If you want to keep the packs separate, it is possible to build a wiring harness that will let you use and also charge the two packs as a single 4S pack. It's not a great idea though, because if you ever hook it up incorrectly you could potentially damage your charger.
I made one for a pair of those maroon Flightmax hard case packs, which I was going to run in my buggy. I figured if I decided later to run 5S I could buy a single 5S pack, and then split the hard case pair into two 2S packs for 1/10 scale. Unfortunately, while the wiring harness worked great, the frankenpack didn't fit in my buggy with the wires plugged in (it was more than a bit too tall) with the body on.
