72V20Ah and 60V20Ah lithium batteries, two common specifications for electric motorcycles, when choosing a battery for electric motorcycles, what should we be aware of?
Although these two types of batteries are the same in capacity (both 20Ah), there are significant differences in voltage and performance, which will directly affect the power, range and performance performance of the electric motorcycle. Let's follow the China lithium battery manufacturer LEAD-WIN to discuss next.

The main difference between 72V 20Ah lithium battery and 60V 20Ah lithium battery lies in the battery voltage. That is, the lithium battery pack is different, the voltage of 72V battery is higher than 60V, which means that under the same current, 72V lithium battery system will provide higher power output. It is therefore able to support higher acceleration and higher top speeds, which is especially important for electric motorcycles that require higher power. On the other hand, 60V lithium batteries are typically lighter and suitable for application scenarios that require a lighter design or are more economical.
The capacity of 72V20Ah lithium battery is 72V * 20Ah = 1440Wh = 1.440Kwh
60V20Ah lithium battery has a capacity of 60V * 20Ah = 1200Wh = 1.2Kwh.
This means that the 72V electric motorcycle lithium battery will store more power than the 60V electric motorcycle battery, the driving time, and the range will be longer.
If the motor power and speed of the electric motorcycle are the same, for example, the motor power is the same as 800W, and the speed is 50km, then the theoretical range of the electric motorcycle with 60v20ah lithium batteries is 75km per hour. the theoretical range of the electric motorcycle with 72v20ah lithium batteries is 90km. the higher the motor power and the higher the battery capacity, the more the range. Theoretically the range of 72v20Ah electric motorcycle is about 15km more than 60v20ah electric motorcycle. Specifically, the theoretical range of a 60v20ah electric motorcycle is 75km per hour, while the theoretical range of a 72v20ah electric motorcycle is 90km per hour. This indicates that the higher the voltage, the longer the EV's range. Click on our electric motorcycle page to compare.
Because of the difference between the two cells, battery packs, capacity and stored power, there is a slight difference in price, the price of 72V lithium batteries is slightly higher than the price of 60V lithium batteries, electric motorcycle manufacturers should consider choosing a battery in conjunction with the performance needs of the entire electric motorcycle, range and overall cost-effectiveness.
72V20Ah and 60V20Ah are commonly used in the field of electric motorcycle, and the difference in appearance and size is generally not too big, therefore, many countries and regions will be combined with electric motorcycle battery swapping station together. In general, 60V20Ah lithium batteries meet the needs of electric motorcycles for personal use in daily life, while for commercial use, such as courier transport, food delivery services, passenger and cargo, 72V 20Ah lithium batteries can meet the needs of electric motorcycles.
Both 72V 20Ah and 60V 20Ah lithium batteries use similar charging protocols and BMS technology. This includes charger design, battery protection circuitry, and charge control systems, making them somewhat similar in terms of charging process and battery life management.
Overall, the difference between 72V20Ah lithium batteries and 60V20Ah lithium batteries is not very big, and the application areas between them are roughly the same, and they can also be used with the battery swapping cabinet, choose the right electric motorbike battery, for individuals, need to consider the price and practicality according to their own specific use; For electric motorcycle manufacturers, it is more important to consider the performance requirements and cycle life of the whole vehicle.
