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!Spec.Capacity: 4000mAhVoltage: 4S1P / 4 Cell / 14.8VDischarge: 25C Constant / 50C BurstWeight: 433g (including wire, plug & case)Dimensions: 173x48x26mmBalance Plug: JST-XHDischarge Plug: 4mm bullet-connector Suited to the following models: Hirobo Lepton EX, HIROBO SDX-EP(4S x 2)* The nano-core technology in lithium ion batteries is the application of nanometer conductive additives. 1) The nanometer conductive additives form ultrastrong electron-conducting networks in the electrodes which can increase electronic conductivity. 2) These additives create a superstrong ability for imbibition in the carrier liquid to supply more ion channels. This improves the ability of ion transmission and ion diffusion. Through improving electronic conductivity and ion transmission, the impedance is reduced and the polarization of high rate discharge decreases greatly.Advantages over traditional Lipo batteries;-Power density reaches 7.5 kw/kg.-Less Voltage sag during high rate discharge, giving more power under load.-Internal impedance can reach as low as 1.2mΩ compared to that of 3mΩ of a standard Lipoly.-Greater thermal control, pack usually doesnt exceed 60degC-Thickness swelling during heavy load doesnt exceed 5%, compared to 15% of a normal Lipoly during heavy load.-Higher capacity during heavy discharge. More than 90% at 100% C rate.-Fast charge capable, up to 15C on some batteries.-Longer Cycle Life, almost double that of standard lipoly technology.

I have been using these for a few months now . They are the best lipos yet . I cant attest to longevity yet but they have far more output then any turnigy or zippy lipo . Voltage at wot drops to 14.4 on a fully charged pack . I have some other packs that drop to 13volts . I also get a minute more of flight time out of these . So far so good . Hope they at least last for a year of flying .

This battery is high quality and good value. I don't have much experience, but I've completed about six charge cycles on the three batteries I bought. After accidentally running one of three batteries down too much, flight club members thought I may have ruined a battery but were supprised to see the battery reach full balance charge of 16.8 volts exactly the same as the other two I own. Much better price than elsewhere. I also see these on sale at the local hobby shop for a lot more money.
