Note: This item is now discontinued. We suggest the Nanotech 160mah battery - Link
These Nano-Tech batteries with JST connectors are widely used as replacements for the standard batteries supplied with RTF planes such as E-flite MCX, MCX2, MSR and many more. They offer better performance and longevity over cheaper cells on the market. Many users report longer battery life, and more power while using these batteries and they also hold their output voltage slightly longer before starting to drop off.

Their real advantage is higher discharge for weight density. These batteries use  a LiCo nano technology substrate complex which makes for a smooth power transfer. This is achieved due to their very efficient oxidation / reduction process which allows the battery to operate with less internal impedance. The power density of these batteries reaches 7.5 kw/kg.
