Technical Guide: Electric Scooter Batteries

Electric scooters are becoming more and more popular as a convenient, zero-emission way to get around. One of the main things that make electric scooters so appealing is their simplicity – just hop on and go. But what happens when the battery runs out? This guide will teach you everything you need to know about electric scooter batteries so you can keep rolling.

Types of Batteries

The three most common types of batteries used in electric scooters are lead-acid, lithium-ion, and nickel-metal hydride.

Lead-acid batteries are the most common type of battery used in electric scooters. They’re relatively inexpensive, have a high power-to-weight ratio, and are readily available. Lead-acid batteries are also relatively heavy, have a short lifespan, and require frequent maintenance.

Lithium-ion batteries are the second most common type of battery used in electric scooters. They’re lighter than lead-acid batteries and have a longer lifespan. However, lithium-ion batteries are more expensive than lead-acid batteries and can be dangerous if not used properly.

Nickel metal hydride batteries are the third most common type of battery used in electric scooters. They’re similar to lead-acid batteries in terms of power and weight, but they have a longer lifespan and don’t require as much maintenance.

Battery Packs

Most electric scooters use two 12-volt battery packs wired in series to create a 24-volt system. Some higher-end models may use three 12-volt battery packs wired in series to create a 36-volt system.

Voltage and Percentage Remaining

The voltage of an electric scooter battery pack is a good indicator of how much charge is remaining. A fully charged battery pack will have a voltage of 24 volts (for a 24-volt system) or 36 volts (for a 36-volt system). As the battery pack discharges, the voltage will drop. For example, a 24-volt  battery pack that is 50% discharged will have a voltage of 12 volts.

Similarly, the percentage of charge remaining in an electric scooter battery pack can be determined by its voltage. A fully charged battery pack will have a voltage of 100%, while a battery pack that is 50% discharged will have a voltage of 50%.

checking power supply of a battery

To prolong the life of your expensive electric scooter battery, it’s important to keep it charged. Most battery packs can be charged using a standard household outlet, but some higher-end models may require a special charger. 

It’s also important to note that overcharging an electric scooter battery can damage the battery and shorten its lifespan. Therefore, it’s best to only charge the battery pack when it’s below 50% charged.

Voltage Sag

As an electric scooter battery pack discharges, the voltage will drop. This decrease in voltage is known as “voltage sag.” Voltage sag can cause the electric scooter to lose power and decrease in speed. It can also cause the motor to overheat, which can lead to damage.

To avoid voltage sag,  it’s important to keep the battery pack charged. Most battery packs can be charged using a standard household outlet, but some higher-end models may require a special charger.

Capacity Ratings

The capacity of an electric scooter battery is measured in amp-hours (Ah). The higher the Ah rating, the longer the battery will last. For example, a battery with a capacity of 10 Ah will last twice as long as a battery with a capacity of 5 Ah. 

When choosing an electric scooter battery, it’s important to consider the capacity rating. A battery with a higher capacity rating will typically be more expensive, but it will also last longer.

It’s also important to note that the capacity rating of an electric scooter battery is affected by temperature. For example, a battery with a capacity of 10 Ah at 20 degrees Celsius will have a reduced capacity of  9 Ah at 0 degrees Celsius. 

Therefore, it’s important to choose an electric scooter battery with a high capacity rating to ensure that it will last in cold weather.

Battery Brands

There are many different brands of electric scooter batteries on the market, including:

  • LG Chem
  • Samsung 
  • Panasonic 
  • Sanyo 
  • Sony 
  • Bosch 

Each brand has its own advantages and disadvantages. For example, LG Chem batteries are known for their high quality, but they’re also more expensive. Panasonic batteries, on the other hand, are less expensive but they don’t typically last as long.

When choosing an electric scooter battery, it’s important to consider the brand. Some brands, such as LG Chem and Samsung, are more expensive but offer higher quality. Other brands, such as Panasonic and Sanyo,  are less expensive but don’t typically last as long.

It’s also important to note that the brand of the battery can affect the compatibility of the battery with the electric scooter. For example, some brands of batteries may not be compatible with certain models of electric scooters. 

Therefore, it’s important to check the compatibility of the battery with the electric scooter before making a purchase.

Battery Management System

Most electric scooter battery packs come with a battery management system (BMS). The BMS is a computer that monitors the voltage, current, and temperature of the battery pack. 

The BMS is important because it helps to prolong the life of the battery pack. For example, the BMS will automatically shut off the battery pack if the voltage gets too low or the temperature gets too high.

The BMS is also important because it can help to prevent overcharging. For example, if the battery pack is 100% charged, the BMS will automatically shut off the charger to prevent damage.

When choosing an electric scooter, it’s important to make sure that the battery pack has a BMS. The BMS is an important safety feature that can help to prolong the life of the battery pack.

C-Rate

The C-rate is a measure of how fast an electric scooter battery can be charged. The higher the C-rate, the faster the battery can be charged. For example, a battery with a C-rate of 2 can be charged in half the time as a battery with a C-rate of 1.  

When choosing an electric scooter battery, it’s important to consider the C-rate. A higher C-rate will typically mean that the battery can be charged faster, which can be convenient if you’re in a hurry.

However, it’s important to note that the C-rate can also affect the lifespan of the battery. For example, a battery with a high C-rate may have a shorter lifespan than a battery with a low C-rate. 

Therefore, it’s important to choose an electric scooter battery with a C-rate that is appropriate for your needs.

Battery Life

The lifespan of an electric scooter battery is typically measured in cycles. A cycle is defined as one charge and one discharge. For example, if you use 50% of the battery and then recharge it, that counts as one cycle. 

The number of cycles that a battery can endure before it needs to be replaced varies depending on the brand and quality of the battery. For example, a high-quality battery from a reputable brand may be able to withstand 1,000 cycles. 

In contrast, a lower-quality battery from a less reputable brand may only be able to withstand 500 cycles. 

When choosing an electric scooter battery, it’s important to consider the number of cycles that the battery can endure. A higher number of cycles typically means that the battery will last longer. 

However, it’s important to note that the number of cycles can also be affected by how the battery is used. For example, a battery that is regularly discharged to very low levels will typically have a shorter lifespan than a battery that is only discharged to moderate levels. 

Therefore, it’s important to choose an electric scooter battery with a lifespan that is appropriate for your needs.
