The first key feature of the device is the ability to connect and disconnect an additional battery at any time, regardless of its charge level and the charge level of the internal battery. It is not necessary to align the battery voltage before connecting an additional battery.

The second key feature of the device is that the additional battery can be not only more charged and have higher voltage because of this, also it can even have a higher voltage configuration, for example 12s or 15s, which can significantly increase the scooter speed, up to 45 km/h.
