I have a problem with my Erie-Hexacopter's battery charger.
I got a 4S battery Voltage 14,8V 5200mAh from Erle Robotics and it doesn't seem it can charge my battery. As the same error (E2) keeps appearing on the faulty display.
If someone could tell me if it's a common problem, I've seen similar problems on the forum already for other battery type.
This a link to the video of the connections, error and faulty display : http://jmp.sh/4OcOHty
Thanks a lot for your time,
