It depends where the leads connect on the other side of the board. I'll bet there is a pair that connects directly to the cells.
I tend to agree with Firedog. E+ did a great job of making their gear hack-resistant. My experiments with an E+ LiPo controller have been the same. When it worked, it was great, but it mostly didn't work. When I settle on an alternative, you are welcome to my one remaining hub battery controller and any other parts you may want.
