Something like that- you usually need a pair of 2s female plugs (jst-xh, to go from each lipo), and a single 4s male plug that will go to your LBA10 (whatever type of plug that uses), then a series Y-harness to link the lipos in series & into the charger.

I have 1 question though- the xBase charger is a 50watt item right? If thats the case, and you charge the lipos at 1c (you didnt mention the capacity though), you may well find its hardly any quicker to use this special harness as the charger cant develop enough power to charge both of them at the full 1c rate (5amps for a 5000mah lipo for example)...
