Hey Guys, I got two batteries that came in with the M5. The first one charged perfectly and the battery indicators were working fine. When I attached my second battery, I keep getting the 4S blinking red light? (check image attached) What am I doing wrong here since the first one worked perfectly. I read somewhere if the voltage drops below 3amp the battery is dead. But this is the first charge out of the box. Also, is this covered under freefly warranty terms?
