More than just a fancy name. TURNIGY nano-tech lithium polymer batteries are built with an LiCo 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-tech's are the real deal, delivering unparalleled performance!

You can charge it back to life,but first you need to discharge it down until the two 3.9 cells get down to discharge level.Then charge it at 1/2c.Sometimes this works sometimes it does not.On discharge if you have a balance charger it will only take down the 3.9 cells.Hope this helps.Good luck.JK.
