Use of Different Mah Batteries
 

Hey guys, need your advice. Using a Power Expander Comp 12 Plus. Are there any problems with me connecting a 2500mah 6.6v battery to one battery terminal of the SmartFly unit and a 5000mah 6.6v battery to the other battery terminal on the SmartFly? This was suggested by a close friend, kind of want to see what others think of the idea. Will use the setup in a scale model with 11 servos. Many thanks. Chic
