All three of my batteries have the dreaded crack near the lights on the front face of the battery casing. Does anyone know if just the case can be replaced and if so, where you can buy the case?
The cracks near the lights are no big deal. They are caused by the pressure of the battery latch springs on the inside of the front cover. Unless the cracks got so bad that some of the plastic broke away and let the spring end come through, which has never happened in my experience, you can just ignore the cracks and keep on flying.
