Converter to use standard 1S lipos on some Losi Micro trucks, tiny Walkera Helis, and the Traxxas QR1 Quadcopter

Standard 1S micro lipo Female to Losi Male - 28 gauge, about 1" long

Note that you must insert the pins yourself, but they'll have wires attached, just as pictured. This is because Losi and Walkera (and QR1) have the polarity different, so you can safely buy this kit no matter what your intended usage.
