More than just a fancy name. TURNIGY nano-tech Lipoly batteries were designed from the ground up with serious performance in mind. 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 a higher discharge rates than a similar density lithium polymer (non nano-tech) batteries. For those that love graphs, it means higher voltage under load, straighter discharge curves and excellent performance. 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: 1300mAh Voltage: 4S1P / 4 Cell / 14.8V Discharge: 45C Constant / 90C Burst Weight: 155g (including wire, plug & case) Dimensions: 73x31x35mm Balance Plug: JST-XH Discharge Plug: XT-60 Advantages over traditional Lipoly 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 1.2mO compared to that of 3mO of a standard Lipoly. ? Greater thermal control, pack usually doesn��t exceed 60degC ? Swelling during heavy load doesn��t exceed 5%, compared to 15% of a normal Lipoly. ? 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.Turnigy
