i know you have to be careful with cheap batteries but i brought nimhs off ebay and i have had loads of them now and always been good and give real good performance. their called vapextech (always on ebay for sale) or their site is http://www.vapextech.co.ukwww.vapextech.co.uk.
i have never brought anything else as these have been great and powered my spinner weapon and drive fine. i have the 12v 3700mah that are £20 each, they also do cheaper ones in 7.2 and 8.4 off memory.

a better link for you, just scroll down and you can see the packs i use (yellow ones)
