Why charging the Xiaomi M365 Pro correctly is not an obvious process
The Xiaomi M365 Pro has become one of the most popular vehicles in the city, but its lithium-ion battery requires a special approach. Many users mistakenly believe that it is enough to plug a charge into the socket and forget until the indicator lights up green, but in practice, bad habits reduce battery capacity by 20-40% in the first year of operation.
In this article, we’ll explore not only the basic rules (often ignored), but also the hidden nuances of how air temperature affects charging speed, why you shouldn’t leave the scooter on charge overnight, and what to do if the battery suddenly stops holding charge.
I'll focus on myths, for example, the popular belief that a scooter should be discharged to zero before charging is a harmful piece of advice that's relevant to 20-year-old nickel batteries, but is detrimental to today's lithium-ion M365 Pro cells.
Specifications of the battery Xiaomi M365 Pro: what you need to know before the first charge
The Xiaomi M365 Pro battery has the following key parameters that directly affect the charging process:
- 🔋 Battery type: Li-ion (lithium-ion), 18,650 cells from LG Samsung (depending on the party)
- 📊 Capacity: 12800 mAh (474 Wh) at 36.7 V
- ⚡ Nominal voltage: 36 V (range of operating voltages: 29–42 V)
- ⏱️ Full charge time: 5-7 hours (using the original RAM)
- 🌡️ Operating temperature range: from -10°C +45°C (but charging is only possible when +5°C +35°C!)
Important: The Battery Management System (BMS) controller in the M365 Pro automatically turns off charging when it reaches 100%, but that doesn’t mean you can leave the scooter connected to the network for days, because even after the RAM is turned off, the battery continues to be under 42V voltage, which creates stress for the cells and accelerates their degradation.
Another critical point is the first charge, and many users make the mistake of getting on the scooter right after they buy it.

Step-by-step: how to charge Xiaomi M365 Pro correctly
Follow this algorithm to maximize battery life:
- Preparation: Make sure the scooter is off (power button held for 2 seconds).The battery temperature should be in the range +10°C...+30°C (optimal room room).
- Connection: Put the charger plug in the scooter connector, then plug the RAM into the socket. Order is important! If you do the opposite, you can spark.
- Process control: The RAM indicator should burn red. After 1-2 hours, check the temperature of the battery case - it should not exceed 40 ° C.
- Completion: When the indicator turns green, disconnect the RAM from the socket first, then from the scooter. Don't use the scooter right away - let the battery cool for 10-15 minutes.
The charging speed depends on the current charge level:
| Charge level when connected | Time to 100% | Battery temperature |
|---|---|---|
| 0–20% | 6-7 hours | Up to +35°C |
| 20–50% | 4-5 hours | Up to +30°C |
| 50–80% | 2-3 hours | Up to +28°C |
| 80–100% | 1-1.5 hours | Up to +25°C |
⚠️ Warning: If the RAM light flashes red or doesn't burn at all, it's a sign of malfunction:
- 🔌 Non-original charger (even if the parameters match)
- 🔋 Damage to the battery (swelling, mechanical defects)
- 🌡️ Temperatures are lower +5°C or higher +35°C
- 💧 Moisture entering the charging connector

