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.
