Serial connection cable for XIAOMI

This cable is used to add voltages to the controller of any electric scooter. This is achieved through a series battery configuration, which consists of adding the voltage of the second battery we want to install to the original battery through our cable.
Important!!
Verify that the controller is prepared to support the addition of the voltages. This cable also serves to add a battery power cutoff switch by adding a jumper connector (not included).
