How to build a $20 47A power supply

[BrianG]

Yeah, some chargers show input voltage/current, but they don't care if the supply is struggling as long as the voltage and current is there. And yes, increasingly loading down a supply until it shuts down can conceivably cause harm, but any decently engineered supply should shut down well before that happens.

Looking at your loosely judged "estimate" with 11 24v wires I should be able to safely assume 24v at 20amps I'd believe. That should be more then enough power to run this charger: Icharger 306B

Correct?

so if i buy this powersupply, it takes a standard desktop power cord is that correct?

And a spare servo connector will jumper the pins, no soldering for that? then i just solder up the servo connector wires correctly or add a switch and solder on my positive and negative and my power supply is ready?

Its not that i don't have the skills, but converting the atx supplies seemed like way too much of a hassle, but this seems really easy to do even with my 3 year old wrapped around my leg while I'm doing it :)
