Easy schematic usefull to control battery voltage level. We can put in this circuit a normal 4,5 V battery, all led's will be on if the battery is full charge. (4 leds on => full charge, 3 leds on => medium charge and so on...)

Nice example, for the sake of reducing over all current, consider increasing the input resistors by the power of 100 or even 1000 and using low power Leds on the output (1.7v 2mA).
