A battery voltage checker circuit that used for measuring the voltage of a 12V. battery. 8 LEDs are used for showing voltage of a particular measuring region. Whenever battery is connected to electrical fan, solar cell lamp, light bulb etc. and being used, its voltage will be decreased and used up. In such a case, it will shorten the battery life. This circuit will indicate the battery voltage status throughout.

Technical specifications:
- Power supply : Not required.
- Consumption : 56mA max.
- Having 8 LEDs for showing voltage at each measuring region.
- Having damage protector for short circuit.
- Having a trimmer potentiometer for adjusting the voltage at each measuring
region.
- PCB dimensions : 3.79 x 2.47 in.
- Recommended housing : Future Box (FB13).

Kit requires assembly by soldering!
