Power Lithium Battery

To make Qualibike neat and unique ,we created seat-post lithium battery as our power system.Most people won’t recognize it’s an ebike at their first sight.And BMS system is also important .It keeps your battery safe from over-charging,over outlet and high temperature.Also ,BMS manages all the cells to work more efficiently to offer you a longer range.
The seat-post battery is removable so you can either charge it in the bike or separetly in your room.
