Turnigy Nano-Tech 2200mAh 4S 25C Lipo Pack w/XT60

Specs: Capacity: 2200mAh Voltage: 4S1P / 4 Cell / 14.8V Discharge: 25C Constant / 50C Burst Weight: 219.5g (including wire, plug & case) Dimensions: 103x35x30.8mm Balance Plug: JST-XH Discharge Plug: XT60 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 1.2mO 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 lipo technology.
