath and realized that my nice cooling fins stuck to the top of the PI processor were touching the circuit board for the UPS. Oops. I must have shorted something out. It appears that my UPS is still charging the battery but not supplying power to my PI. Lesson learned. I'll order another board and start again!
