Hi there,
i'm not familair with the BC6, but a friend of mine is using the Hyperion. I don't know about your country but in Europe it's selled under several brandnames. It's a great charger, but you have to buy a seperate balancer as mrasmm already mentioned.

If it's allowed to make a suggestion: I use a Electrify Triton2 charger, this charger also needs a separate balancer. I love this charger, it's capable for charging / discharging all kinds of battery's: Pb, Nicad, Nimh, and Lipo's. It can cycle your battery's up to 10 times !

Here's a link for specs and productinfo at [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXMAJ0&P=ML]Tower[/link]

Just my two cents [8D]
