Why do you want to double the o/p volts ? The size of the caps affects the output impedance of the doubler, but you will not of course be getting any more energy from it.

Thank you for reply,
I was going to up the voltage from a stepper to 18v to my diy regulator down to 13.8v for the sla charging (albeit I am aware when you voltage double; it does that by the expense of the amper) but it is ok because this stepper puts out 200ma and I need half that for my charging as long is voltage is correct.

Question is:
four 2200mf 25v caps vs 300mf 300v caps which will be better?
I have 50 each kind in my arsenal..

thanks
