  1. It’s less prone to damage because it’s further from the ground.
  2. Compared to the deck’s inside, the stem remains cooler thanks to constant air cooling.


  1. Compared to other placements with stem placement, the battery is thicker and heavier, making it difficult to carry.
  2. Its heavy design shifts the center of gravity forward instead of the center.


Below are the pros and cons of deck battery placement.


  1. Weight distribution is stable and even with a low center of gravity.
  2. With the battery on the deck, the stem has more space, making it narrower and easier to carry around.


  1. With the battery closer to the ground, it’s more prone to damage. Therefore, you must be careful when going down curbs or through puddles.
  2. Due to minimal ventilation in the deck, the battery may overheat. Ensure there are enough heat sinks to mitigate excess heat generation.


Below are the pros and cons of removable batteries.


  1. Removal of batteries hinders theft because the scooter can’t be ridden without the battery present.
  2. It’s easier to charge the battery.
  3. It allows battery extension by simply buying new batteries.


  1. Often removable batteries are stem mounted, making the stem heavier and harder to carry.

How to Properly Charge Your Electric Scooter

Below are the two ways you can charge your electric scooter.

Plugging a Charger Directly Into the Scooter

  1. Locate the charging port on your scooter’s base and plug in the charger. Ensure you have the right charger, as voltage and amp ratings vary.
  2. Plug in the opposite end of the charger to a wall socket. There should be a light to indicate the battery is charging.
  3. Once the battery is fully charged, unplug the charger. Refer to the user’s manual to determine how long the battery should charge because overcharging it might damage it.

Charging a Removable Battery

  1. Find the battery and detach it from the scooter. You might need a screwdriver to remove the panel and access the battery.
  2. Remove any cables or wires attached to the scooter’s terminal. Ensure the scooter is turned off before touching any wires. Also, avoid touching the metal ends of the cables with your bare hands.
  3. Plug the cable terminals into the corresponding plug-in. Often the battery terminals have plastic connectors that click once the charger is securely connected. However, avoid forcing the connectors to connect, as you could break the plastic connectors.
  4. Connect your charger to the battery cable with exposed wires. Your charger is designed with two cable endings with clamps, posts, or ports that create a current once connected to the exposed wires. Connect the red battery cable to the corresponding red battery cable. The same goes for the black cables. Ensure the connection is secure and there are no obstacles between the connection.
  5. Pug in the charger to an electric outlet. Ensure the outlet isn’t wet, damaged, or dirty and that you have the correct voltage charger to avoid damaging the battery. Some chargers can only connect to specific outlets; therefore, ensure you can access the specified outlet.

Making Your Battery Last

  1. Confirm that the charging light is on when you’ve plugged in your battery. If you’ve made the proper connection, there’s a red light with most chargers to indicate the battery is charging. Also, the light will turn green once the battery is fully charged.
  2. Depending on the type of battery on your scooter, allow it 3 to 13 hours to fully charge. Avoid overcharging your battery, as it could damage it. Refer to your user’s manual to determine your battery’s time to fully charge.
  3. Don’t let your scooter’s battery die completely; charge it, as this shortens its lifespan. Modern scooters usually have a red flashing light to indicate your battery is running low. Some scooters may have different light indicators; therefore, refer to your user’s manual for the meaning of different colors.
  4. For the best result, plug in your scooter every time after using it. Charging your scooter’s battery every time after using it ensures the battery chemicals are working okay. For everyday users, it’s a good idea to charge your scooter overnight every day.
  5. If your scooter spends most of its time stored away, fully charge it at least once a month, expanding its lifespan and ensuring it’s up and ready the next time you want to ride it.
  6. If your scooter has no LED lights and your battery appears to not hold a charge, you can use a voltmeter to determine the battery’s voltage and whether it can hold a charge. Connect the negative end to the black test lead and the positive end to the red one. Also, avoid touching the metal ends of the voltmeter probes.

How to Choose the Correct Electric Scooter Charger

It’s important to get the right charger. Otherwise, you risk damaging the battery.

When you’re planning on buying a charger for your scooter, there are a few considerations to remember. 

Operating Limits: 

Your charger’s voltage should match your battery’s voltage. For example, if you have a 48V scooter, you should get a 48V charger.

Electric scooters typically fall under the following categories; 84V, 72V, 60V, 53V, 48V, and 36V.

Amperage is the measure of electric current in amps (amperes).

One amp indicates the electrical charge flowing through a circuit every second.

The higher the amp rating, the more electric charge is sent to your battery and the quicker the battery will charge. Although it can be higher, most chargers have an amp rating of 2A. 

As mentioned earlier, your battery and charger voltage should be the same.

However, the amp rating can be higher or equal to your battery’s. 


Not all chargers are the same because different chargers have different types of connectors.

Therefore, ensuring you get the right charger that matches your battery’s charging port is important.

The most common connector types include:


It’s a circular three-pin connector with a diameter of about 12.44mm with three ports that receive three pongs.

Also, a threaded metal ring holds the charger firmly to the port. 


Similar to the GX 16 in appearance, it’s a three-pin connector with a diameter of 12.5mm. However, it doesn’t have a metal locking ring.

Thanks to the raised plastic isolating the pins and preventing arcing, the M 16 is becoming more and more popular in electric scooters today.


With XLR connectors, you can get either a four or three-pin connector.

The three-pin connector is more popular than the four-pin connectors, which are only found in a few models.


It’s commonly called the bullet connector because of its unusual shape.

Also, it is smaller than the previously mentioned connectors and has two ports.

However, only a few scooters have this kind of connector.

DC Coaxial

It is a barrel-style connector found in a wide range of electrical and various electrical scooters.

It’s made of one central prong.


USB connectors are not common in electrical scooters.

However, some low-power scooters can be charged using a USB connector.

Ideal Configuration

Some of the useful features a good charger should have include:

Charge Rate Control

It allows you to speed up or slow the charging rate by adjusting the amperage.

Often fast chargers with charge settings offer amperage settings from 1A to 6.5A.

The higher the amperage, the quicker your scooter will charge.

Automatic Charge Optimization

If you’re charging your scooter to 100%, your charger automatically reduces the number of amps once the battery reaches 80% while charging, which will optimize the charge cycle and protect the battery.

Input Voltage Control

This feature allows you to set the input voltage according to your location.

For instance, if you’re in the UK, it’s 230V, while in the US, it would be 110V.

Charge Depth Control

It is an important feature that allows you to set when you want the charger to stop charging the battery.

For instance, instead of always charging the battery to 100%, you can set the charger to stop once the battery level hits 90% or 80%.

Battery Size and Type

Using the correct charger for a specific battery type is always recommended. Also, you can use multi-mode chargers to charge your battery to protect and prolong its lifespan.

Fast chargers are suitable for use with large capacity batteries equal to or above 15Ah. If it’s smaller, the charger will put excess pressure on the battery, causing it to overheat.


When choosing a charger for your scooter’s battery, choosing one compatible with it will help prolong your battery’s lifespan and avoid any stressful charging compilations is important.
