Whats the least expensive way to make a power supply which can supply five, 5V @ 5A outputs, continuously?
I wish it was a flyback SMPS with a hand wound transformer, but I have a feeling it would have to be a HUGE transformer.
Five individual 5V 5A power supplies?

May not be the cheapest, but one of the easiest will be to buy a computer PSU with the 5V rail rated for at least 25A.
-- Methinks he wants five _separate_ supplies.
-- Buy is probably cheaper than make.
Inter-isolated outputs?

Its for simultaneously charging and balancing 5 lithium phosphate 3.7V cells. Using 5 seperate supplies makes the balancing much easier because you simply charge them independently until they all reach
4.2V. I say loosely regulated because Ill constant current voltage limited circuit to take the roughly 5 and limit it to 4.2V.ElectronDepot website is not affiliated with any of the manufacturers or service providers discussed here.
