More than just a fancy name. TURNIGY nano-tech Lipoly batteries were designed from the ground up with serious performance in mind.
The big benefits of these batteries are they're physically smaller, lighter, higher burst rate, lower internal resistance, and a higher max charge rate. If you are concerned about the size of the battery and you want a pack that can charge fast, then it's worth it to consider the Nano-techs.
Utilising an advanced LiCo nano-technology substrate that allows electrons to pass more freely from anode to cathode with less internal impedance. In short; less voltage sag and higher discharge rates than a similar density lithium polymer (non nano-tech) batteries.
