I ordered a replacement battery for my CP 2 [link]http://www.xheli.com/ek1-0180.html[/link]. They sent me this battery instead [link]http://www.xheli.com/10b11-111v15c1000mah-lithium-polymer-battery-for-rc-helicopter-and-airplane.html[/link]. Did I get a battery of equal or better quality? Thanks in advance.

I'd say you made out better as the Exceed battery has a balance connector and the ESky does not

Actually the stock esky battery does have a balace connector even though it doesn't show in the picture.

if you need 11.1v 1000mah 10c esky stock for a very cheap price, let me know.. I'll tell you when my HBK2 stock motor goes off, then I'll sell you 2 batteries for 15 bux + shipping.
BTW, my motor is starting to twitch while hovering, so I think it'll be not too far.
