I cant remember if it is hyperion or flightpower/thunderpower that uses balance connectors of the same size and pin spacing as the JST XH that hobbyking packs come with, one has a retension clip and the other ha alignment tabs so if you cut the tabs off one it will physically fit in the other and all the pins will make contact, which is a bad thing as the pinouts going to the connectors are different and you will blow the balancing circuit on your charger (or worse). Buy a Hyperion - XH balance lead or board, they are widely available and reasonably priced.

Hobbyking offer some of the best prices in the world and they can only do that by selling in huge volumes but the downside of getting thousands of orders a day is that they often have a backlog and it can easily be a week before they get to yours, if you want cheap and dont mind waiting use Hobbyking, if you want something within a week you will have to use a store in your own locality, but even if they are internet warehouses these stores have to pay import taxes and make a profit so you pay considerably more for the speed. If you want something quick you will have to go to your LHS, they have a high rent to pay on their shop and business rates as well as import taxes and have to pay their friendly and knowledgeable staff, supply the tea/coffee and make a profit so you will pay a lot more than from Hobbyking, but you can get it this afternoon, have a chat, a drink, and get good advice there, which may stop you spending twice and save you money in the long run.
