7 Common Causes of Segway Ninebot not Charging
If your Segway Ninebot isn’t charging, it could be due to a few common issues. Here’s a quick list of the usual suspects:
- Loose or Bad Connections – Sometimes, the charger isn’t plugged in properly, or the connections are just a little loose. A quick re-plug might do the trick!
- Charger Issues – Your charger might not be working correctly. If it’s faulty, it won’t be able to power up your scooter.
- Handlebar Cable Problems – For some models, the cable connecting the handlebar to the scooter might not be connected well, which can mess with the charging process.
- Wiring or Charging Port Troubles – If there’s an issue with the wires or the connection between the charging port and the battery, your scooter won’t charge properly.
- BMS Glitches – The Battery Management System (BMS) is like the brain of your scooter’s battery. If it’s acting up, it can stop the battery from charging.
- Dead or Faulty Battery Cells – Over time, battery cells can wear out or die, which means they won’t hold a charge anymore.
- External Battery Connection Problems – If your scooter has an external battery, it might not be connecting properly with the internal one, causing charging issues.
These are the main things to check when your Segway Ninebot isn’t charging. Don’t worry—we’ll go through each one step by step to help you figure out what’s going on and how to fix it!
Charger Light as a Deductive Factor
Okay, so the most obvious sign that something’s wrong is that your scooter isn’t charging, even after being plugged in for hours.
But here’s a handy clue to help you figure out what’s going on: the charger’s light.
You know that little light on your charger?
It can blink red or green, and those colors actually mean something.
They’re like little hints that can help you figure out what’s causing the problem.
For example:
We’ll use these clues in the next sections to help you understand what’s going on with your scooter and how to fix it.
Troubleshooting & Resolving Charging Problems
1. Checking for Bad Contact:

First things first—let’s make sure everything is plugged in properly. Sometimes, the issue is as simple as a loose connection.
Here’s what to do:
- Replug the Charger – Unplug the charger from both the scooter and the wall outlet, then plug it back in firmly. Make sure it’s snug and secure on both ends.
- Check the Handlebar Cable – If your scooter has a battery inside the stem (the part that connects the handlebars to the base), take a look at the cable connecting the handlebar to the scooter. Make sure it’s properly connected.
Why does this matter?
Well, if the charger or cables aren’t making good contact, the scooter won’t charge properly.
It’s like trying to charge your phone with a loose cable—it just doesn’t work.
The good news? This is an easy fix! A simple reconnection might be all it takes to get your scooter charging again.
2. Verifying Charger Functionality & Understanding Charger Indicator Colors:
Now, let’s check if your charger is doing its job:
- Look at the Charger Light – Plug the charger into the wall but don’t connect it to the scooter yet. If the charger is working, the light should turn green. If the light doesn’t come on at all, the charger might be broken, and you’ll need to contact customer support or get a replacement.
- Try a Different Charger – If you have another charger (maybe one with an external power brick instead of an internal one, or vice versa), give it a try. Sometimes, switching chargers can help you figure out if the problem is with the charger itself.
What if the light is green but the scooter still won’t charge?
This could mean there’s an issue with the battery, the Battery Management System (BMS), or the connections inside the scooter. The charger is working, but something else is stopping the power from getting to the battery.
And if the light and charging behavior don’t match up?
For example, if the light is green but the scooter isn’t charging, or if the light behaves strangely, it could point to a problem with either the charger or the scooter’s charging port.
Don’t worry—we’ll dig deeper into these possibilities in the next steps!
3. Lock Mode and Firmware Updates:
Here’s something you might not have thought about: Lock Mode. If your scooter is in Lock Mode, it might not charge properly.
So, before you plug it in, make sure Lock Mode is turned off.
Also, just like your phone or computer, your scooter’s software (called firmware) needs updates from time to time.
These updates can fix bugs or glitches that might be causing charging problems.
So, check if there’s a firmware update available for your scooter and install it if there is.
In short:
It’s a simple step, but it can make a big difference!
4. Checking Wire Connections between Charging Port & Battery:

