Every KYMCO Ionex scooter has a fixed internal core battery, as well as a removable one. When charging your removable battery, simply use the core battery to continue riding and pick up the fully-charged removable battery later.
The core battery is recharged by the removable battery. KYMCO Ionex automatically selects the right battery to supply power.
While the world experiments with unattainable charging solutions, Ionex is zero wait.
