I didn’t know where to post this but hopefully someone can answer. I just received a new XG50 today and an extra APS 3 battery. When charging both batteries in the provided charger, the APS 2 is charging fine but the APS 3 will only blink 1 red. I don’t think it’s the charger because when I switch the batteries around the 3 does it still and the 2 is charging. According to the online manual it says a single red light is 0-30% charged or not connected to a power supply. I haven’t tried charging the APS 3 in the scope yet. Thanks
