Hey Tom, there is the positive red wire that runs all the way toward the top of the pack. What i did was put a small hole toward the rear of the pack and pulled the red wire all the way out, the cut it to the length i need to make the 10 cell pack work.

Now in order for you to make this set up work one of the batteries needs to be turned the other direction, so you will have the balance connectors at opposing ends of the pack. Let me know if you want pics
