More than just a fancy name. TURNIGY nano-tech lithium polymer batteries are built with an LiCo  nano-technology substrate complex greatly improving power transfer making the oxidation/reduction reaction more efficient, this helps electrons pass more freely from anode to cathode with less internal impedance.
In short; less voltage sag and a higher discharge rate than a similar density lithium polymer (non nano-tech) battery.
For those that love graphs, it means a straighter, longer curve. For pilots it spells stronger throttle punches and unreal straight-up performance. Excellent news for 3D pilots!
Unfortunately with other big brands; numbers, ratings and graphs can be fudged. Rest assured, TURNIGY nano-techs are the real deal, delivering unparalleled performance!
