I have an update on my battery problem. after the last post. after the battery failed to hold a charge after I ran it dead I decided to use the factory charger at the recommended time period. after about 8-9 hours the batter got warm. something it never did on the elite. so I kept an eye on it and checked the temp often and after 10 hours , it got fairly warm but not hot . after that charge I have had no issues and the battery is back running a long time on one charge. I charger it when the voltage drops below 10.0 volts . and that is a lot of flying.
