Of Amps, Volts, and Watts!
I have the Protek 40 power supply which has 4 individually switched 16 amps outputs. (13.8 V, 40 amps, 520 Watts). On each of the four outputs I am plannig to hook up and charge the following batteries:
1. I am planning to use the Hyperion DUO, charging 2 6S 5 Amp LIPO batteries at 4 amps;
2. using a second charger, the Protek DUO again charging 2 6S 5amp LIPO batteres at 4 amps
3. using a single hyperion charger, again putting up one 6S 5amp LIPO at 3 amps
4. and exactly the same as (3) on the 4th output.
By my count, this should put a total load of 22 amps and slightly more than 300 watts on the power supply. Will that work or is that too much?
Any help would be greatly appreciated!

i get the feeling your calculation is incorrect. if your charging 6S at 4amps from an input voltage of 13v then the input to the charger is half the output voltage. I'm no experr but i think that would mean the current draw from your power pack would be more like 8amps.
i'll let the experts answer with more details but thought i'd chip in before something gets warm or worse goes pop.

Those duo chargers, you mean 1 6s battery on each port right?
So to charge one of them at 4 amps, you need approx 100W (25V*4 amps) per battery. So if each output is 16 amps on your PSU you've got 13.8*16 = 220W per port. I think you could do that ok on any one of the ports BUT.. when you add all the other batteries and chargers to all the ports you exceed your total psu wattage. You'll probably have to charge at a bit less amps to keep the total under 520.
