I like that idea, dji being tight as’ and not including a charger was just another reason not to buy Cs. Also buying products that work and are useful as needed, seems a better bet than buying flymore kit.
Search the forum to see if someone has been able to use both the battery and charging lead at the same time before attempting as you may cause electronic issues. Or just forge ahead and plan for sending in the Crystal Sky for repair if something goes wrong.
If you do it please report back on findings so others who are interested in the same "mod" will know the outcome.
