Abstract
A voltage monitoring and controlling device (1) adapted for attachment between a power source and a power discharge terminal, characterized in that the device includes circuit means to indicate whether the voltage level in said power source is below, or at a first predetermined minimum threshold value. The device (1) also has means (6) to detect incorrect connection polarity and means (16, 17) for the prevention of voltage surges beyond a second predetermined value from the power source.
