rearviewmirror Posted June 11, 2009 Share Posted June 11, 2009 So here's my Corsair benchtop power supplies. I am using them to drive Hyperion Duo II chargers. I originally did the 400w PSU, but 30A wasn't enough to charge 4 batteries up to 10A each. The 850w is quite capable, but right now I'll just drive each charger off of its own PSU. http://images49.fotki.com/v1510/photos/1/1042124/6997235/610200994548PM_0003-vi.jpg Link to comment Share on other sites More sharing options...

rearviewmirror Posted June 13, 2009 Author Share Posted June 13, 2009 Wow, haven't seen a mod quite like this before, but it looks pretty clean, good job! What are the batteries used for? I run Hyperion Duo II R/C car chargers off of them. I'm running 18.5V Lithium Polymer batteries that are charged ~5A each. I can charge 4 batteries at the same time with a max capability of 40A charging capacity. The Corsair's have a 3.3V, 5V, and 12V output which is nice since there are many benchtop uses for the lower voltage. The build of these is quite simple, you just a 10w 10 Ohm resistor to the 5V rail and put a switch on the green wire to simulate the motherboard signaling "power on". I like having both switches because my manual switch will also discharge the capacitors. Due be careful if attempting, these 70A+ PSU's are no joke and can deliver a nasty shock. Another comment on the resistor on the 5W rail, for some reason this will boost the 12V voltage a bit which is good. I wish these were 13.8V PSU, but 12V will do.

rearviewmirror Posted April 30, 2010 Author Share Posted April 30, 2010 So after using these PSU's for a while I'm still wishing I had a bit more voltage, something in the 13-16v range. I am still trying to think of ways to boost the voltage. Anything up to 28V would be fine for my application. Any thoughts? Link to comment Share on other sites More sharing options...
