OK, this battery gets a "Mike's Thumbs UP"!
I got two of these batteries in yesterday.
$11.17 Authentic ZOP Power 11.1V 1500mAh 20C Li-Polymer Battery at FastTech - Worldwide Free Shipping
The battery is rated 1500mAh and they clock in just shy of it, pretty damn close, a lot closer than many other brands.
While they are rated "1500mAh" they are the
exact same size in every dimension as the Turnigy 1300. Even more curious is that the sticker on the two I got says 40C not 20C.
Actual unaltered measured dimensions are 71mm x 34mm x 23mm, although the wires exiting the head will eat up another mm. You "could" take off the heatshrink, reroute the wires, reinsulate it, and save a lot more room. I think you could get it down 66mm if you tried.
According to the Evolv Escribe Battery Analyzer:
Bat #1 - 15.49 WH
Bat #2 - 16.17 WH
Also do consider that this was the first cycle on both of these batteries, if anything the storage capacity improves after a few cycles.
Turnigy 1300mAh Avg - 14.14
ZOP 1500mAh Avg = 15.83
ZOP was an average of almost
11% more power for the exact same footprint of the Turnigy

The Venom FLY battery (at twice the cost) is the only other tested battery that match this energy density.
Good energy density, at a great price, makes this battery a winner in my book.
