A simple battery voltage readout ( meter ) for those in need to know the actual battery voltage of their device for debugging purposes or other.

Batteries may suffer overcharge for various reasons and sometimes devices indicate the wrong state of charge. A fully charged Lithium Ion cell will have a voltage of around 4.3 Volts under charge - the voltage should ( generally speaking ) not exceed that.
