    New phase of a project.

    I have a 24 Volt source charging some storage Caps.

    I am charging these with a resistor and LED in series
    and a second resistor of lesser value in parraelle.

    My theroy behind this is that the current will take path of the lower value resistor to charge the caps while for a time also go through the LED.
    When the LED no longer is lit this tells me through my trial and error that I am about 80% charged.

    I now need to indicate that I am charge to above 80% with another LED.
    Would I just use a high value resistor say 2.5K to do this I am aware that this will deplete my storage in the caps but only very slightly. The caps are about 10,000 uf @ 50V

    The ultimate aim is to show charging and charged for the storage caps.
    I am unsure if I have used the best solution so any pointer would be great.
