Thanks Elihu Stevens for the heads up. I might have been careless and connected the cells according to the markings at the base of the holder were it not for your review.The middle cell should be connected in the opposite direction to the marking at the base of its slot. This way, whether 1, 2 or 3 cells are connected the output voltage will remain 3.7V. So look elsewhere if you want an output voltage of 11.1V.
