If by p/n you mean part number it is Radio Shack 274-730 and the banana jacks are Radio Shack 274-725B
I also have some banana plugs that came with the charger that are smaller and screw into the casing (no part number)
From the picture Charlie P displays in the post above the banana plug just pulls of the casing. I guess you just carefully grab it with pliers and twist.
So I don't need anything more, and the connection I mentioned is correct?
EDIT: I just looked again at Charlie P's pic and it looks like thread screws that unscrew to remove the plug.

What is the p/n of the banana plugs you bought. Picture too fuzzy to read. Once I know that I may be able to tell you how to solder to that particular plug.
