“I really like this but in the end it wasn't right for my project. I've given it four stars rather than five because I spent a while investigating which pins on the pi needed to be soldered to which holes on the Lipo SHIM and felt this could have been included in the documentation. If you're wondering, solder pin numbers 2 and 6 (5V DC and Ground) to the holes in the Lipo SHIM then you're good.”
“This is a good device and it does exactly what it says it does. It's small and neat and doesn't preclude fitting more expansion boards. I'm using it with a pi zero w for a hand-held device. The downsides are that it's quite expensive (costs more than the pi zero it's powering!) and it doesn't handle charging. That's obviously do-able (Arduino Feather, for example) and without it the device needs disassembling to charge.”
“I love this little guy. It works precisely how it should in every respect.
Pros:
-Fits perfectly on both the Zero and on the A+.
-Super easy to set up.
-Software is a breeze to install.
Cons:
-Does not charge. I won't take a star for this. I didn't read the full description. That's my bad.
-The pin connector could be shorter. It stands fairly tall when assembled and it's not overly suited to projects that want to be flat.
Something like the half height pre-soldered adapters like on the Joy Bonnet or the Pimoroni Explorer Pro would be perfect for this.”
“The LiPo Shim does a great job, I'm using it in a battery powered PiCam. The only problem I've had is the battery will often recover after the Pi has been shutdown. This causes the Pi to start up again and then shut down almost immediately. The shim could do with more hysteresis in the battery level sensing.”
