This may sound like a silly question and possibly I should already know how to solve it.
I'm looking to get a DC supply together for some radio gear and I'm looking to do it as in-expensively as possible, but with any equipment necessary.
I need a continuous current capacity of 30-35A DC @ 13.8V +/- a certain amount of voltage.
I need the supply so that it is as ripple-free and as regulated possible and not an SMPS that could interfere with the radio gear.
I was thinking a car battery, but would a standard charger be able to keep up with the current draw?.
And the amount of current flowing in and out of the battery cells damage it?.
Anyone have any better ideas, I've built DC power supplies before, but never with this size of output.
Helllppp!!. [Linked Image]
