EC5 connector plug

This plug serves multiple purposes. Its original intention was to indicate the battery's status through a color-coded system: green signifying full charge, red indicating emptiness, and yellow representing stored energy. However, I soon discovered it performed additional tasks. Firstly, it prevents accidental shortcuts that could damage the battery. Secondly, it safeguards the female connector from potential harm if something heavy is dropped onto it. What sets this design apart from others is its ability to fit seamlessly with any size of blue cover used for the female connector. As shown in the accompanying picture, this innovative plug provides a secure and reliable connection regardless of the cover's dimensions.
