How to build a $20 47A power supply

[Metallover]

Tonight when I was charging my 6s 30ah pack, my Hyperion EOS0610i charger failed while running off of the HP power supply in the OP of this thread. I doubt it was the PS's fault, but I thought I would post it here just in case. I was kind-of pushing the charger, but it hasn't failed after months of use until now. Also, I have lost a power supply charging this pack too; maybe my main is the culprit..

To fix this problem I just bought two more power 575w power supplies for $26. I'll mount two on some plywood and wire em up for 24v to run a new charger... Maybe a 1000w charger to charge my 6s 30ah pack??

I would be surprised if that works. More than likely, both supplies share a common ground, and when you hook them in series, you will short out the output on one of them.

I saw earlier in this thread something about it...

Here's good how-to on converting two 12v power supplies to one 24v power supply - http://www.rcgroups.com/forums/showthread.php?t=1164359
