i want add a Low pass filter between battery and 720watt ups inverter. because dc charging wires has some ripple voltage. I want to make it pure dc... charging voltage is max. 14.4vdc and charging amps between 10-20amps... and on inverter mode the same wires draw 60 amps at 10-12.6vdc approx 680watts to 720watts. my question is how to select Resistor value and capacitor value for this low pass filter?
