I have inserted the Micro USB into the controller and charger! i have power on and i know that when the controller is charging the lights flash like the Spark batteries! however they just stay lite! i started with 3 lights, now im down to two so its obviously not charging. do i have a problem with the Brand new cable i bought last week or the controller input??
I am sorry for the trouble with your DJI Spark's battery. Do you have a spare USB cable? Please try to use a different USB cable and see if it will have the same result.
