Hey guys... I got a new hobby that requires lots of battery charging...

I want to make a central power station using a PSU... I am planning to juice one of these (to charge 8 batteries at once), and one of these (which will charge this )...

I know most of you are saying that I should just get a power strip and run these chargers off of that, but I wanna do something funky and use the extra rails to keep a other small stuff running by wire that don't use plugs... I plan to strip the 4 pin molex's and use those. I know the yellow is 12V, the red is 5V and the black ones are grounds... I just want to know if a basic 350W PSU is capable of providing the power needed, and how much power those chargers require (if someone could figure that out it would be most important and the golden answer for the moment).

While we're on the subject, has anyone used a PSU to power other things besides computer systems and their accessories?

yes, i think that would be best

It is possible, but you would need to solder a series of resistors from radio shack or another electronics store. The chargers are specially built to accept AC input voltage and to give out a specific DC voltage to charge the batteries. Also, the chargers are specially built to stop charging the batteries after they are charged up to capacity.

My advice, just get a surge protector.

That's what i was going to say, all these are made to use 110/120 volts as intake power, you want to give them 12V that's not at all the same tongue.gif

get NiMH batteries instead of NiCd... they have a lot more capacity and therefore run/last a lot longer (your rc play time will last longer wink.gif)

you could make a voltage regulator circuit fairly easily to bring it down from 12v to whatever you need (1.5v or 7.2v for example) or you could even do it with a voltage divider (one fixed value resistor and a couple of other mini "preset" variable resistors hooked up to switches...

the problem, as has been stated above, is you wouldn't have any over-charge protection... and the current wouldn't be limited unless you added some other stuff...

dont be stupid, obviously your needing your batteries charged for your r/c car
get a powerstrip before you kill yourself

as for what power you would need to use both of those chargers, it will be written on the charger itself...... add both and thats what youll need

as for your other question
i have an old AT PSU on my desk right now powering a car radio tongue.gif

the roof, the roof, the roof is on fire
we dont need no powerstrip, let the motherf*c*er burn, burn motherf*c*er burn
