I’m trying to power my HW 131 power supply with a 2000mah 7.4volt battery through the DC power jack connector, So that I can supply both my arduino uno and servo at the same time. Does a part like this exist ?

I cant seem to find a 7.4 volt battery in the sketch, do ineed to download a new part?
A google search of the form “fritzing part barrel plug” will find you available parts. There are no connectors on any of the barrel jacks so the connection won’t appear in schematic but only in breadboard.
Connect 2 3.7V batteries in series to make a 7.2V battery. There likely isn’t a 7.2V battery one of the generic batteries is the usual solution, but a google search for battery would show what is around.
