How many kilometers can a 72V lithium battery run?

The theoretical driving range is approximately 108 kilometers. However, in actual road conditions, it is around 80 kilometers. More details about the 72V lithium battery are as follows: Average current at constant speed: Average current at constant speed = Power / Voltage = 1500W / 72V = 20.8A. Speed of 45 km/h: Calculating the theoretical driving range at a speed of 45 km/h = Driving time × Speed = 2.4H × 45KM/H = 108 kilometers. After a full discharge, charging once requires about 4.06 kWh of electricity. The charging capacity is generally 1.05 times the battery discharge capacity. Based on the charging voltage, the electricity consumption = Charging voltage × Battery rated capacity × 1.05.

The actual range of a 72V lithium battery depends on various factors, as voltage is just one aspect. The battery capacity plays a crucial role. For instance, a common 72V 20Ah battery used in an electric vehicle can typically cover about 60 to 80 kilometers under moderate speed and flat road conditions. However, with a larger capacity like 72V 50Ah, the range can exceed 100 kilometers. The battery's condition also affects performance—new batteries may offer longer ranges, while aged ones degrade. Riding habits matter too; faster speeds or frequent uphill rides increase power consumption, potentially halving the range. It's advisable to maintain a steady speed and avoid windy conditions. Seasonal changes impact performance as well—cold winters reduce lithium battery discharge efficiency, and extreme summer heat may shorten lifespan. Overall, before purchasing a battery, check the vehicle specifications and capacity, not just the voltage. For daily use, regular maintenance can extend battery life and prevent the inconvenience of running out of power mid-journey, which is particularly practical for commuting.

As a long-term e-bike rider, my experience with 72V batteries is: with a standard capacity of 20Ah, a full charge can last about 70 kilometers, but this is just an average. I remember last summer when I rode to the suburbs for fun, with smooth roads and less traffic, maintaining steady throttle, I completed a round trip of 60 kilometers and still had battery left; in winter, when I rushed and rode faster, the same distance might only last 40 kilometers before the battery alarm went off. There are many factors affecting the range, such as slower discharge when the battery temperature is low, and overheating when the temperature is high. The weight of the vehicle is also crucial; carrying passengers or cargo will definitely shorten the range. Personally, I suggest paying attention to the ampere-hour (Ah) rating when purchasing, and not blindly trusting the 72V label; develop good habits when using the bike, such as avoiding sudden acceleration and windy days; replace the battery promptly when it ages. If you can choose a lithium battery brand with temperature protection, the range will be more stable. In short, adjust flexibly according to different riding scenarios, and don't expect a fixed number.

The range of a 72V lithium battery primarily depends on its capacity. Simply put, 10Ah roughly corresponds to 50 to 70 kilometers. If installed on a standard electric bike or electric scooter, a 72V 20Ah battery can support around 60 kilometers, while a 72V 30Ah battery might reach 90 kilometers. However, variables must be considered: if the speed is too high, such as above 60 km/h, wind resistance can cut the range by half; rough road conditions or frequent stops and starts also drain the battery faster. Additionally, battery type matters—lithium batteries are more efficient than lead-acid but are affected by temperature, performing better in summer and dropping by about 20% in winter. It's advisable to check battery health before each charge and use a dedicated charger to avoid overcharging. For long trips, estimate the range in advance and avoid pushing the battery to low levels. These practices will help you ride with greater peace of mind.
