Here is the female end of a Lithium Ion battery connector for an MP3 player, I need the male connector but am not sure what these are called.
That looks very much like part number 455-2920-1-ND.
I’d recommend taking a look at the diagrams in the datasheet (linked here) to see if it matches up with the specific dimensions and footprint of your connector.
Thanks! Order placed… I was able to find the male counterparts here: ACHF Series Connectors - JST Sales America | DigiKey
