How To Choose The Right 36V Lithium Battery

Spread the love

Since the 1990s, Li-ion batteries have been in existence. You may be curious why you should opt for a 36V Lithium battery instead of other options. However, there are several reasons why they have become a crucial aspect of contemporary life. They have a longer lifespan than other rechargeable batteries, they are safer, and they enable you to use your devices for extended periods without requiring an electrical outlet.

Therefore, it is crucial to consider these factors before purchasing a 36V Lithium battery online or at a nearby store:

Charge Time

When purchasing a 36V Lithium battery, it is essential to ask how long it takes to charge. Running out of power halfway through your ride can be frustrating, so it’s crucial to choose a battery with a fast charging time. Additionally, the battery should come with an indicator, like an LED light, to let you know when it’s fully charged.

What is The Capacity of Your Battery?

The capacity of a 36V Lithium battery refers to the amount of energy it can store, measured in amp hours (Ah). A higher capacity means that the battery will last longer between charges, providing more miles per charge cycle before requiring another recharge. However, other factors can also impact the battery’s performance, such as terrain type which can affect how fast or slow one goes downhill, rider weight which can determine the power needed from the bike at any given moment, and so on.

Size and Weight

At first glance, lithium batteries appear to be an obvious choice for various reasons. They are smaller and lighter compared to lead-acid batteries, making them more manageable to store or attach to your bike. Additionally, they typically have a longer lifespan than lead-acid batteries, but they are also more expensive.

Another factor to consider is the voltage of the battery. Due to their compact size, lithium batteries have higher voltages (36V compared to 12V), making them suitable for electric bikes. However, this makes them less suitable for use in cars or trucks, where higher voltages can be hazardous if mishandled. It is essential to have an experienced mechanic who knows how to handle high-voltage equipment safely.


Voltage refers to the quantity of energy that can be transmitted within a specified duration. An increase in voltage leads to a higher amount of energy that can be conveyed within the same duration. To illustrate, a lithium battery rated at 36V has a higher voltage compared to an 18V lithium battery.

Volts is the unit used to measure the voltage of a battery, and the greater the voltage, the more energy the battery can provide. To illustrate, a lithium battery rated at 36 volts has a higher voltage compared to an 18V lithium battery.


The wattage of a motor determines the extent of work it can perform, and it is quantified in watts. Typically, lithium batteries rated at 36V have a wattage ranging from 250 to 500 watts. When considering an electric scooter or bike, a higher wattage indicates a more robust ride, but it may necessitate more frequent recharging of the battery if its capacity is below 300 watt-hours (Wh).

What does this imply for you? If you seek a means of swift travel in urban areas, with reduced stops and charging duration, then opt for a battery with a high wattage (300Wh or greater). Our Volt Xtreme 300W Electric Scooter Conversion Kit, featuring an 18Ah 36V Li-ion Battery Pack, Charger, and LED Headlight/Taillight Set Bundle, would be a suitable choice.

Type of Battery

Lithium ION Batteries

  • Lithium-ion batteries are the most prevalent type of battery utilized in electric bikes. They are frequently considered the most dependable and efficient battery, but there are some trade-offs to contemplate before selecting one.
  • Compared to other battery types like lead-acid or nickel-metal hydride (NiMH), lithium-ion batteries have a higher energy density, meaning they can store more energy per kilogram or pound. This allows for a longer distance on a single charge if your bike uses this type of battery.
  • However, lithium-ion batteries have a downside in that they are more susceptible to damage caused by overcharging or discharging too quickly, which can occur if the bike is not adequately maintained. Additionally, they are more costly than other alternatives.

Amp Hours (AH) Rating

The ampere-hour (Ah) rating of a battery provides an estimation of its operational duration. A larger Ah rating suggests an extended run time, and it is determined by the battery’s capacity. The Ah rating is computed by multiplying the battery’s voltage by its amperage. For instance, if a lithium-ion battery pack has a capacity of 20Ah and a voltage of 36V, its Ah rating would be 36 x 20 = 720Ah.

Consider These Factors When Purchasing A 36v Lithium Battery

  • When purchasing a lithium battery for your bike, it’s essential to assess its size and weight. A lightweight battery would be preferable to prevent adding unnecessary weight to your vehicle.
  • Prior to deciding on a purchase, examine the voltage and wattage ratings of various batteries. Not all 36V lithium batteries are identical; some may possess higher voltages or wattages, providing more power compared to other models within their class range. This would be beneficial if your e-bike is utilized for commuting purposes.
  • Determine whether you require two distinct 12V batteries or a single large 36V model. This might be a matter of personal preference, as some individuals prefer having separate 12V units, while others are content with a single enclosure housing both types.

Purchasing a 36-volt lithium battery entails a range of considerations. It’s critical to determine the requisite power and the type of bike or vehicle that the battery will be utilized for.
