The charge balance connectors are typically JST PH connectors on a 0.1" pitch (though might be 2mm - it think that's JST XH). They bring out the two ends of the battery pack (the same as the high current connector) and every junction between cells. So the 2s charger on the BBBlue has 2+1 pins and the 4s connector on your battery has 2+3 pins.
The outer pins, if connected to the BBBlue, will provide 14.8 - 16.8V and this might be OK to power the BB although it will not be able to charge it correctly using the charge balance wiring. I'm not entirely certain that it will be OK - the DC jack is rated to 18V but the charge connector is only expected to supply 8.4V to the pack and may not tolerate the 4s pack. Since you aren't able to charge it that I would think it would be safer to use the DC jack as Graham says, though you will need to fix the connector in as they won't stand much vibration and it's likely to fall out during flight. You will need a wiring harness to connect the heavy current output from the lipo pack to the motor controllers. You may be able to buy this ready made and add a wire to supply power to the BBBlue (it might already have a controller power connection, or the speed controllers might have a 5V output for it). If you make it up from individual connectors, the part for the battery pack is called a TX60 (or the larger TX80) and is easily available from ebay or quadcopter supply sources. The same connector is probably used on the motor controllers, or they might be fitted with one of the other standards. Quite often they have no connectors fitted as there are a number of different options alongside TX60.
