The Xiaomi Mi Electric Scooter series has deservedly become the benchmark for urban mobility, but the standard 1S model specs often seem limited to owners. Many enthusiasts are eager to squeeze the most out of their device, wondering how to actually pump the Xiaomi 1S scooter without fatal damage to electronics. The standard speed of 25 km / h and a power reserve of about 30 kilometers are just basic indicators that can be significantly improved.
The modernization process requires a deep understanding of the electric vehicle and a willingness to take on the risks associated with loss of warranty. In this article, we will discuss in detail the software and hardware methods for increasing productivity, as well as assess the feasibility of each step.
Before you start to take action, you need to be clear about the difference between software overclocking and physical replacement of components. Tuning can range from simple flashing to complete replacement of power elements. We will look at each stage so that you can choose the optimal path for your needs.
Programmatic acceleration and change of region
The most affordable and safe way to start the modernization is to change the program restrictions through changing the region in the Mi Home application. By default, for many regions, including the CIS countries and Europe, the software speed lock is set at 25 km / h. By switching the region to China or the United States, you can unlock the engine potential up to 30 km / h.
To do this, you'll need to install the Mi Home app, add a scooter, and change the region in your device settings, but this method doesn't always work, because the controller firmware can be tightly tied to the region when you first connect, and in these cases, you'll need to flash it through a Bluetooth adapter or cable.
💡
Before changing the region, be sure to write down the current settings and take screenshots of the battery status so that in the event of a reset, you can assess the actual wear of the elements.
It's worth considering that software acceleration increases the battery and controller load, and while the 5km/h gain seems small, it has a tangible effect over long distances, safety should remain a priority, especially when driving at night or on rough asphalt.
⚠️ Warning: Changing the region to China may activate voice notifications in Chinese that cannot be disabled by standard methods without further flashing custom software.
Installation of custom firmware
If standard regional change methods fail or are blocked by the manufacturer, custom firmware comes to the rescue. Enthusiasts around the world create modified versions of firmware that remove speed limits, improve recovery, and allow for fine-tuning of the controller settings. One of the most popular is firmware from Darkpaw.
The installation process requires a computer, USB-You connect to the scooter, download the firmware file, and start the update process, and at this point it is critical to ensure a stable connection, because interrupting the data record can lead to the "bricking" of the device.
Risks of custom firmware
Custom firmware often allows you to not only increase the top speed, but also adjust the starting power. This makes acceleration more sharp, which is popular with experienced riders, but can be dangerous for beginners, and it also allows you to turn off the sound signals and change the logic of the indicators.
- 🚀 Removal of speed limit to 35-40 km/h depending on the version.
- 🔋 More accurate calibration of the battery charge indicator.
- 🔇 Ability to turn off irritating sound signals.
- ⚙️ Gas handle sensitivity and recovery adjustment.
After the new firmware has been successfully installed, it is recommended that you run a test run in a safe place, check the brakes and the engine's response to a sharp throttle opening. Electronics are now in a more intense mode, so the first kilometers must pass under close observation.
Hardware tuning: replacement of the controller
When software methods become insufficient, riders move to hardware. The current limit of the Xiaomi 1S controller prevents the motor from reaching its full potential, especially on lifts. Replacing the controller with a more powerful one (for example, from N-controller or Minieco) is a radical step that changes the dynamics of the ride.
The new controller is capable of delivering more current, which ensures a confident start from a standstill and maintains speed on slopes. However, such a replacement often requires over-sweetening of power wires or using special adapters, since the connectors may not match, a task for those who are friends with a soldering iron and a multimeter.
☑️ Ready to replace the controller
If the BMS (battery management system) is not designed for high discharge currents, it can go into defense and turn off the scooter at a sharp start, so before upgrading the controller, the battery unit often has to be upgraded.
