You can indeed charge 2 x 2s packs at the same time. Firstly they have to be wired in series, e.g, one live + and one negative - joined together and then the remaining + and - go to the charger leads. The only issue which can easily be overcome is the balance port issue as you have two plugs consisting of 3 wires.
You can either make a balance lead adapter, or join both packs together permanently and fitting a 4s balance plug.
If you need a diagram on how to wire up either balance lead just ask and ill send you one across.
Hope this helps.
