Charger + Power Supply.. Good to go?

[cbr shadow]

I bought a:
Dell Power supply 700w 57A @12v
from another member of the forum. I also ordered an icharger 208B battery charger from EP Buddy. I should have double checked before ordering, but are these compatible and am I good to go? Power supply was inexpensive @ $40 incl. shipping, so I figured I'd just go with it. Thanks for any input

edit: Meant to mention, these will be used to charge my Lipo setup. 24s3p, 88.8v 15Ah.

Well, it will certainly work. How well, will depend on what type PSU it is. Sounds like a PC psu, in which case, it may limit your charge rate unless you do some mods on it. If it's a real 12v PSU that has a voltage adjustment, then it will work well.

the 208B only does 8 cell charging.. so you are going to be playing with wires and harnesses !!

You're talking about for balance charging, right? I dont plan on balance charging every charge, so I was going to balance charge them in (4) groups with a 1-6 balance parrellel harness from epbuddy. Then for normal charging having all of my packs in parelell and charge all at the same tme - sound right?

'will work, but as the man said "you're going to be playing with a lot of wires/connectors."

Best thing IMO is RC charger to get everything reasonably balanced. Put that away and do a serial bulk charge most of the time. Trouble is, that means you need a higher voltage power supply than the one for the iCharger. And then, you really don't need the large iCharger as much, oh well...

I serial bulk charge to 62V or thereabouts. Been over a year since I broke up the pack into bricks to put on iCharger. I watch the CellLog and when one needs a little voltage bump 1S charge and fill it through the balance connector with an adapter for the main charger output.

Or, use a cell phone wall wart but I'm not a huge fan of those since the ones I get seems to float up over 5V and that's not a good idea for RC Lipo. The iCharger does 1S just fine...

I have an icharger 208 B unit with a paraboard, I use it to charge my four 6s packs(6s 4.5a life) at 2 times rate (4.5a x 2=9.0a), I only have a modify meanwell with 600 watts and 25a. So, your power supply got more juice than mine. I hope to do bulk charging as soon as I really understand what to do, after 6 months, I am still a newbie with all this electrical stuff. I guess I am a hardware person rather than a software person.
I balance charge after everyride, this takes me a few hours, as I do 2 packs at a time.
i am looking for another charger, one that has AC power, as I want to leave it at my work locker, but I think their max wattage rate is 50 and max amp is 5a, that will take forever.

100v 4.5 amp solution = 450w one plug.

Its not as complicated as it seems especially if you are balancing every so many cycles.

Essentially he will be paralleling 6 batteries at with premade 6 to 1 cables that parallel the balance taps and the main leads to balance charge his packs in parallel. He said he had 18 packs so this will be done 3 times. ... I have 24 packs with 6 pack groups and and im totally not phased by this task. Doing this everyday yes there is room for error with all those connections but taking your time for 1 day of balance charging for a few hours every 3-4 weeks is not that much of a hassle.

He just needs to make sure he cycle and qualify and cycle his packs and balance them before assembling the final pack. All my packs have been verified. I will bulk charge and balance every 20-30 cycles "if needed".

He is using a Modded Dell Server Power Supply 12v 57A. Im using one on my I charger 306b @ 600w input on the charger and 500w output to the batteries and since im charging at 30A and he will be charging at 20A I know it will be perfectly fine for his application.

If i parallel charge all my packs i have a 16.8v 120AH battery. As long as the temps stay cool on the charger im good to go if the charger overheats it has a fall back where it drops the current 25% to keep the charger cool.
