That's why I asked about the possibility of boosting the 12v to something like 14v. The higher voltage will require less current for a given wattage the charger is pulling. 47A @12v = 40A @ 14v. 47A @ 14v would get you an extra 100w out of it...

PSU didn't shut down at 47A limit. Good stuff.

I understand the higher voltage efficiency BG. The PSU server team said that it will be too much of a hassle to tweak the voltage. Those Server PSU are too tightly regulated, compared to the ATX stuff. I do have another PSU that goes about 68A, 80A@220VAC. But I have to figure out how to turn that sucker on.

I'm just a happy camper that I'm able to charger my A123's at 25A~10.8C. The charger reads 12.8V for the PSU under load. At rest it's 12.4V.

j, where'd you get yours from? I only found them for $15 plus like another $15 shipping...

Can you post the physical dimensions of this psu? Thanks

I'm contacting the seller to see what shipping to the Netherlands would cost.

My 50W charger isn't cutting it anymore :lol:

Good luck! I tried it too, and the cheapest option to New Zealand was $50 US. :gasp:

11"x3"x2.25"

any idea if these would work?? they should be 100+amps...

They will all work, if you know how to turn them on.

Yep... you just need to find out what pin combination will start the 12v rail... maybe you can do some research on google (also rcgroups...
lots of guys doing mods on these power supplies)... l am sure someone figured it out already.

No, but you can use them in parallelel.

+ with + and - with -

So you double the amp.

Same here :(

''Hello, Sure we will ship to the Netherlands.

Priority Mail is $50 and Express Mail is $65

- trademoon''

That sucks.

ebay


I grabbed the last one I saw at that price :na:


Im sure more will show up if they haven't already.

I was able to get 2 of them for $25 shipped. They should be here tomorrow.

I send an email asking how much if would cost to ship 2,3,4, and 5 units. If shipping will not get $50 more per unit I might just buy a bunch and sell them here *fingers crossed*.
