I was wondering is a Li-ion 7.4 would be a good plan? I have tried to use a 6v Nimh and have had very bad luck one flight is all ive got out of it the battery shows 6.6v and the light flashes on the ignition indicating a dead battery. I put a 1/2 amp load on the battery and seen it go as low as 6.4v eather way Ive never managed to get more than a flight out of it No matter what I have to replace this battery with something better than this. Im kind of frustrated with this as ive flown my edge with a DA for days without charging this pack and have never had an issue with it. I would like to have 2 hours run time if not 3 out of a battery pack When i fly i want to fly not worry so far this isnt it.
