How to remove the speed limit on the Xiaomi electric scooter M365 Pro: 4 proven methods

Xiaomi electric scooter M365 Pro from the factory is limited to a maximum speed of 25 km/h, the standard for most EU countries, which meets safety standards, but many owners want to unleash the full potential of the device, especially if they drive in closed areas or outside the city. In this article, we will discuss legal and illegal ways to remove restrictions, their consequences for warranty, battery and security.

Important: firmware modification or hardware modification will void the Xiaomi warranty and may lead to overheating of the controller, accelerated battery wear or accidents. If you’re a beginner, consider alternatives like buying a factory-unlocked scooter (like Ninebot Max). G30D).

We tested 4 overclocking methods M365 Pro (including firmware via DownG, modification) BMS And we've collected data on their efficiency, cost and risk, and we've got a detailed guide with step-by-step instructions, a comparison table, and answers to frequent questions.

1 Why Xiaomi is limiting the speed of the M365 Pro?

The manufacturer sets the 25 km/h limit for a reason.

• 📜 In the EU and Russia, electric scooters are equated to SIM (means of individual mobility) with a speed limit of up to 25 km / h. Exceeding leads to fines (in Russia - up to 1,500). ₽ under Article 12.29 of the Administrative Code).
• 🔋 Battery safety: At speeds above 30 km/h, the battery discharge current exceeds 15A, which reduces the life of Li-ion cells by 30–40%.
• 🛡️ Protection against overheating: Controller M365 Pro is not designed for long-term operation at high speeds - the risk of combustion MOSFET-transistors.
• 🚑 Insurance: In case of an accident with a modified scooter, the insurance company may refuse payments.

However, some users are willing to take risks for the sake of adrenaline, and if you're determined to lift the restriction, read on.

2. Method 1: Firmware through DownG (the most popular method)

DownG program allows you to change the parameters of the Xiaomi controller M365 Pro via Bluetooth. This is the most affordable way, but it requires caution: the wrong settings can "brick" the scooter.

What you need:

• 📱 Android smartphone (version 7.0)+) or PC with Bluetooth adapter.
• 🔌 Charged scooter (minimum 50% battery).
• 📁 DownG Program (version 3.0)+).
• 🔐 Activation key (free test key valid for 3 days).

Step-by-step:

1. Download and install DownG from the official website. Avoid pirated versions, they may contain viruses.
2. Turn on the scooter and activate Bluetooth. M365 Pro go to Settings → Scooter → Firmware version and write down the current version (e.g. 1.5.4).
3. Connect the scooter to DownG via the Connect menu. Wait for sync (it takes up to 30 seconds).
4. In the Speed Limit section, select the desired speed (maximum 40 km/h, but we recommend no higher than 32 km/h for safety).
5. Press Write and confirm the change. The scooter will reset.

⚠️ Note: After firmware, the scooter may behave unstable at speeds above 30 km / h. We recommend testing acceleration on a flat surface without people nearby.

💡

Before firmware, backup the current settings in DownG (read button) → Save Config. This will help bring back factory settings if something goes wrong.

Method 2: Modification BMS (for advanced users)

The method involves physical intervention of the Battery Management System board (BMS) — It's a battery management system, and it's a way around software constraints, but it requires soldering and electronics.

Pros of the method:

• ⚡ Stable operation without resets (unlike DownG).
• 🔧 It does not depend on firmware updates.
• 📈 You can raise the speed to 35-40 km / h without power drawdowns.

Cons:

• 🔥 Risk of battery damage if soldered improperly.
• 💰 Cost: from 1,500 ₽ For the services of the master (if you do it yourself - only the price of components).
• ⚖️ Total loss of warranty.

What needs to be done:

1. Disassemble the scooter, removing the bottom cover (a cross screwdriver and a plastic mediator will be required).
2. Find a fee BMS — It is located under the battery cells (usually green or blue).
3. Salt the resistor. 10kΩ between B- and P- contacts (exact points depend on the board revision).
4. Get a scooter and check the work.

⚠️ Warning: Bad soldering can cause the battery to short circuit and fire. If you've never soldered, you should see a specialist. BMS The scooter may not display the charge level correctly.

Method 3: Installation of the tuning chip (hardware overclocking)

Hardware chips (such as SpeedBox or TongSheng) TSDZ2) They're connecting to the scooter controller and mimicking the sensor signals, tricking the system, and that's one of the most reliable ways, but it's also the most expensive.

How does the chip work?

1. The chip intercepts the signal from the speed sensor (hall sensor).
2. It distorts the data sent to the controller, causing it to “think” that the scooter is going slower.
3. Allows you to accelerate to 35-50 km / h (depending on the model of the chip).

Comparison of popular chips:

⚠️ Warning: Tuning chips may conflict with firmware updates, such as after Xiaomi update M365 Pro up to version 1.7.0+ Some chips stop working. Check with the seller before you buy.

5. Method 4: Replace the controller with a modified

The most radical method is to replace the regular controller with a custom one (for example, from Minimotors or Votol), which allows not only to remove the speed limit, but also to improve the braking system, increase the power of the engine.

Pros:

• 🚀 Speed up to 50–60 km/h (depending on the controller model).
• 🔄 Ability to fine tune acceleration and recovery.
• 🛠️ Improved protection against overheating.

Cons:

• 💸 Cost: From 8,000 ₽ controller + 3 000 ₽ fitting.
• 🔧 Difficulty: requires a complete disassembly of the scooter and setting the parameters.
• ⚠️ Risk of losing the guarantee on all components.

Where to buy it?

• 🌍 PSWPower (Europe, delivery 2-3 weeks).
• 🇨🇳 AliExpress (search on request Xiaomi) M365 Pro custom controller).
• 🇷🇺 Russian stores: Electric transport RU, ScooterHack.

Replacing the controller is the only way to overclock Xiaomi M365 Pro up to 50+ It's the most expensive and complicated method, requiring experience in electronics.

6 Risks and Consequences of Xiaomi Overclocking M365 Pro

Before you remove the speed limit, assess the possible problems:

• 🔥 Controller overheating: At speeds above 30 km/h, temperature MOSFET-Transistors could exceed 100°C, which leads to their degradation.
• 🔋 Battery life reduction: Current discharge above 20A reduces battery capacity by 2–5% per month.
• 🚨 Legal problems: In Russia, a scooter with speed >25 km/h is equivalent to a moped - you need category M rights and insurance.
• 🛑 Unstable behavior: At high speeds, an emergency motor shutdown may trigger.

How to minimize the risks:

• 🛡️ Install an additional cooling radiator on the controller (cost) ~1 200 ₽).
• 🔄 Calibrate your battery regularly (exhaust and charge once every 3 months).
• 🚴 Use a bicycle helmet and protective equipment.
• 📊 Monitor the temperature through DownG (Diagnostics tab).

⚠️ Warning: If the scooter starts to twitch when accelerating or brakes with jerks, return the factory settings immediately.

7.Opperation alternatives: how to drive faster legally

If you don’t want to take risks but want to increase speed, consider these options:

• 🔄 Firmware update: Some custom firmware (for example, CFW for M365) Optimize engine performance without removing restrictions.
• 🔋 Battery replacement: Installation of a larger battery (e.g., battery, 48V 18Ah opportunistic 36V 12.8Ah) Increases the maximum speed by 5-10%.
• 🚴 Proper landing: Body tilt forward reduces air resistance, which adds 1-2 km/h.
• 🛠️ Lubrication of bearings: Clean and lubricated wheel bearings reduce friction.
