In the UK, maybe I would look at these: https://shop.pimoroni.com/products/jst-2-wire-assembly
Adafruit also sells them and is carried by several different distributors. Maybe just Google "adafruit jst ph".
The 2 links you posted both appear to be correct. I'm not sure if the Farnell one comes with the actual pins, and if you'd have the proper crimp tool to do them yourself.
Thanks for the link to the JST wires, you were right the Farnell ones don't have any pins. I've just ordered a set today after my batteries finally turned up yesterday.
