Recovery on Xiaomi electric scooter: a complete guide for owners

Introduction: Why is recovery in electric scooters necessary

If you are the owner of an electric scooter Xiaomi M365, Pro 2, 1S Or some other brand, you might have heard the term "recovery" (or regenerative braking), which is one of the key features that affects range, battery wear and even safety. But how does it work? Why some users praise it, and others turn it off at the first opportunity?

In this article, we’ll take Xiaomi’s ESCs from a technical and practical perspective, from the principle of operation to step-by-step configuration instructions, learn how the feature affects real mileage on a single charge (spoiler: not always positive), when to turn it off, and which models support advanced recovery settings through the company’s Mi Home app.

We warn you right away: the information is relevant for firmware 2023-2026. If you have a scooter older than 2020, some settings may not be available - we will also discuss this below.

What is Recovery and How Does It Work?

Regenerative braking (or recovery) is the process by which the kinetic energy generated by braking or descending from a slide is converted back into electrical energy and returned to the battery. Under normal conditions, this energy is simply dissipated as heat (for example, in a disc brake), but in scooters it can be partially "returned".

How does this work in practice? When you release the gas or you press the brake, the scooter engine goes into generator mode. Instead of just slowing the wheels down, it starts to resist rotation, generating current. This current goes into the controller and then into the battery, so you kind of recharge the scooter as you go.

It's important to understand that recovery doesn't produce 100% efficiency. Energy loss is inevitable because of wire resistance, heating of the elements, and other factors. However, even 5 to 15 percent of the energy returned can increase the mileage by 5 to 10 kilometers depending on the style of driving and the terrain.

• 🔋 Energy efficiency: up to 15% energy return under heavy braking.
• 🛡️ Safety: additional resistance to wheels when descending from the slide.
• ⚠️ Battery wear: frequent charge/discharge cycles can shorten the life of Li-ion batteries.
• 📉 Not always profitable: on flat terrain, the effect is minimal.

Pros and cons of recovery on Xiaomi Scooter

Like any technology, recovery has its advantages and disadvantages, and let's go through them in detail so you can make an informed decision whether to leave the function on or turn it off.

Advantages

• ✅ Increased mileage: on scooters with a small battery capacity (for example, M365 280 Wh) recovery can add up to 10-15% range when used actively.
• ✅ Less wear of mechanical brakes: part of the braking force takes over the electric motor, reducing the load on the disc or drum brake.
• ✅ Descent control: on steep slopes, recovery helps to keep speed down without constantly holding the brakes.
• ✅ Green: Less energy is wasted, which is important for eco-oriented users.

Deficiencies

• ❌ Additional battery load: frequent charge/discharge cycles accelerate degradation of Li-ion batteries, especially on scooters older than 2 years.
• ❌ Braking: If the recovery is aggressive, the scooter can suddenly “slow down” when releasing gas, which is dangerous in urban traffic.
• ❌ Reduced maximum speed: on some models (for example, Pro 2) when the recovery is included, the scooter does not accelerate to passport 25-30 km / h.
• ❌ Does not work at low speeds: if you go slower than 5-7 km / h, the recovery is automatically turned off.

⚠️ Note: On Xiaomi scooters with firmware until 2021, recovery can cause the controller to overheat during long descents. If your scooter suddenly starts to twitch or lose power, check the temperature of the body!

How to turn on or off recovery

Recovery management on Xiaomi scooters depends on the model and firmware version. Let's look at all possible ways, from standard to "advanced".

Method 1: Through the button on the steering wheel (for M365, Pro, 1S)

On most models, recovery can be turned on/off with a double press of the power button.

1. Turn on the scooter (one short press).
2. Wait until the speed appears on the display.
3. Twice quickly press the power button.
4. The display will display an icon of the battery with an arrow (recovery is enabled) or a crossed-out battery (disabled).

Method 2: Mi Home (for Pro 2, 4 Pro, 1S)

Newer models support the setup of recovery through a proprietary application.

1. Connect the scooter to the Mi Home via Bluetooth.
2. Go to the Settings section → Recovery.
3. Choose from the following levels: Weak (minimum braking, small charge returns); Medium (balance between efficiency and comfort); Strong (maximum charge returns, but sharp braking).

Save the settings and restart the scooter.

Method 3: Through custom firmware (for advanced)

If you have a modified scooter (for example, a modified firmware, CFW Or ScooterHacking Utility, you can fine-tune recovery via PC:

1. Connect the scooter to the computer by USB (use the ST-Link or USB-TTL adapter).
2. Open a firmware program (such as DownG).
3. Go to the Battery section & KERS Settings.
4. Set up the parameters: KERS Strength – Recovery Force (0–100%). KERS Activation Speed – Activation speed (recommended 7-10 km/h). KERS Battery Voltage Limit – Maximum voltage for recovery (usually 40–41V for 36V batteries).

