Electric Scooter Battery - Internal And External

How to choose your electric scooter battery?

The battery of an electric scooter is an element which allows it to operate. In fact, it is this which provides the energy necessary for the electric motor to propel the scooter and allow it to move.

Without an adequate battery, the electric scooter cannot function and loses its main characteristic: the electric assistance which facilitates movement. 

Internal batteries are often more aesthetic and offer better weight distribution of the scooter. It is important to ensure the quality of the battery of your electric scooter to guarantee good autonomy and satisfactory battery life.

What is an external battery for an electric scooter used for?

An external battery for an electric scooter is an optional battery that is used to add additional autonomy to your machine.

Indeed, you will then have understood, you will then be able to add the basic autonomy of the internal battery with the autonomy of your external battery and double the autonomy of your electric scooter.

However, when using an external battery for the first time, be sure to charge your electric scooter to 100% and your external battery to 100% to avoid all forms of malfunction.

But still, who says doubled autonomy, says doubled 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 recharged, you will be able to enjoy your electric scooter twice as much!

• What are the different types of electric scooter batteries?

The Main Batteries

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

But still, for information purposes, electric scooter manufacturers manufacture lead batteries allowing for greater speed, without losing autonomy. However, they are no longer used because their main disadvantage was the weight which was more than 3 or even 4 times heavier than the lythium one.

External Batteries

An additional battery connected to the main battery for: 

• Increase the autonomy of your electric scooter. This way, you combine the amps of your two batteries and benefit from more autonomy.

• Power an auxiliary circuit.

You can use an external battery to power additional circuits on your scooter such as additional lights which will provide additional lighting during your nighttime outings. 

Custom Batteries

A custom battery for: 

• Reincrease the lifespan of your electric scooter. This way, you combine the amps of your two batteries and benefit from more autonomy.

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

A battery manufactured with the criteria of your choice:

• The voltage 

• The amperage 

• The dimensions 

Ideal for replacing a battery that is no longer for sale or for housing 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 personalize your electrical machine > by customizing it.  

A defective battery 

An essential element in the operation of electric scooters, the battery is not indestructible. 

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

We recommend that you first check whether your dashboard (display) and your battery are in working order. If this is the case, look at the controller connections instead.

The most asked questions about electric scooter batteries

Pour les utilisateurs qui souhaitent en savoir plus sur cet élément essentiel de leur trottinette électrique, nous vous proposons ce guide qui répond aux questions les plus fréquemment posées.

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

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

How does a battery work?

There are two categories 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 operate. 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's a climb that's too steep or because your scooter's battery is dead, there's always a chance that you'll push your scooter.

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

Logically, the heavier the electric scooter, the more difficult it is for you to push it. When choosing a scooter, you should carefully consider 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 purchasing an electric scooter, the goal is not to push it with your feet, but rather to move forward effortlessly. Here's 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 the electric scooter battery. If the voltage of your scooter is 48V, the nominal voltage of the battery will also be 48V.

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

Cut-off voltage

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

Thus, in order to protect everything, the electric scooter batteries turn off. You guessed it, it’s time for you to recharge the battery.

Amperage

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

Manufacturer Number

It corresponds to the unique number that the manufacturer gives to a category of part. If the manufacturer manufactures 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 a look at the 36 batteries manufactured. These 36 pieces will each have their own serial number.

Fusible

This safety device ensures the integrity of the power circuit. It protects the batteries by cutting off the electrical 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 system (Battery Management System) is the safety device that protects batteries from overvoltages, under voltage and overcurrent. If there is a 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, these 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 connection between the cables. It is linked to the charging portwith which it must be compatible.

Charging port

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

Heat Shrink Tubing

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 level of battery protection against water and dust. 

This index consists of two parts: 

1. Two letters: IP for protection rating

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

How do you know if an electric scooter battery is dead?

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

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

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

• What are the causes of a battery malfunction?

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

• Shocks, which can damage the components inside.

• Bare or cut wires.

• Oxidation.

• Water infiltration: check using the PHMETER, a colored patch that changes from white to red if there is water inside the controller.

• An overcurrent or a short circuit.

• BMS faulty.

• Soldered battery cells

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

• What advice should you use to properly maintain your battery?

• Prefer original batteries.
  This has been specially designed to suit the power circuit of your electric scooter. 

• Choose your battery according to your journey using the range announced by the manufacturer.

• Take the liberty of customizing your pieces only if you are an expert on the subject. In which case you risk wearing out your battery prematurely.

• Shunting, which consists of soldering the components of your controller in order to increase performance, is also not recommended. Your battery may not be able to keep up. The shunt will definitely result in the loss of your warranty.

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

• La Customisation 

If you are looking for thrills, know that it is possible to juggle the various components of your electric machine. By equipping it, for example, with the battery of another electric scooter in order to increase its performance, speed or autonomy.

Do not hesitate to call 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 guarantee the efficiency of your vehicle. You thus avoid early malfunctions due to 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 question of the battery is essential. Two options are available to users: The internal battery and the external battery.

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

external batteries, for their part, are rechargeable via dedicated terminals and are often easier to replace if necessary. They can also offer fast charging and can be used as spare batteries to extend battery life.

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

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

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