Batteries for blade 200

[Vanq]

First of all, thanks to everyone who assisted me with my issue on the Honeybee.
Im now after advice for spare batteries for the Blade 200 srx. Where to buy, which type of battery to give a longer fly time. I understand the Turnigy nano-tech 1300mAh 3S 45~90C Lipo Pack is a good battery. Is this okay or too big for the blade? The battery connector looks different but I'm fine soldering a different connector on the helicopter if need be.
Thanks in advance.
