BMS for Xiaomi Electric Scooter Batteries
This BMS is designed for Xiaomi 36 V batteries with 7.8 Ah capacity.
Why Is My Electric Scooter Battery Not Working?
Does your scooter no longer turn on or have a much shorter range than when it was new?
Common causes of battery malfunctions include:
- Prolonged non-use or improper storage of the battery
- Overloading the scooter or battery
- Short circuit or water damage
- Faulty BMS (Battery Management System)
- Use of an incorrect charger
- Physical damage from a fall
- Cold weather
If your scooter doesn’t turn on, the battery might not be the only issue—other components could be affected, and the battery may have only a partial fault. We offer professional fault diagnosis and battery health testing to identify the actual issue and recommend the most cost-effective solution. Certain batteries can also be refurbished through our authorized partner.
Note: In cold weather, battery range can drop by up to 40 %, resulting in shorter ride times. This is normal, and range will improve as temperatures rise.
How to Store an Electric Scooter Battery in Winter
For a long battery life, keep it active. If you won’t use your scooter for an extended period, charge the battery for at least 15 minutes once a month—discharging isn’t necessary. Li-ion batteries are least stable while charging or when fully charged. For storage, maintain a charge level between 40 % and 60 % capacity. At this level, batteries remain safe and undamaged. If they drop below 20 % charge, long-term capacity loss can occur.
Service Information
For proper replacement of the BMS or any battery inspection, please contact your nearest service center in our network. A regular service check is recommended at least once a year, or immediately if any irregularities appear. This ensures safe riding and a long lifespan for your scooter.