A comparison of the standard and customized controller shows a significant difference in performance, and the following is a table illustrating typical differences in performance:
| Characteristics | Staff controller | Tuning controller | Impact on riding |
|---|---|---|---|
| Maximum current | ~15 A | 20-25 A | Best acceleration dynamics |
| Speed support | up to 25-30 km/h | 45 km/h | High cruising speed |
| Work on the rises | Reset speed | Stable traction | Confident overcoming the slides |
| Compatibility | 100% | Needs further development | Complexity of installation |
Modernization of the battery
Increased speed and power inevitably leads to increased power consumption: a regular battery with a capacity of 36V 7.65Ah (275 Wh) when driving at high speed can be short even 15-20 kilometers.
There are two main ways to solve the energy issue: the first is to install an external power bank that connects parallel to the main charging connector or directly to the terminals (via the diode junction); the second, more aesthetically pleasing, but time-consuming method is to replace the internal cells 18650 with elements with higher capacity, for example, Samsung 3500mAh or LG MJ1.
💡
For maximum range it is better to use high-capacity cells (3000-3500 mAh), and for high speed and dynamics, the current output of cells (power cells) is more important.
When you build it yourself or replace it, it's critical to use spot welding, soldering irons heat the lithium cells, destroying their internal structure and reducing their resource. BMS-charge from the old battery to the new, observing the balancing of cells.
Remember, increasing the battery capacity means increasing the weight of the scooter, and if you install a dual-capacity battery, the range will increase proportionally, but it will be much harder to drag it up the stairs, a trade-off that each user evaluates individually.
- 🔋 Increase in range to 60-70 kilometre.
- ⚖️ Increase in total weight of the structure 1.5-2 kilogram.
- 💰 High Cost of Quality Elements.
- 🛠 The complexity of the replacement process requires electronics skills.
Improvement of driving performance and braking system
The pumping of the engine and battery makes no sense if the scooter brakes poorly or is rigidly uneven. The standard brakes, especially the drum brakes at the rear, often require improvement. Installation of more tenacious pads, adjustment of the cables and replacement of brake fluid (if hydraulics are used in modifications) is a mandatory step after increasing speed.
The comfort of the ride depends on the wheels and suspension. Xiaomi 1S has no shock absorbers, so all vibration is transmitted to the rider. Installing pneumatic (inflatable) wheels instead of chamber or using cast wheels with gel-filled (solid tires) radically changes the experience. gel wheels will never penetrate, but they are stiffer and heavier.
Also worth paying attention to bearings: Replacing regular bearings with reinforced versions with metal anthers (for example, 608Z or 608RS) will prolong the life of the chassis. Regular lubrication of bearings reduces friction, which also has a positive effect on maximum speed and coasting.
⚠️ Warning: When installing wider or heavier wheels, make sure they do not touch the wing or frame elements when the scooter is fully loaded and the suspension compressed (if any).
You can also install disc brakes instead of standard brakes if the frame and plug design allows this modification, which will significantly improve braking, which is critical at high speeds, but this modification often requires drilling holes and can be irreversible.
External tuning and protection
After the technical upgrade, you want to improve the appearance. The market for accessories for Xiaomi is huge. Start with protection: installing additional reflectors, bright LED tape on the deck or installing a powerful flashlight on the steering wheel will significantly increase your visibility in the dark.
To protect the electronics from moisture, which is the main enemy of the scooter, it is recommended to waterproof charging ports and deca-wheel joints. The use of silicone sealants and special spray dielectrics helps to survive even heavy rain.
Stylish additions include stickers, custom grips on the steering wheel and a phone holder, some of which add extra footrests for the passenger, although this is not recommended on single-engine versions due to the increased load on the frame and battery. Visual tuning should not interfere with functionality and folding of the mechanism.
To conclude, cleanliness is important: regular washing (without high water pressure!) and lubrication of moving parts will keep the tidy appearance and prolong the life of components. A clean scooter is easier to diagnose for backlashes or cracks.
