Keygrip, I know a battery is in effect 6 x 2v cells in series, so connecting 2 batteries in series is like simply making one longer battery twice the size. But, if you have just one 2v cell, are you saying the current (amps) is the same as if you had 2 whole batteries connected in series (if according to the logic, connecting 2 batteries in series still only keeps the current the same)?
