Well like most I used to run 2 Dps600pb power supplies like most on here, but the way I was using it, I was not using the 24v so I looked else where,
So after looking around I came to the decision to use the DPS 1200 FBA it's a hot plug server power supply and as I am only using 1 it does not need any modification, it's small and compact as well.
So the specs @ 240v input
1200 watts and 100amps on a 12v output,
Here she is,
And what I did to it,
Job 1. Remove server holding mechanism, now you can take the case off and remove the rivets and spring, but I covered the unit ground a grove in the arm as it leaves the case and put a small square of wood in the space to hold the sprung clip up to keep the holders in the case
Job 2. Then it was time to add the bullets for connecting the charger to, simple job of soldering to the hot plug,
Job 3. Make it turn on, you just need to solder a metal film 0.6w 560 ohm resistor between pins 33 and 36 as shown in pic,
But I did a bit more than just solder the resistor, I put in a switch in this line, I just used a few strips of servo wire, then put a small peice of 12 guage silicone wire sheath over the top of the resistor and solder ends to protect it, the switch mount is an old key ring ID tag cut up I wamted the switch on the end but did not want to restrict the air flow,
Just to finish it off a small peice of electrical tape to cover the exposed hot plug,
And the supply in its home case,

Re: KevG's power supply
Nice job Kev, just one thing wrong, the resistor is not 560 ohm, it's 680 ohms mate

Re: KevG's power supply
Ah but that's a generic photo I used to show the place to solder, I am led to believe you can use between 560 - 1000 ohms
But I used a 560 ohm and it works fine

Re: KevG's power supply
It more than adequate to charge the 4 6s 2700 packs I have at the moment at 2c and it don't really break into a sweat, the fan control seems to be better than the dps 600 units and when it's on its not quite as noisy either,

Re: KevG's power supply
Just checking bro on that resistor...lol
Don't think I'll ever get past 3S lipos...lol. But I should design something to charge more than one at a time....lol
Saying that my charger goes to 5amp, so a parallel board would do I think, I only ever charge at half C rating

Re: KevG's power supply
Geez tony you must be charging constantly, I do with my setup 4 batteries at 1c and I am done in 35 mins,
If You try and parallel charge with yours it's just gonna put a lot of strain on it,

Re: KevG's power supply
I am Kev, especially now, going through 4 packs a day at moment, but it's great fun..
Charger would only be running at 4.4 amp with them in parallel, should be ok. I'm using a PC power supply to feed it at 12 volts... I'll just have to invest in a better one if it burns out or fix it and modify the drivers
