Inverted polarity
Bought this battery for my ESP32-E, I'm new with this and tried to make an easy project, but after hours of troubleshooting found that the polarity in the connector is inverted. Hope my ESP32-E is not damaged when I get a new battery.

Warning: There is no standard for polarity
Be warned that there is no standard (or, there are two different standards) for the polarity of the JST connector found at the end of the leads of LiPo batteries like this one. The wrong polarity will let the magic smoke out of your battery management chip, or voltage regulator, or MCU--or even start a battery fire. The two I ordered came with the polarity typical for RC cars and the like, which is backwards from what you expect on most IoT devices, microcontroller boards, and so on. CHECK BEFORE YOU PLUG THIS IN! (You can release the pins from the plug with a tiny screwdriver and swap them if necessary.)
