Electric Scooter Battery - Internal And External

How to choose your electric scooter battery?

The battery of an electric scooter is an element that allows it to function. Indeed, it is the one that provides the necessary energy to the electric motor to propel the scooter and enable its movement.

Without an adequate battery, the electric scooter cannot operate and loses its main feature: the electric assistance that facilitates movement. 

Internal batteries are often more aesthetic and offer a better weight distribution of the scooter. It is important to ensure the quality of your electric scooter's battery to guarantee good range and a satisfactory battery lifespan.

What is an external battery for electric scooter used for?

An external battery for electric scooter is an optional battery that serves to add extra range to your vehicle.

Indeed, as you will have understood, you can then add the base range of the internal battery with the range of your external battery and double the range of your electric scooter.

However, during the first use of an external battery, make sure to fully charge your electric scooter to 100% and your external battery to 100% to avoid any malfunctions.

But also, doubling the range means doubling the charging time...

Warning: if you want to keep your product in good condition, avoid trying to optimize the charging time of your machine by charging the two batteries separately (this could cause breakdowns and render your scooter out of service overnight)...

Once the 2 batteries are charged, you will be able to enjoy your electric scooter twice as much!

Main Batteries

This is the battery recommended by the manufacturer. It is specially designed to suit the power circuit of your electric scooter.

But also, for information, electric scooter manufacturers used to make lead batteries allowing for higher speed, without losing autonomy. However, they are no longer used because their main drawback was the weight, which was 3 to 4 times heavier than lithium ones.

External Batteries

An additional battery connected to the main battery for: 

• Increase the autonomy of your electric scooter. Thus, you combine the amperes of your two batteries and benefit from more autonomy.

• Power an auxiliary circuit.

You have the option to use an external battery to power auxiliary circuits of your electric scooter such as additional lights that will enhance lighting during your night rides. 

Custom Batteries

A custom battery for: 

• Extend the lifespan of your electric scooter. Thus, you combine the amperes of your two batteries and benefit from more autonomy.

Customize your battery by requesting a battery made according to your needs.

A battery made with the criteria of your choice:

• Voltage 

• Amperage 

• Dimensions 

Ideal for replacing a battery that is no longer sold or to house a second battery in a small space.

• Why change the battery of your electric scooter?

There are several scenarios that may lead you to replace the battery of your electric scooter. The need to change a defective battery or the desire to customize your electric vehicle by personalizing it.  

A defective battery 

An essential component for the operation of electric scooters, the battery is not indestructible. 

If your product or one of its components no longer works, there is a strong chance that the problem comes from the battery.

We recommend that you first check if your dashboard (display or screen) and your battery are functioning properly. If so, then check the controller connections.

For the users who wish to know more about this essential component of their electric scooter, we offer you this guide that answers the most frequently asked questions. about the most frequently asked questions.

• What is the function of the Battery for electric scooter?

The role of the battery is to store the energy of your vehicle. It powers the motor as well as other elements of your electric scooter such as the display or the lighting.

How does a battery work?

There are two categories in the set of electrical parts:

• The power circuit (battery, controller, motor)

• The control circuit (buttons, switch, commodo, accelerator etc.)

The battery acts as the “heart” of your scooter.

It powers it so that the elements that require electrical energy work. Lights, motor, or even horn, all these objects called “servitudes” depend on this essential element for the proper functioning of electric scooters. 

Can you use an electric scooter without a battery?

Whether it is a slope that is too steep or because your scooter's battery is discharged, there is always a chance that you will push your scooter.

Using it as a non-motorized scooter can get you to your destination, but for that, you must choose a scooter based on its weight.

Logically, the heavier the electric scooter, the harder it is for you to push it. When choosing a scooter, you must carefully examine the most important criteria.

If you want to be able to push your scooter, we advise you to choose a lightweight electric scooter. However, when buying an electric scooter, the goal is not to push it with your feet, but rather to move forward effortlessly. This is why you should ask yourself the right questions before buying one.

• What are the characteristics of an electric scooter battery?

Nominal voltage

It corresponds to the number of volts of electric scooter battery. If the voltage of your scooter is 48V, the nominal voltage of the battery will also be 48V.

The manufactured batteries that correspond to the voltage of electric scooters currently on the market are electric scooter batteries 12V, 24V, 33V, 36V, 48V, 52V, 60V, 72V, 80V, and 84V.

Cut-off voltage

This is the lowest voltage threshold tolerated by your BMS (Battery Management System). Below this voltage threshold, the BMS considers that your battery can no longer provide enough energy. 

