trumpy, yall don't have the big roll around chargers that you quick charge batteries in a garage with? they can supply 40 amps continously.you would need a couple of electrolic capacitors for filters to clean up the ripple , but should work fine.i opened up a regulated power supply & thats what i found.regulation would be done a lot by the capacitors , but i'm not sure how much. as for some big diodes i have some & would be glad to send ya a couple. these come out of a plating rectifier at work. belive they are 200amp ea.hope this helps!