If you’re comfortable using a multimeter (a handy tool for checking electrical connections), this step is for you. Sometimes, the problem could be with the wires or connections between the charging port and the battery.
Here’s how to check:
- Set Up the Multimeter – Turn it to the continuity setting (this checks if electricity can flow through the wires).
- Test the Connections – Place one end of the multimeter on the charging port and the other end on the battery. If the multimeter shows a reading, it means the connection is good. If it doesn’t, there might be a break or issue in the wiring.
This test helps you figure out if the problem is with the wires or connections. If the multimeter shows no continuity, it’s time to check the wires more closely or consider getting them repaired.
Don’t worry if this sounds a bit technical—it’s just one way to narrow down the issue!
5. Temperature Considerations & Main Board ( or BMS ) Failure:
Here’s an important tip: Don’t charge your scooter right after riding it.
The battery might still be warm, and charging it while it’s hot can cause problems. Let your scooter cool down for a bit before plugging it in.
The Battery Management System (BMS) works best when the temperature is just right.
What if the charger light stays green, but the scooter isn’t charging?
This could mean there’s an issue with the Main Board (the scooter’s internal control system) or the BMS. In this case, you might need to replace the Main Board with a new one or a working used one to get things back on track.
What if the charging gets stuck at 70%, 80%, or another level?
This is a sign that something’s up with the BMS or the battery cells. You can try using the Ninebot Flasher App to reset the BMS. Think of it like restarting your phone when it’s acting up—it can fix software-related glitches and get your scooter charging properly again.
In short:
These steps can help you tackle some of the trickier charging issues!
6. Software and Physical Battery Cells Inspection:
If your charger’s light has been red for a while, it’s time to take a closer look at the battery itself.
Here’s how you can do that:
- Use the Ninebot App – If you have an Android device, download the “Nine Dash” app and connect it to your scooter. Open the app and check the battery information, especially the “cells” section. This will give you a good idea of how healthy your battery is and if there are any issues.
- Check Individual Cell Voltages – You can also use a tool like M365 Tools to check the voltage of each battery cell. Make sure all the cells have similar voltages. If one or more cells have much lower or higher voltages than the others, it could mean there’s a faulty cell messing up the whole battery.
Why does this matter?
Sometimes, connectivity or software issues can mess with the charging process. The app and tools help you spot these problems. If one cell is acting up, it can drag down the performance of the entire battery.
In short:
This step helps you get to the root of the problem and keep your battery in top shape!

If you’re up for a bit of hands-on work, you can physically check the battery cells yourself. Here’s how:
- Open Up the Scooter – Carefully open the scooter to access the battery. Make sure you know what you’re doing, or ask someone who does!
- Use a Multimeter – Test each battery cell with a multimeter to check for defects. If a cell isn’t holding a charge or looks damaged, it could be the reason your scooter isn’t charging properly.
Why is this important?
Defective cells can mess up the whole battery. If you find a bad cell, replacing it can often solve the charging problem and get your scooter back on the road.
7. Checking External Battery & Its Connection:
If your scooter has an external battery, the problem might be with how it’s connected.
Here’s what to do:
- Make Sure It’s Connected Tightly – Check that the external battery is securely attached to the scooter. A loose connection can stop it from charging properly.
- Inspect the Charging Board and BMS – Take a look at the charging board and the Battery Management System (BMS) to make sure everything is connected tightly and there are no loose wires.
- Test the Internal Battery – Try removing the external battery and plugging the charger directly into the internal battery. If the internal battery charges on its own, the issue is likely with the connection between the external and internal batteries.
Why does this matter?
This is a common issue in some Ninebot scooters. If the connection between the batteries isn’t working right, the scooter won’t charge properly. Fixing this connection can often solve the problem.
In short:

For scooters with external batteries, like the ES or E22 models, having a tight and secure connection is super important.
If the connection isn’t just right, your scooter might not charge properly, no matter how good the battery or charger is.
