Unknown Battery Connector
The connector type for the battery is not published. What is the connector type? Thank you.
That's 1.25mm connector

@Heltec-Aaron-Lee JST does not have a model "1.25". What is the p/n for the header on the board. I'll figure out the rest. Thanks!
The female half in that lot is what you are looking for, just received and tested they plug fine. The seller call it "micro JST 1.25"...
@DeuxVis ok, so then can you tell me which battery (preferably on Amazon) to purchase? Also, that connector is not from JST. Look here at what I can find w/ a 1.25mm pitch.
I haven't done any battery testing yet, but the guy who designed that printable enclosure has. Have a look in the comment section someone asked him about the battery model.
This said I tend to believe any single cell lipo should do. For reference some aliexpress seller pictures show a 1000mAh one used.
I'm using this board with this battery and, depending on your needs, I'm running for a couple of hours. The board came with the battery adapter and I just soldered it onto the existing connectors. What I'm still missing is how to read the battery charge state.
Is there something I need to do in order for the battery to work? Do I need to wire in a switch?

When I plug in a battery nothing happens... how do you get the battery to work?
[Solved] - I connected the a power supply at 3.5 volts to the + side of the micro 1.25 connector and the board worked as expected. The batteries I was trying before were reversed in polarity which I assume destroyed the ability to connect. So be careful to only hook it up after matching the polarities. You only get 1 shot
No idea. Never worked for me before.

I think Jimmy is right. See this. https://www.mouser.com/datasheet/2/276/0532617002_PCB_HEADERS-1510014.pdf The picture shows a 4-pin, but the ...7002 appears to be 2-pin judging from the downloadable step model.
