My 6S Hyperion lipos are the same, but they were labeled A and B. I just soldered the the short wires together and put my connector on the long wires. Did you receive a Y harness for the balance taps? They came with my Hyperions so you can charge as a 6S.
No Y harness no labeling, nothing, I guess what Nitro said makes sense.
A short black and long red for one pack and vice versa, still unclear on what tap goes with which pack. I guess I could cut the red wrap off and have a look, then rewrap it. Think I'll wait to do anything to it and make sure it even fits the FLM tranny forward chassis for the Savage when it arrives.
