The batteries provided with the hoverboard are specially manufactured for use with a hoverboard. These are rechargeable batteries, which should not be charged for more than 2 hours at a time. India Hoverboards only gets you certified Li-ion batteries which are very efficient.
A single charge will take you anywhere between 18-20 km, depending on conditions. A few of our product testers also clocked 22.4 km on a single charge. To charge your hoverboard, you should connect the charger to a power socket, and the other end of the charger into the hoverboard, near the battery case. Plugging in the charger causes a red light to be switched on, which turns green when the battery is fully charged.