Top.-5 Mistakes that kill Xiaomi battery M365 Pro
Even experienced users often make these mistakes without realizing the consequences:
- Charging to the point: Keeping a scooter on charge after reaching 100% is like overeating for a battery. Lithium-ion cells degrade faster at voltages above 4.2 V per cell. The M365 Pro has 10 cells connected in series, so 100% charge = 42 V.
- Storage discharged: If you leave the scooter for long-term storage (for example, in winter) with a charge of less than 30%, the battery can lose up to 50% of capacity in 3 months due to self-discharge and sulfation.
- Use of non-original RAM: Even if the parameters (42V, 1.7A) match, cheap charging does not have protection against overheating and surges, which leads to uneven charge of the cells and shortened service life.
- Charging immediately after driving: If the battery is heated to +40°C or higher, it must be cooled to +25°C before connecting the RAM. Otherwise, the BMS controller may miscalculate the charge level.
- Ignoring calibration: Every 2-3 months, the battery needs to be fully discharged (before the scooter is automatically turned off) and charged to 100%, which synchronizes the BMS data with the actual capacity.
⚠️ Warning: If the scooter travels less than 15 km after charging (with a rider weighing up to 75 kg), this is a sign of battery degradation:
- Check the voltage at the terminals with a multimeter (should be 42 V at 100% charge).
- Examine the battery for swelling (if the case is deformed - do not use a scooter!).
- Try resetting your BMS settings (hold the power button for 10 seconds when the scooter is off).
💡
If the scooter has not been used for a long time, charge it to 60% and store it in a cool place (for example, in the basement at +10 ° C).
How temperature affects battery charging and life
Xiaomi M365 Pro lithium-ion batteries are extremely sensitive to temperature, and studies show that operating at +40°C reduces the life of 30-40% in a year, and charging at -5°C can damage cells without recovery.
Optimal conditions:
- 🌡️ Charging: +10°C...+30°C (perfectly — +20°C...+25°C)
- ❄️ Operation in winter: before -10°C (but charge at lower temperature) +5°C is prohibited!)
- ☀️ Operation in summer: before +40°C. But +35°C is already beginning to accelerate degradation)
What to do in extreme conditions:
| Conditions | Risk | Decision |
|---|---|---|
| Charging at +35°C. | Cell overheating, capacity loss | Refrigerate the battery before charging (not in the refrigerator!) |
| Operation at -15°C | Capacity reduction by 30-50% | Keep the scooter in a warm room, warm the battery |
| Storage at +40°C | Irreversible degradation in 1-2 months | Move to a cool place (such as a garage) |
⚠️ Warning: If the scooter overheats in the sun (the body is hot to the touch), do not charge it immediately. BMS may incorrectly calculate the level of charge, which will lead to undercharge or overcharge of individual cells.

How to extend the life of the battery Xiaomi M365 Pro: expert advice
Following these guidelines, you can increase battery life by 30-50%:
- 🔄 Avoid full discharges: The optimal charge range is 20-80%. Full discharge (0%) and full charge (100%) create maximum load on the cells.
- ⚡ Use only the original RAM: Even if the parameters match, cheap charging doesn't have protection against voltage surges. Xiaomi's original ROM has a chip that stabilizes current.
- 📅 Calibrate. BMS every 2 months: Completely discharge the scooter (before it automatically shuts down) and charge up to 100% without interruption.
- 🏠 Store correctly: If you don't use a scooter for more than a week, charge it up to 40-60% and store it in a cool place (+10°C...+20°C).
- 🚫 Don't leave on overnight charging: Even after reaching 100%, the battery remains energized, which accelerates degradation.Use a timer or smart outlet to automatically shut down.
Extra life hack: If you ride a scooter daily, try to charge it partially but often, like recharging it from 40% to 80% every evening, which reduces the load on the cells and increases the number of charging cycles.
💡
The most harmful scenario for the battery is to charge up to 100% and store it at high temperatures, for example, if you leave the scooter on the balcony in the summer after full charging, the battery can lose up to 10% of capacity in a month.
Frequent charging problems and their solutions
If the Xiaomi M365 Pro scooter is not charging or is acting strangely, use this table:
| Problem. | Possible cause | Decision |
|---|---|---|
| The ZU indicator doesn't burn. | Faulty zoo or socket | Check the socket, try another ZU |
| The indicator flashes red. | Short circuit or incompatible ROI | Use only the original Xiaomi RAM |
| The charge is too long (>8 hours) | Battery or ZU damaged. | Check the voltage with a multimeter (should be 42 V) |
| The scooter does not turn on after charging | BMS protection worked. | Hold the power button for 10 seconds to reset |
| Battery's running out fast. | Cell degradation or BMS malfunction | Check the voltage at the terminals (should be 42 V at 100%) |
If the scooter does not respond to charging at all:
- Check the fuse in the charger (it can burn out when the voltage jumps).
- Check the charging connector on the scooter - perhaps the contacts have oxidized (clean with alcohol).
- Try “wake up” BMS: plug in the RAM, hold the power button for 5 seconds, then turn off and repeat.
⚠️ Warning: If the battery is swelling or deformed, don't try to charge it! This is a sign of thermal acceleration that can lead to fire.
