I recently bought a ESP32 Thing & Lipo battery on Amazon. I went to test out the Lipo battery (3.7V 1800mAh) and the magic smoke came out of the Thing! I'm sure I screwed something up, but I'd like to figure out where I went wrong. Got any ideas? Buyer beware on Amazon?

Here are the specific product pages I bought them on:

Looking at the pictures, I believe you connected the battery with the wrong polarity. The board shows a + and - label above the connector; you need to use a battery that has the red wire connecting to + when it is plugged in.
