You understand that a 2S2P is a total of 4 cells? Basically, a pair of 2S lipos (2 cells wired together in series for 7.4v nominal) are wired together in parallel to increase capacvity (mah). You have a balance connector for each pair of 2S lipos and thats the extra lead you're seeing.
I'm not sure how you're going to balance this lipo though - can you supply link to this lipo on HC? I suspect they have some kind of adapter for it to use for balancing. Some balance adapters let you plug in 2 separate lipos, maybe this was what they intended??
