Need some help with LED wiring

Hi, I am hoping to hook up a Lithium Ion battery to a three wire LED. Hopefully this is the right place to ask.

The LED has the regular three wires, but the battery has either a female or male plug. The other male goes to the battery pack.

Best way to go about this? Is there a plug adaptor I can use or? Here is a pic: http://imgur.com/YJgibpD

Thanks for the help!
