Electronic assembly provided with a parallel circuit for connecting electrically to two battery units

An electronic assembly (100) with two battery units (200,300) includes a system module (11) provided with a preset threshold value and a parallel circuit. The parallel circuit is coupled electrically to the system module, and includes first (121) and second (122) power diverter circuits. Each of first and second power diverter circuit consists of an LED member (1211,1221) coupled electrically to a respective battery unit and the system module in such a manner that a normal bias voltage is existed therebetween and an operation switch (1212,1222) coupled electrically to a respective LED member, the respective battery unit and the system module in parallel manner.
