I wanted to know if I can use two cellpro 4s 4amp chargers and one tp1010 charger on my radio shack 25amp ps. I will be charging 3s 2100 packs. If I hook up all three chargers could I do 1c on the packs at the same time or even 2c?
Thanks

its all about the watts
your rs 25 amp outputs 13.8 volts - thats 345 watts
your chargers are ~90%(guessing here) effecient so lets take that out of the watts available leaving you .9 x 345 = 310 watts
Your batteriest at 2c would be 12.6v * 4.2 amps = 53watts
so your 310 avalable divided by your 53 per battery says you can charge 5.8 batteries before maxing out your PS get more chargers!

I charge 2 x 6s 3700 packs at 3.5 amps each on my 25 amp power supply and its still got room to spare. 25amps should be all you'll ever need.

If you have identical LiPos, you can always make a harness to charge them in parallel

pass through 4mm connectors, they are sold at radio shack. They endlessly chain into one another.

the banana plugs I listed plug directly into the power supply and each other. Why would you want to use anything else?

Only because I have no room in back of my power supply to do that, I have everything in an aluminan case and there would not be enough room for 3 sets of bananas plugs stacked together. I just ordered another fma cell pro 4s 4amp charger so I will now have a total of 3 chargers

I have the 4008 mounted in my charge case, and it works very well.
