going for a 1300 is usually more for "loosing weight"

I have been flying cube LiPOs for awhile now and thought I'd share my experiences.

The point of the LiPO cube seems to be reducing parasitic drag and to put the battery weight around the central axis of an X quad.  You feel a difference at full throttle, especially in the turns, more agility, accuracy, and control.  At one point I had an even mix of strong rectangle and cube Tattu R-Lines of the same 4S/1300mAh/95C rating, every flight session was a comparison, 4 of each. 

I still use the rectangles with my top mounted battery H quads, though I rarely fly them anymore.

Take an X or Stretch X quad, strap the LiPO cube on the bottom, and tilt quad forward 40-80 degrees.  It's out of the airflow with weight closer to the center.  It actually balances out the weight of a gopro session on top nicely as an added bonus.  The centered weight and better agility/accuracy/control makes it easier to get around the turn at any angle and orientation near the top end of the throttle.

LiPOs wear out, how often you fly directly effects how often you buy new batteries.  All of my strong batteries are all cubes these days because I usually fly X quads.  They are the same 4S Tattu R-Lines at 95C.  They perform identically when new.  They both have the metal plates inside and are really tough batteries, but the geometry of the cube also makes the battery stronger than the rectangles, less likely to deform on a "hard landing" (for sure, they can take a hit better than the rectangles, at least under an X quad).

One of the tricks you learn early on is that  least amount of stick/correction is best at full throttle, to the point of changing the line you're flying and correcting gradually later.  Actually I guess that applies to freestyle also, smoother camera footage.  Anyway my point is that when you are tying to use minimal stick movements at full throttle, that increased accuracy/agility/control really makes a difference.

Just my $.02, your mileage may vary.
