Can I use lipo battery instade of 1.5v AA batteries for my flysky t6?

I don't have Flysky T6 but have RCB7x which uses the same battery configuration.
So i guess  you can use 3s lipo. As Flysky T6 uses 8x1.5v AA battery which equals 12v. A 3s lipo will give maximum 12.6v.

Someone here in rcindia has also done it earlier on his Flysky T6. Have a look at it
