A battery connector is a device that links a battery to an electrical circuit or component. It allows for the transfer of electrical energy from the battery to power various devices, such as smartphones, laptops, and electric vehicles. Battery connectors come in various shapes and sizes, designed to fit specific battery types and applications. These connectors typically consist of metal terminals that create a secure connection, ensuring efficient energy flow. Common types include Molex, Anderson, and XT60 connectors, each serving different purposes based on voltage and current requirements. Proper selection and installation of battery connectors are crucial for safety and performance.
