Ok my hyperion will charge at up to 10amps!
How long will it take to charge a 5s1p A123 pack?
How long will it take to charge a 5s2p A123 pack?

What is "ZIP" Charging?
What chargers will do this?

What charger do you use?

What chargers will work to get fast charging on the two packs i listed?

Since 1p is 2.3Ah, charging at 10A will take about 14 minutes. A 2p will take twice as long to charge, so ~28 minutes.

Despite the assurances from various people, I don't recommend ZIP charging. It can be done safely if you know what you are doing, but there are too many variables to consider (battery charge level, resistance of wire, power supply voltage, etc) to be a viable method for most users . It is basically taking a long piece of ZIP wire (basically 16-18GA lamp cord) and charging A123s directly from a power supply through the wire to your cells. This method relies on the overall resistance of the wire, which varies with length and guage. This resistance limits the charge current. And if you do decide to do this, ONLY DO IT WITH A123 CELLS! A123 cells are more "forgiving" when it comes to charge current.
