Battery replacement help/suggestions

[speedmaniac11m]

I have a colco apache co-axial http://www.xheli.com/new-2009-apache-ah-64-camo-.html comes standard with a 7.4v 1000mAH battery.

I want more flying time out of it.

I was thinking about replacing it with a 7.4V 1300mAH 15C HiPo Battery http://www.xheli.com/10b12-74v15c1300mah-lithium-polymer-battery-for-rc-helicopter-and-airplane.html

Have also considered this battery http://www.xheli.com/abfliba71920.html but i don't have dimensions to compare to.

Have considered a 9.6V but not sure if it will damage my heli.

Whats your guys suggestions?

First off - Lipos are 3.7v per cell -
2 cells = 7.4 volts / 3 cells - 11.1
So buying a 9.6v battery would probably not be a good idea 

If you use a 7.4 volt battery - 1000mah or 1300 it should work as long as it fits in the heli.
