Ampere-hour (Ah) capacity: Higher Ah capacity provides longer range and more power
Ampere-hour (Ah) capacity is a critical factor in determining the range and performance of an electric skateboard. A higher Ah capacity battery provides a longer range and more power for acceleration and speed.
Ah capacity, or Ampere-hour, refers to the amount of energy charge in a battery that enables one ampere of current to flow for one hour. In other words, it indicates how much amperage a battery can provide in an hour. This metric is essential for understanding the capacity of an energy storage device, such as a rechargeable battery.
A higher Ah capacity means that the battery can deliver more current, resulting in increased power output. For example, a 10 Ah battery can provide 1 ampere for 10 hours, 2 amperes for 5 hours, and so on. Similarly, a 5 Ah battery can theoretically provide a constant draw of 5 amps for 60 minutes before draining, assuming ideal conditions such as optimal temperature and no vibration.
The Ah capacity also impacts the longevity of the battery. A higher Ah capacity allows you to power more devices for an extended period, reducing the strain on the battery components. This reduced workload can extend the lifespan of the battery itself.
It is important to note that the Ah capacity of electric skateboard batteries can vary depending on the model and brand. Therefore, it is recommended to refer to the manufacturer's specifications for the specific amp capacity of a particular electric skateboard model.

Voltage: Impacts torque and efficiency. Industry standard is 36V
The voltage of an electric skateboard's battery impacts its torque and efficiency. Voltage refers to the torque or turning force that a board can produce. It also improves the efficiency of the battery and, consequently, the range of the skateboard. The industry standard for voltage in electric skateboards is 36V.
If the voltage is too low, the board will not have sufficient torque, and the skateboard will struggle to move. Conversely, if the voltage is too high, the motor or ESC (electronic speed control) may not be able to handle the excess power, leading to potential damage or reduced performance. Therefore, it is crucial to maintain the voltage within an optimal range to ensure adequate torque and efficient operation.
The voltage of an electric skateboard's battery is closely related to its ampere-hour (Ah) capacity. Ampere-hours indicate the total charge a battery can hold, influencing the range and performance of the skateboard. Batteries with higher Ah ratings generally provide a longer range and more power for acceleration and higher top speeds. However, it is worth noting that the specific number of ampere-hours per battery can vary depending on the model and brand of the electric skateboard.
Different types of batteries, such as LiPo (Lithium Polymer) and Li-ion (Lithium-ion), commonly used in electric skateboards, have varying voltage requirements and characteristics. LiPo batteries, popular among hobbyists, tend to have lower voltage sag, but they are less safe and require specific handling to prevent safety hazards. On the other hand, Li-ion batteries are more common in commercial boards due to their safety and convenience, despite exhibiting more voltage sag.
To maintain optimal performance and prolong battery life, it is recommended to follow proper charging practices. Slower charging methods tend to preserve battery health better, although they may not significantly impact the performance of the skateboard in the short term. Additionally, it is advisable to avoid discharging the battery to 0% frequently and to store the skateboard with a suitable amount of charge when not in use.

Ampere: Affects top speed
The number of amps per battery in an electric skateboard varies depending on the model and brand. The ampere-hour (Ah) capacity of the battery affects the skateboard's range and performance. Generally, batteries with higher Ah capacity provide a longer range and more power for acceleration and speed.
Ampere (A) is the current that a battery can give, and it affects the top speed of an electric skateboard. A higher Ah capacity means that the battery can provide a higher current, resulting in increased speed. Most electric skateboards require their batteries to have a continuous discharge current of at least 30A to avoid overheating.
The quality of the battery also plays a crucial role in the skateboard's performance. Different battery cells have varying performance characteristics, and it can be challenging for non-experts to determine which battery is better. The voltage of the battery, measured in volts (V), also influences the skateboard's overall power delivery. Higher voltage batteries can deliver more power to the motor, resulting in faster acceleration and higher top speeds.
In addition to the battery, other factors such as the motor power, rider weight, terrain, and riding conditions can significantly impact the top speed of an electric skateboard. The interplay between these factors determines the overall riding experience, including speed, acceleration, and stability.

Continuous discharge current: Batteries should be able to provide this without overheating
Electric skateboards are powered by their batteries, so it is crucial for riders to understand the specifications of their batteries to ensure optimal performance, range, weight, cost, and safety. One of the key specifications to consider is the continuous discharge current, which refers to the number of amperes (or amps) that a battery can provide continuously without overheating. This is an important factor as it can impact the top speed of the electric skateboard and prevent overheating or explosion.
Most electric skateboards require batteries that can provide a minimum of 30 amps (A) of continuous discharge current. However, the specific number of amps per battery can vary depending on the model and brand of the electric skateboard. Therefore, it is recommended to refer to the manufacturer's specifications for the particular amp capacity of a given electric skateboard model.
The continuous discharge current is influenced by the type of battery used. Li-Ion (Lithium-Ion) batteries, for instance, have an electronic controller that regulates power and discharge flow to prevent overheating or explosion. In contrast, Li-Po (Lithium Polymer) batteries are cheaper and have less voltage sag, but they are less safe and more susceptible to starting fires if not handled properly. As a result, Li-Ion batteries are more commonly used in commercial boards, while Li-Po batteries are favoured by hobbyists.
To ensure the safety and longevity of electric skateboard batteries, proper maintenance and handling are essential. This includes charging batteries correctly, following recommended settings, and avoiding overcharging or discharging. Additionally, it is important to monitor batteries during charging for any excessive heat buildup and to replace damaged or swollen batteries promptly to mitigate overheating risks. By understanding the continuous discharge current specifications and practising proper battery care, riders can maximise the performance and safety of their electric skateboards.

Battery type: Li-ion is common, LiPo is cheaper but less safe
Electric skateboard batteries typically range in ampere-hour (Ah) capacity, with the specific number of amps depending on the model and brand. Higher Ah capacity batteries generally provide a longer range and more power.
Li-ion (Lithium-ion) batteries are the most common type of battery used in commercial electric skateboards. They have a longer lifecycle, are easier to handle, and are safer than other options. They are also weaker than LiPo batteries. The 18650 cells and 26650 cells sometimes seen in battery conversations are the types of cells inside a Li-Ion pack, with 18650 being the most common.
LiPo (Lithium Polymer) batteries, on the other hand, are more popular among hobbyists. They are cheaper, have less voltage sag, and have better gravimetric and economic densities (are lightweight and less money per Wh). However, they have significant downsides that limit their use in commercial boards. LiPo batteries are less safe and could start a fire if not handled properly, posing a liability risk for companies. They also require users to drain the battery to a specific charge for storage, and they have a shorter life cycle compared to Li-ion batteries.
In terms of performance, Li-ion batteries have approximately three times the lost energy and voltage drop of LiPo batteries. Li-ion batteries also win on volumetric density, as their cell structure allows them to be shaped to any form factor for almost any integration. However, LiPo batteries have the advantage of being cheaper.