Save the settings and re-flash the controller.

⚠️ Attention: Incorrect custom firmware settings can disable the controller or battery. If you are not sure, contact a specialist!

💡

On Xiaomi scooters M365 Up to 1.2.5 firmware, recovery may spontaneously turn on after the upgrade. To avoid this, reset to factory settings (hold the power button for 10 seconds).

When Recovery Is Really Good (and When It Is Not)

Recovery is not a universal solution, but it depends on the terrain, the driving style, even the weather, and we'll figure out where it's going to be useful and when it's best to turn it off.

Situations where recovery is beneficial

• 🏔️ Mountainous or hilly terrain: If you drive downhills frequently, recovery can save up to 20% of your charge.
• 🚦 Frequent stops: In urban traffic with constant braking, the function returns some of the energy.
• 🔋 Long trips on the verge of discharge: if the battery is almost dead, recovery can give an additional 2-5 km of mileage.
• 🌧️ Slippery coating: Light electrical braking is safer than sharp mechanical braking.

When is it better to turn off recovery?

• 🛣️ Smooth tracks without descents: on a straight road, the effect is minimal, and the battery receives extra charge cycles.
• ⚡ Battery new or badly worn: Li-ion batteries do not like frequent recharging on low currents.
• 🏎️ Sporty driving style: Recovery limits maximum speed and degrades dynamics.
• ❄️ Frost is lower -10°C: the battery is already operating in stress mode, the additional load will accelerate the degradation.

The Effects of Recovery on the Battery: Truth and Myths

One of the most controversial questions is how recovery affects battery life, so let's get a sense of the physics of the process and separate the facts from the speculation.

Li-ion and Li-pol batteries, which are used in Xiaomi scooters, have a limited number of charge/discharge cycles, usually 500-800 full cycles until a noticeable decrease in capacity. Recovery adds microcycles: every time energy is returned to the battery, a mini charge occurs, which is counted as part of the full cycle.

But it's not all that bad.

• Modern controllers (e.g. Xiaomi Pro 2 and later) optimize the recovery current so as not to overload the battery.
• If the battery is more than 80% charged, the recovery will automatically shut down (to avoid overcharging).
• With the right settings (weak/medium level), the impact on battery life is minimal.

But there's a downside.

• If you drive with a strong recovery constantly on, the battery can lose up to 30% of its capacity in 1-1.5 years (instead of 2-3 years in normal operation).
• In the cold, recovery increases the risk of plate sulfation (especially on worn-out batteries).
• Scooters older than 2019 (for example, M365 first batches) controllers do not always correctly limit the recovery current, which can lead to swelling of elements.

💡

If your scooter is over 2 years old, use only the recovery level "weak" or turn it off completely, which will extend the life of the battery by 30-50%.

Alternatives to recovery: how to save charge without it

If you’ve decided to turn off recovery but want to maximize your mileage, there are a few proven ways to save energy:

• 🛴 Smooth acceleration: pressing the gas increases consumption by 20 to 30 percent.
• 🎛️ Optimal tire pressure: flat tires increase resistance. M365 norm - 2.5-3.0 bar.
• 🚲 Use the pedals: even a slight pushback with the foot at the start saves 5-10% charge.
• 🌡️ Avoid extreme temperatures: when -10°C battery capacity drops on 30%, while +30°C accelerating degradation.
• 🔄 Eco mode: in the Mi Home application, you can limit the maximum speed to 15-20 km / h, which increases the mileage by 15-20%.

Another effective method is regenerative braking without recuperation, which is to drop the gas before stopping, allowing the scooter to slow down naturally, which reduces the load on the mechanical brakes and saves energy without overloading the battery.

If you want maximum mileage, consider installing an additional battery (e.g., Xiaomi External Battery for the first time). M365). This will increase the capacity by 180-300 Wh, adding up to 20-30 km of travel.

Frequent recovery problems and their solutions

Sometimes recovery doesn't work properly: the scooter twitches, the battery doesn't charge, or the function shuts down on its own, and let's look at the typical malfunctions and how to fix them.

If none of these methods worked, the problem could be in the hardware:

• Check the battery status (voltage at the terminals should be 36-42V for 36V models).
• Examine the controller connectors for oxidation or breakage.
• If the scooter is warranty, contact the Xiaomi service center - self-repair will deprive you of warranty.

⚠️ Warning: If after activation of recovery the scooter begins to accelerate independently (without pressing the gas), immediately disconnect it and check the controller.
