HANGTIME HOBBIES great place for info on Eneloop Batteries, I will also add, the Eneloop Battery is better suited for a Transmitter, not a Flight Battery for the Receiver and Servos; I use a Large Capacity Eneloop that I got from Hangtime Hobbies for my Transmitter, best Battery I have used in any Transmitter by far.
