Lipo battery connecters ?!

[iamdigger]

Hi, I have bought same turnigy 5000MA 2c 40c lipos from hobbyking. http://www.hobbyking.com/hobbyking/s...dProduct=14317

However although the site says 5.5mm bullet dischange plugs, one plug is huge and the other small. The standard bullet connects that come with the turnigy lipo charger don't fit these connects/plug.

I'm new to all of this, am i missing a trick here or have I been supplied plugs that just are not going to match. (Will i need to source new connectors? Any advice/websites?)
