Xiaomi scooters are some of the most popular vehicles in the city, but their longevity depends on how you handle the battery. Incorrect charging can reduce battery life by 30-50%, and in the worst cases, lead to its bloating or even fire. In this article, we will discuss all the steps of proper charging for the models M365, Pro, 1S, 4 Pro and others, taking into account the type of battery, temperature and storage features.
The manufacturer claims that the lithium-ion batteries in Xiaomi scooters are designed for 500-800 full charge cycles, but in practice this number can range from 300 to 1000 – it all depends on the operating conditions. We have collected current recommendations for 2026, including data from official Xiaomi manuals and tips from service centers, so that your scooter lasts longer without losing capacity.
1. Battery types in Xiaomi scooters: what you need to know before charging
All modern Xiaomi models are equipped with lithium-ion (Li-ion) or lithium-polymer (Li-Po) batteries, the difference between them is small for the user, but there are key points:
- 🔋 Capacity: from 7650 mAh (M365) Up to 12800 mAh (Xiaomi Electric Scooter 4 Pro) The higher the capacity, the longer the charging time.
- 🔌 Voltage: standard — 36V (10S configuration, in the case of powerful models — 48V.
- 🔄 Charging cycles: full cycle = Partial charges (e.g. 20% to 80%) are counted as 0.5 cycles.
Important: Xiaomi is using BMS-Battery Management Systems to protect the battery from overcharging, deep discharge and short circuit. BMS will not save from improper operation - for example, if you leave a scooter in the cold or charge with an unoriginal charger.
2. Which charger to use: original vs analogues
The manufacturer strictly recommends using only the original chargers from the kit.
| Model scooter | Voltage (V) | Current (A) | Power (W) | Charging time (h) |
|---|---|---|---|---|
| Xiaomi M365 | 42 | 1.7 | 71.4 | 5-5.5 |
| Xiaomi Pro/Pro 2 | 42 | 1.7 | 71.4 | 6-7 |
| Xiaomi 1S | 42 | 1.7 | 71.4 | 5.5-6 |
| Xiaomi 4 Pro | 54 | 2.0 | 108 | 7-8 |
The use of non-original chargers is fraught with:
- ⚡ Too high current. → Battery overheating and shortened service life.
- ⚡ Unstable tension → elevation.
- ⚡ Lack of protection → Possible recharge (above) 4.2V element).
⚠️ Note: If the original charger is broken, buy a replacement only with a certificate of conformity and parameters identical to the native RAM. Check the marking on the case: the model of the scooter should be indicated.
Signs of a faulty charger:
- 🔌 Heating of the housing over 60°C.
- 🕒 Charging time increased by 30% or more.
- 💥 Extraneous sounds (creaming, squeaking).
3. Step-by-step instruction: how to charge the battery of the Xiaomi scooter
Follow this algorithm to avoid errors:
- Turn off the scooter with the power button (it’s not enough to just stop!).
- Allow the battery to cool for 10-15 minutes if the scooter was used intensively.
- Connect the charger first to the scooter, then to the socket.
- Control the indication: 🟢 Green light on the ZU - charging is completed. 🔴 Red, the process is underway. 🟡 Yellow/Blinking – Error (turn off and check contacts).
Turn off the Zoo.
Whether the scooter is off?|Whether the battery cooled after driving?|Is the original zoo used?|Clean contacts of the charging port?|Indoor temperature 10-25°C?-->
The optimal charging time for most models is 4-7 hours. If the process takes more than 8 hours, this is a sign:
- ⚡ Battery wear (capacity dropped below 60%).
- ⚡ Failure of the Controller or Controller BMS.
- ⚡ Low temperature charge (below) +10°C).
💡
If the scooter is not used for several days, charge it to 40-60% and store it in a cool place (but not in the cold!).Full charge or discharge with long downtime accelerates battery degradation.
4.The optimal charge level: myths and reality
Many users believe that the battery scooter need to discharge "to zero" before charging - this is a harmful myth. Lithium-ion batteries do not have a "memory effect", and deep discharge only harms them.
- 🔋 Daily use: keep the charge within range 20-80%.
- 🔋 Long-term storage (more) 2 week-long): 40-60%.
- 🔋 Emergency: discharge below 10% is acceptable, but not more than 1 time per month.
Why not charge up to 100% every time?
- 📉 At a charge of more than 80%, the voltage on the elements reaches 4.2V, which speeds up their wear.
- 🔥 The risk of overheating increases by 20-30%.
- ⏳ The battery life is reduced by 10-15% in a continuous "full" cycle.
⚠️ Note: If the scooter is stored in winter, once in a while 2 Recharge it for a month. 50-60%, Even if you're not using it, long-term downtime with a charge lower. 20% It can lead to deep discharge and exit. BMS failing.
5.Temperature: Why it's critical
Lithium-ion batteries are extremely sensitive to temperature, the optimal range for charging: +10 °C to +25 °C. What happens when you break:
| Temperature. | Implications for battery | Recommendations |
|---|---|---|
| Lower 0°C | Risk of irreversible damage to elements, loss of capacity up to 20% | Move the scooter to a warm room, let warm up for 2-3 hours |
| 0°C – +10°C | Charging is slower, BMS may fail | Charge at the minimum current (if the ROM supports) |
| +25°C – +35°C | Accelerated degradation, risk of overheating | Use a fan to cool you down. |
| Above +40°C | Critical overheating, risk of fire | Turn off the charging immediately! |
How to check the battery temperature:
- Turn on the scooter and start the Mi Home app (if supported).
- Go to the Devices → Your Scooter → Battery status.
- Alternatively, touch the battery case – it should be warm, but not hot.

6.Scooter Storage: How to Save the Battery in Winter
If you do not use a scooter in the cold season, follow these rules:
- 🏠 Storage area: dry room with temperature +10°C – +20°C (not balcony!).
- 🔋 Charge level: 40-60%. Check once in a while. 1-2 month.
- 🔌 Contacts: Clean the charging port of dirt and moisture.
- 🚫 Prohibited: store near heaters or under direct sunlight.
What can't be done:
- ❌ Leave the scooter in the cold (-10°C and below: electrolyte in the battery may freeze.
- ❌ Store with a fully discharged or charged battery.
- ❌ Use covers made of impermeable materials (condensate risk).
💡
Ideal conditions for winter storage: temperature +15 ° C, charge 50%, humidity below 60%. If these rules are met, the battery will lose no more than 5% of capacity in 3 months of idleness.
7 Common Mistakes and How to Avoid Them
Even power users sometimes make mistakes that shorten the life of the battery.-5 most dangerous:
- Charging overnight: Leaving a scooter connected to the network for more than 12 hours is a risk of overcharging, even with BMS. Modern Xiaomi RAMs turn off automatically, but it is better not to try fate.
- Using a scooter at a charge below 10%: Deep discharge leads to sulfation of the elements. If the indicator shows 0%, do not sit on the scooter - first recharge to 20%.
- Charging immediately after heavy driving: The hot battery charges unevenly. Let cool for 15-20 minutes.
- Storage in disassembled form: If you remove the battery for the winter, store it separately at 40-60% charge, but not longer than 3 months without recharging.
- Ignoring BMS errors: If the scooter does not turn on or the ROM flashes yellow, do not try to "flash" the controller yourself - contact the service.
How to know if the battery is worn out:
- 📉 Significant reduction in mileage (for example, was 30 km, became 15 km on one charge).
- ⏱ Charging time has been reduced to 1-2 (a) the time of the loss of the).
- 🔥 The battery warms up even with a small load.
