Syma X5C/X5C-1 need to make some modifications to the battery compartment for this battery to fit. It is several millimeters thicker than the stock batteries. All you need to do is snip a piece from the center of the battery holder to give you the extra millimeters you need for the camera/battery cover to fit right. It still holds the stock batteries perfectly and it allows the camera/battery cover to fit properly.Or you could take out the battery door,it will fit better.
