Review on 💡 Geekworm Raspberry Pi UPS X728 V2.0: Power Management Board with AC Power Loss Detection, Auto On & Safe Shutdown Function for Raspberry Pi 4B/3B+/3B by Shane Schobinger

Ok to be honest I have a couple of these and they generally work well and I like them so I ordered another one. just got version 2.0. It looks like a complete redesign (look at the 1.3/2.0 photos and you can see the differences). THE BIGGEST DIFFERENCE THAT GOT ME A PROBLEM is that the BATTERIES are oriented differently than previous versions and of course I just pulled the battery out. Batteries out of the old and put them in the new and massive smoke. Yes, I wasn't paying attention, so this is a warning you should. On the other hand, CHEAP, SIMPLE DIODES maybe prevented my problem. So now I have a cool looking paperweight.
