I think it's just a different style of balancing. I'm guessing the negative wire comes off the negative battery lead and then one positive from each cell. In a vpx drill a123 pack there is a board inside. IDK if there's a board in the a123 racing pack, but that would also help back up my theory.
A123s really don't need much blancing by what I hear. I think you can just slightly overcharge them and then they will be balanced. Don't do that just cause I said it though.... I've never done it myself.
