The Wild World of Batwoman (1966)

aka

She Was a Hippy Vampire

In this zero budget cheapie a busty Batwoman enlists her beauteous bevy of Batgirls (when they are not dancing the jerk) to help her regain a mad scientist's invention (an atom bomb made out of a hearing aid) before a costumed ne'er-do-well, Rat Fink, can glom onto it for his own purposes.
