Confused about charging rates

[ReV:-O]

Hey guys,

I'm a bit confused about charging rates. I have a very capable Hyperion Duo charger, and a Turnigy 6s 5000mah lipo (this one: http://www.hobbyking.com/hobbyking/s...dProduct=10308)

I've always charged my lipo's normally, like if it's 5000mah, that's what I've charged it as. I think this is 1C charging. To fully charge my lipo, it takes around 1.5 hours, which is rather a long time.

On the lipo itself it says it can be charged up to 5C. I assume that means it will be charged 5 times quicker than charging on 1C. I wouldn't feel comfortable charging it that fast, but I would like to charge it at 2C. How would I go about doing this? Would I just need to put the capacity as 10000mah in the charger?

Bit confused here, any help would be greatly appreciated!

Thanks
