How to build a $20 47A power supply

[mistercrash]

Pardon me if I seem ignorant, but is there any way to use those power supplies to build something as powerful as this.

I had a Rivergate PS years ago and I loved it. It was a 30 amp model which was perfect at the time. But although they are really good and powerful from what I remember, they are way too pricey.

Just bought one of these powersupplies. I was thinking of the 575w one originally posted, but the charger I want is 2x 400w chargers. While I don't own any 6S batteries alone my Jammin truggy uses 2x 3S 5000mah lipos and 2x 2S 5000mah lipos. I also have some adapters that let me charge two 3S lipos as a single 6S, same for 2S as 4S.

So I was figuring at a 3C charge rate that would be about 630w not counting losses so that would be maxing out the 575 and getting into bad territory.

The 1300w is only on 240v but on 120 its rated at 910w I think it was (12v x 75a). Which should still be plenty for the twin 400w model.

Realistically as i won't be using both 2S and 3S sets at the same time I'll be charging the twin 3S separately which is about 500w or so.

Glad I found this thread, was struggling to find a DC PS before I'd put money down on a good DC charger.
