We work with the top three hoverboard vendors overseas. This means their batteries are all high quality and tested thoroughly to ensure they are safe. Our batteries are generic, or unbranded however they are certified. In the past, we had utilized both Samsung and LG batteries in the past but found that the quality was almost the same as the generic batteries and almost twice as much expensive. We decided as a team to deliver the best combination of quality and price, thus using the high quality generic batteries.
