I have a pcb with two 3mm holes for the positive and negative from a 12V battery. I need some sort of connector to solder in the holes for wires to attach to. The holes are separated so I must have two individual connectors rather than 1 connector with two connection points. I was thinking of pin headers but they seem to be only suitable for smaller holes. The holes are too wide to attach the wires directly. Whatever I use must be narrow as the holes are quite close (either side) to a capacitor.
