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: 3S1P / 3 Cell / 11.1VDischarge: 25C Constant / 50C BurstWeight: 333g (including wire, plug & case)Dimensions: 173x49x20mmBalance Plug: JST-XHDischarge Plug: 4mm bullet-connector *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 60degCThickness 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.

The main leads are 1/8 of an inch in diameter which they say is .1250 in decimal,And looking at a wire gauge chart they would follow in between 11 and 12. They don't get warm that much I can tell you. I run them on a quad (I have two and run them one at a time) with 21 amp motors and 30 amp speed controllers x 4 and they don't even get warm after 10 min. of flying.
Bought two of these for a 3s setup on my 47" wingspan foamie pylon with a turnigy 3536 1450kv 8x6E tgs prop. The discharge rate on these gives it huge thrust and instant rpm changes. Will update with amperage draws as soon as my wattmeter arrives

Bought 2 for my 550 quad (not both in parallel but who knows) they seem very well constructed and seem to have power to spare. The only thing is I may have to get a scale and weigh one because (and I very well could be wrong) 333g should be 11.7 oz and they seem a bit heavier. Now my quad will lift em without an issue and it gives it a good COG but it is the heaviest 11.7 oz I think I have ever held...
