Hi, I am trying to connect 3.7v LiPo battery to the JST input connector. This doesn't seem to power the board. Is there a switch or tab that needs to be removed / enabled for this power input to work. I thought I saw somewhere the tab between to the two pads on the underside of the board needs to be removed. Thanks for your help in advance.
At this point I can only guess and say that Vin needs 5V per the specification. Posting a schematic, not a frizzy picture showing all of your connections as you have wired it would be a big help. Also post links to technical information on all the hardware items, azon links are normally useless.
Cable colors on JST socket can be different on each producer. I think there is no standary for it. I bought a dozen of lipo battery connector + pin cable color was black - pin color was red. Beacuse of it check polarity of battery. https://docs.arduino.cc/static/f8e6dcb45bbccfc39cb309e234cd75a3/ABX00029-pinout.png
