The Accu-Cycle Elite WILL charge a futaba Radio with the battery in the radio.. It will not however discharge or cycle your battery. I'm not sure if this is true for every futaba radio ever made, but both of mine (9C and a cheap 4 channel) both have the diode.. My cynical side thinks maybe they do this to keep you from cycling the battery thus forking over another 35 dollars for a new battery after a few years? Who knows, but I have been using my Accucycle for going on 3 years now to charge these radios..

If ya'll need help with the charger let me know what radio/pack you have and I will post settings that will work for the battery.. It's really very simple..