Thus, in order to protect its system, electric scooter batteries turn off. You guessed it, it is therefore time for you to recharge the battery.

Amperage

It corresponds to the electric current intensity. The higher the amperage, the more autonomy you gain.

Manufacturer numbers

It corresponds to the unique number that the manufacturer gives to a category of part. If they manufacture a series of 36 batteries, these 36 batteries will have the same manufacturer number.

Serial number

The serial number corresponds to the unique number given to each part. Let's take the 36 batteries manufactured. These 36 parts will each have their own serial number.

Fuse

This safety device guarantees the integrity of the power circuit. It protects the batteries by cutting off the electric current in case of overloads or short circuits.

Fuse holder

The fuse holder is designed to house a fuse. It is placed within the electrical circuit. 

BMS

The BMS (Battery Management System) is the safety device that protects the batteries from overvoltage, undervoltage, and overcurrent. In case of risk to your battery, it could intervene to play its role and thus cause the vehicle to stop.

Cells

Cells are the elements that contain electrical energy. Assembled, they form the battery. 

The most used cells on the market are Lithium-ion batteries which are lighter and more efficient.

Connector 

The connector is the element that allows the junction between cables. It is linked to the charging port with which it must be compatible.

Charging port

The charging port is the opening that receives the connector to connect the cables.

Heat Shrink Tubing

The heat shrink tubing is the flexible plastic tube that covers your cables. It protects them from external aggressions such as friction, water, or extreme temperatures. 

Electrical Protection Index 

It defines the battery protection level against water and dust. 

This index is composed of two parts: 

1. Two letters: IP for protection index

2. Two numbers: the first corresponds to protection against solids and the second to protection against liquids. 

How to know if an electric scooter battery is dead?

• When the battery life only lasts a few minutes, it means it is no longer efficient enough to properly power your vehicle.

• When the scooter no longer turns on. This could mean that the battery or the controller is no longer working.

• When the scooter stops for no reason and only starts when charged directly from a power outlet. This failure indicates that the battery has reached the end of its lifespan.

• What are the causes behind a battery malfunction?

Batteries naturally wear out when they reach a certain number of charge and discharge cycles. But other factors can influence their wear:

• Shocks, which can damage the components inside.

• Exposed or cut wires.

• Oxidation.

• Water infiltration: check with the PHMETER, a color tablet that changes from white to red if water is present inside the controller.

• An overcurrent or a short circuit.

• BMS failure.

• Unsoldered battery cells

Only the BMS and the battery cells are covered by the warranty, provided no changes have been made to the original product.

• Choose your battery according to your route using the autonomy announced by the manufacturer.

• Feel free to customize your parts only if you are an expert on the subject. Otherwise, you risk prematurely wearing out your battery.

• Shunting, which involves soldering the components of your controller to increase its performance, is also not recommended. Your battery may not be able to keep up with the pace. Shunting will surely result in the loss of your warranty.

• Remember to recycle your battery at the end of its life to preserve nature and the environment.

• Customization 

If you are looking for strong sensations, know that it is possible to juggle with the various components of your electric vehicle. For example, by equipping it with the battery of another electric scooter to increase its performance, speed, or range.

Do not hesitate to call on a professional who will respect the original components of the power circuit of your electric scooter (motor, controller, and battery). Their operation is linked and must be respected to ensure the efficiency of your vehicle. This way, you avoid early malfunctions caused by one element being too powerful for another.

The internal or external battery: an essential part of an electric scooter

When it comes to choosing an electric scooter, the battery question is crucial. Users have two options: The internal battery and the external battery.

 Internal batteries are integrated into the electric scooter and are rechargeable via a dedicated port. They are often lighter, more portable, and offer better weight distribution of the scooter. However, they are more difficult to replace in case of failure.

External batteries, on the other hand, are rechargeable via dedicated stations and are often easier to replace if needed. They can also offer fast charging and can be used as spare batteries to extend battery life.

There are different types of batteries for electric scooters, such as lead-acid batteries, lithium-ion (Li-ion) batteries, and lithium polymer (LiPo) batteries. Li-ion batteries are the most common because they offer good charge capacity, long lifespan, and do not need to be fully discharged before recharging.

However, Li-ion batteries can overheat and overcharge, which can reduce battery life. It is therefore important to monitor the charge status and charge the battery regularly to avoid complete discharge.

In general, the lifespan of a battery depends on the charge cycle and how it is used and maintained. It is important to use an electric scooter charger and not to fully discharge the battery, as this can also reduce the battery life.
