Default LiPo batteries

hey guys, seeing as I'm planning on buying a E-firestorm flux at some point and it being my first electic I'd just like a little info on LiPo batteries. With the Firestorm flux, what battery is best suited for it? A higher mAH 7.4V LiPo or a slightly lower mAH 11.1v LiPo. I'll be buying the stuff from Australia when I visit and they don't really have a large range of LiPos. Like they have 4500ish mAH 11.1v LiPos going for like $120USD which is a bit out of my price range seeing as I'd need to buy a charger too.

This is basically what I have to choose from. Ideally I'd like to pay under $100AUD for a battery.

Really? I've seen youtube vids of guys running 3s. Just to clarify, 2s is 7.4v and 3s is 11.1v?

It seems you use the 2s LiPos for the Warp 5700kv motor and 3s for something like a 4700kv.

Also, what does it mean when batteries are classed as 20C or 25C. Is that the discharge rate or something? Is higher better? Would something like a "Yeah Racing" 4000mAH 7.4v 25C LiPo suffice?

Yes that battery will put out 100amps..plenty for the flux.And yes thats the discharge rate,You take the mah and multiply the C rating... 4000mah x 25C = 100amps
