F-1 - I'm sorry that no one has been able to answer your questions until now.
I can confirm that the 5000 and 5600 mAh packs, in 35C, 50C, and 65C flavors, are all 2S2P configuration. I'm not sure whether the original product description on the website was either a typo, or if the supplier has changed the battery configuration since the original units were received.
The website descriptions have been updated accordingly.
