Thing Plus Artemis - LiPo Batteries not Working

I recently purchased a Thing Plus - Artemis, and I can’t seem to get it working with any LiPo battery when connecting to the JST connector (I have tried several different batteries). If I connect the battery directly to the VBAT/GND pins, they power the board just fine. Am i doing something wrong? Is the board possibly defective and not drawing power from, or charging the batteries via JST connector?

The JST connector is connected directly to Vbat and GND. Is the battery polarity correct? The red wire should be on the side closest to the Vbat pin.

Thank you so much Mike! I have no idea how/why I didn’t think of that, just assumed it was a “standard”. I flipped the wires on the connector coming off the battery and it works now!
