Frequently Asked Questions
What is a BMS?
Battery Management System — it monitors each battery cell's voltage, temperature, and current. It protects the battery from overcharging, over-discharging, and overheating.
Can I replace the Ninebot battery?
On some models (Max G30), the battery is removable and replaceable. On others (ES series), it is integrated and replacement is more complex.
