1. Charging function: The most basic purpose of the lithium battery charger cable is to achieve the charging function. It connects the lithium battery charger with the lithium battery to ensure that the current can be safely and effectively transmitted from the charger to the lithium battery, providing the required power for the lithium battery, thereby extending the service time and life of the lithium battery.

2. Data transmission: In addition to charging functions, some advanced lithium battery charger cables also have data transmission capabilities. This means that when the cable connects the charger and the lithium battery, not only power transmission is possible, but data exchange is also possible. For example, the charger can read the power, voltage, temperature and other information of the lithium battery to better control the charging process and ensure the safety and efficiency of charging.

3. Stability and safety guarantee: The design and material selection of lithium battery charger cables usually take stability and safety into consideration. High-quality cables can resist electromagnetic interference and overheating, effectively preventing safety hazards such as current leakage or short circuits. In addition, some cables are equipped with protection mechanisms, such as over-current protection, over-voltage protection, etc., to further ensure the safety of the charging process.
