Xiaomi Scooter Additional Battery – Extend your range up to 4x and travel 100 kilometers on a single charge!

Xiaomi electric scooters have revolutionized the way we move around cities. They are lightweight, convenient, and eco-friendly, but their range often leaves much to be desired. That’s why we offer a comprehensive solution – a powerbank for your Xiaomi scooter that significantly extends the distance you can travel on a single charge.

* The stated range of the scooter is real but indicative – ultimately the range depends on many factors, such as weight of the user, speed and driving style, air temperature, type of surface, etc.

Up to 1000 charging cycles

In our external batteries, we use only proven and brand-new SAMSUNG cells, which guarantee up to 1000 charging cycles.

We do not use recycled cells, which is common practice in this industry, and which are have shorter life span. Longer battery life means not only peace of mind and greater range, but also care for the natural environment.

Simple battery assembly

After the purchase, you will receive a message from us with detailed assembly instructions, and in case of any difficulties, our technicians will be happy to answer any questions. To successfully use the external battery, you need to make a change to the software of the scooter.

Don’t worry, it doesn’t require any specialist knowledge, our manual is more than enough.

Effortless e-scooter charging

Charging takes place as before – via a standard charger plugged into the scooter charging socket.

Batteries are charged simultaneously.

Highest quality from the leading European manufacturer

We are a Poland-based company that produces additional batteries for the most popular models of city scooters.

Before shipment, each product is subject to strict quality control. We create solutions that we use every day.

 

In the latest models of Xiaomi and Ninebot G30 Max scooters, firmware updates have been introduced that make it difficult for users to independently modify the software, which is necessary for the proper functioning of an additional battery.

How to check if your scooter is eligible to work with an Additional Battery and prepare it for installation:

  1. Download the ScooterHacking Utility app on an Android device from the Play Store: https://play.google.com/store/apps/details?id=sh.cfw.utility or from the official website: https://utility.cfw.sh/
  2. Open the app and connect to the scooter. Some scooters may require pressing the on/off button for authorization.
  3. If the message “Restricted DRV/BLE firmware detected” appears, click “YES” or next to it to close the message.
  4. In the “FLASH” tab, select “INSTALL/UPDATE SHFW.”
  5. A gray message will appear with the name of the firmware tailored to your scooter (e.g., “Regular-Base170-v3.9.1”); select it.
  6. Click “START FLASH.”
  7. After about 30 seconds, the app will finish uploading the modified firmware.
  8. If the message “Flashing failed, Reason: Data format error” appears, you can try “ATTEMPT DRV DOWNGRADE.”
  9. Click “YES.”
  10. If the process succeeds, select “INSTALL/UPDATE SHFW” again and click “START FLASH.”
  11. After about 30 seconds, the app will complete uploading the modified firmware.
    If the process is successful – congratulations! Your scooter does not require a display replacement and is ready to work with an additional battery. Simply connect it to enjoy a greater range. However, if a notification about locked DRV or BLE appears, installing an unlocked display will be necessary.

Frequently asked questions

1. What is an additional battery and how does it work?
An additional battery is an external power pack that you connect to your Xiaomi scooter to extend its range. It works in parallel with the built-in battery – both charge simultaneously and power the scooter together, allowing you to ride further on a single charge.

2. Which Xiaomi scooter models support this battery?
Our additional battery is compatible with the Xiaomi Mi Electric Scooter M365, Pro, Essential, 1S, Pro 2, and Mi 3 models. If you have a different model, contact us, and we’ll check if we can assist you!

3. How much will the range of my scooter increase?
It depends on the battery capacity you choose. For example, the M size (10 Ah) adds about 24 km, while the XL size (20 Ah) can extend the range by up to 47 km. Keep in mind that the actual range also depends on your weight, riding style, and terrain.

4. Is installing the battery difficult?
No, installation is simple, and you can do it yourself. We provide a detailed manual, and the kit includes everything you need, like a Torx screwdriver. If you prefer, you can send your scooter to us, and we’ll install it for you.

5. Will the battery affect the scooter’s speed?
The battery itself doesn’t increase the maximum speed, but with greater capacity, the scooter maintains full power for longer and accelerates faster, especially when the charge level is low.

6. How do I charge a scooter with an additional battery?
Nothing changes – you use the standard charger plugged into the scooter’s port. Both batteries (built-in and additional) charge together, and the charger will show a green light when they’re full.

7. Is the battery safe and durable?
Yes, we use only new cells from manufacturers like Samsung and LG, which last up to 1,000 charging cycles. That’s much more than cheap recycled batteries. Plus, every battery undergoes quality control before shipping.

8. Can I fold the scooter after installing the battery?
Yes, the battery is mounted in a handlebar bag or near the deck, so folding the scooter remains possible and convenient.

9. Does installing the battery void the scooter’s warranty?
Theoretically, any modification could affect the warranty, but in practice, it depends on Xiaomi’s service policy. If you’re concerned, contact us – we’ll advise you on how to do it safely.

10. What’s included with the battery?
You’ll get: the battery in your chosen capacity, a waterproof Wild Man bag with the City Lion logo, a spare rubber cap, mounting brackets for stability, a Torx screwdriver, and an installation manual.

11. Do I need special software for the scooter?
Yes, Xiaomi scooters require a software modification for the battery to work properly. It’s simple – you’ll need an Android phone and an app we mention in the manual. There’s no equivalent for iOS yet. In some cases, you might need to replace the display with an unlocked one.

12. What should I do if I have a problem with installation or the battery?
Write to us at https://citylion.pl/kontakt. Our technicians will help you resolve any issue.

13. How long does shipping take?
We produce the battery in 7 business days, and delivery in Poland takes an additional day. To other EU countries, it’s 3 to 5 business days.

14. Is the battery waterproof?
The bag housing the battery is highly splash-resistant, offering good protection against rain. However, we don’t recommend riding in heavy downpours without extra protection.

15. Why choose a City Lion battery?
Because it’s a high-quality Polish product – we make them ourselves in Mazovia using the best components. We offer you greater range, longer lifespan, and support you can always count on.
