This Turnigy Nano-Tech 2S 350mAh battery is the perfect battery pack for the FMS range of 1/24th RC crawlers, it can also be used in the 1/18th, but it will give a shorter run time. It is lightweight (only 20g) and is supplied with a Molex 2P connector, so it is compatible with most other small crawlers as well.

More than just a fancy name, Turnigy Nano-Tech high-discharge batteries were designed from the ground up with serious performance in mind. They utilize an advanced LiCo nano-technology substrate that allows electrons to pass more freely from the anode to the cathode with less internal impedance. In short, there is less voltage sag and higher discharge rates than similar-density lithium polymer batteries.
