ESP32 WiFi Kit using external battery

I have a 3.7V Battery that I would like to use on the ESP32 WiFi Kit.
The battery has a different connector that the on-board battery support

What pins should I plug the external 3.7V battery into ?

The battery can only be input from the connector on the back. In addition, if you buy our products from the official website, we should be the cable with battery connector.
