I'd like to buy an extra battery for PSP Go but the replacement battery does not have those little plastic connector clip things on the end of the wires which are required to connect the battery to the PSP circuit board. Does anyone know what these little plastic things are called, where I can buy them or how to attach them to the wires? Do I need a special tool to do it?

These connectors look very similar to the plastic connectors you see used on RC car battery packs, if that helps. I assume they would be called the same thing?
