Okay so going back to the 5s2p example, would all the + terminals of the first pack go on top of all the + terminals of of the second pack and the same with all the negative terminals and not just the + and - terminals at the ends of both packs, which make up the power/discharge leads?
Is this kinda the same thing? http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9910&Product_Name=2_x_3S_->_6S_Splitter_JST-XH__(5pcs/bag)
