I’m completely new to this, but I’m trying to do a test flight. I assembled everything and I think my battery is fully charged (adapter does still keep indicates charging when plugged in). When I connect the battery, then my pixhawk generates an orange blinking light and shutsdown the propellers. When I checked the logs it’s due to the battery low voltage. But my voltage meter indicator keeps saying 12,5V and around 4.2V per cell. Do I have a bad battery, charger or is my pixhawk broken ? I have no idea which part is broken? Or even if there is a part broken or I missed some config.
