Another battery question

Browsing DX I found this:-

Replacement 22.2V 25C 3300mAh Lithium Battery Pack for R/C Helicopter - Free Shipping - DealExtreme

It's described as a 22.2V 25C 3300mAh Lithium Battery Pack but I'm still very shaky on Ah and mAh - how many of these would I need to make a 44V pack with a reasonable Ah output ? I see it has a wiring loom for a balancer.

There's a few people using rc lipo on the forum.

The above link is one with a buy list should you go down the lipo route.

Firstly - I wouldn't buy lipo batteries from dealextreme and it's more expensive than a 6s5000mah pack from hobbyking ($44ish for Zippy or Turnigy brands - both much better rep than anything from deal extreme) but for 3300mah packs you'd need 6 packs to get 9.9Ah @ 44.4v (2s3p).

Secondly - agree with scottyf - see the list in the other thread - I've also posted on my build thread http://www.pedelecs.co.uk/forum/electric-bicycles/9442-new-build.html

Oh and no need to be shaky on Ah vs mAh - there are 1000 mAh to 1 Ah.
