72V Lithium Batteries for Electric Motorbikes: A Complete Guide to 2025

1. What is a 72V lithium battery for electric motorbikes?

A 72V lithium battery for electric motorbikes is a lithium battery with a voltage of 72 volts that supplies power to the motor of the electric motorbike to provide the required electrical energy. Electric motorbikes rely on the electrical energy provided by the battery to drive them, and the higher the voltage, the more power the electric motorbike produces, so 72V batteries are able to provide a high power output. They can also store large amounts of energy in small, lightweight packages because of their superior energy density, which is their distinguishing feature.

72V lithium batteries offer many benefits, not just for electric motorbikes, but also for improved performance and speed in power applications such as tricycles, golf carts and robots. Their greater energy storage capacity also means they can travel longer distances on a single charge. These batteries can also often be recharged quickly, minimising downtime and providing convenience.

2. 72V electric motorbike lithium battery working principle

The working principle of 72V electric motorbike lithium battery is mainly based on the movement of lithium ions between the positive and negative electrodes. In the charging process, lithium ions are dislodged from the positive electrode, embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; in the discharging process, lithium ions are dislodged from the negative electrode, return to the positive electrode through the electrolyte, and release the stored energy.

2.1 Discharging process

When a 72V lithium battery electric motorbike is travelling, electrons are transferred to the motor through the electronics, which propels the motor to turn. At the same time, the lithium ions in the battery leave the negative electrode and pass through the electrolyte solution into the positive electrode and combine with the electrons, releasing the stored energy. In the process, the battery converts chemical energy into electrical and kinetic energy to propel the motorbike.

3. 72V electric motorbike lithium battery types

3.1 Lithium ternary battery (NCM or NCA)

Lithium ternary batteries (NCM) have the advantages of very high energy density and fast charging and discharging, and can be widely used in electric vehicles, tricycles and motorbikes, among other applications.

3.2 Lithium iron phosphate batteries (LiFePO4 or LFP)

Lithium iron phosphate batteries have lower energy density, but stable chemical performance and long cycle life, and can be widely used in electric vehicles, power tools, medical equipment and energy storage equipment and other applications.

4. 72V electric motorbike lithium battery advantages, features

• High range: 72V electric motorbike lithium batteries usually have a large capacity, such as 72V 20Ah lithium batteries can store 1.44kWh when fully charged once, capable of travelling 60 to 80km.
• Powerful power performance: 72V electric motorbikes are usually equipped with high-power motors, such as 800W to 1500W motors, which makes the vehicle perform well in all kinds of road conditions, especially in the rugged mountain roads can also be easily dealt with.
• Extended range: 72V batteries have a higher voltage, allowing electric motorbikes to travel longer distances on a single charge. The increased power efficiency and energy density of these batteries help extend range, allowing riders to go further without worrying about running out of power. This makes 72V electric motorbike batteries ideal for daily commuting or long-distance riding.
• Lightweight, Compact Design: Despite the higher voltage, 72V electric motorbike batteries are typically designed to be lightweight and compact. This allows for easier installation and integration into the motorbike frame. The compact design also helps improve the overall handling and manoeuvrability of the motorbike. Manufacturers have made significant progress in reducing the size and weight of these batteries without compromising their performance.
• Adaptable to a wide range of use scenarios: The 72V electric motorbike is not only suitable for daily urban mobility, but also for long-distance travelling and driving needs on complex roads. Its high-powered motor and long-life battery enable it to perform well in scenarios that require high speed and high range.
• Environmental protection and energy saving: Li-ion batteries contain no heavy metal elements, no pollution, no emissions, no harmful gases and noises, which is a kind of clean energy and helps to improve urban air quality and reduce environmental pollution.
• Durability: The use of high-capacity batteries reduces the frequency of charging and discharging, which extends the service life of the battery. For example, a 72V 38Ah battery is more durable than a 20Ah battery because of its long charging and discharging intervals, which reduces battery loss.
• Speed Adjustment Function: 72V electric motorbikes are usually equipped with a multi-step speed adjustment function, which allows users to switch between different travelling speeds according to actual needs, improving the flexibility and efficiency of use.

5. Disadvantages of 72V lithium batteries for electric motorbikes

While there are many advantages of lithium-ion batteries for 72V electric motorbikes, there are some drawbacks that you should be aware of before using them.

Cost: Lithium-ion batteries tend to be more expensive than other types of batteries. It's because the cathode material of lithium batteries is a rare metal, so it has a higher raw material price. However, with the advancement of technology and the expansion of manufacturing scale, the cost has dropped significantly. But lithium-ion batteries are still more expensive than lead-acid batteries.

Safety: Due to the characteristics of the chemical structure, some lithium batteries have thermal runaway, such as lithium ternary batteries, which are prone to thermal runaway at high temperatures, with a certain risk of spontaneous combustion. Therefore, the battery management system (BMS) of Li-ion ternary batteries is particularly important in the application of electric motorbikes to ensure the safety of use by monitoring the temperature and voltage of the battery.

Charging Requirements: Lithium-ion batteries require specialised charging equipment to charge correctly and safely. They cannot be charged with standard chargers. Lithium-ion battery chargers are more complex and expensive. Improper charging can damage the battery and even cause a fire.

6. Why replace lead-acid batteries in electric motorbikes?

Lead-acid batteries are widely used because of their long development time and low cost, but with the continuous development and progress of lithium battery technology, the cost of lithium batteries and lead-acid batteries is getting smaller and smaller, and is also gradually replacing lead-acid batteries. What are the differences between them?

• Heavy weight: Lead-acid batteries are relatively heavy, increasing the overall weight of an electric motorbike, which not only affects the vehicle's manoeuvrability and flexibility, but also reduces the range. For example, a 72V 20Ah lead-acid battery weighs around 38kg, whereas a lithium-ion battery of the same capacity weighs only 1/3 as much as a lead-acid battery.
• Short service life: Lead-acid batteries have a relatively short service life, with about 350 cycles of charging and discharging, and usually only last about 2-3 years.
• Low energy density: lead-acid batteries have low energy density, which means that under the same size, lead-acid batteries store less power, which will directly affect the range of electric motorbikes.
• Poor low-temperature performance: lead-acid batteries for electric motorbikes are very sensitive to temperature, the best suitable working temperature is 20 degrees to 35 degrees, when the working temperature is lower than 15 degrees, the battery capacity will be significantly reduced, especially in the winter, the battery capacity may only be 60% of the summer or even lower.

Now is the time to upgrade your outdated and bulky electric motorbike lead-acid batteries to our advanced lithium batteries.
