Great battery and works well in my corsair 1.2mm from Eflite. 6 minute battery life with 75% throttle whole flight.

Spektrum lipo batteries may cost more than the average budget battery but is worth every penny. They have out lasted every other brand battery I have. The smart technology takes the guess work out of my RC plane builds.
