How Long Does A 48v Battery Last? Lifespan of 48v Battery
A 48V Battery is used in the majority of electric bikes as this battery provides a longer lifespan and excellent efficiency. But do you know how long does a 48v battery last?
Although it depends on several factors like the amp hour of the battery, power of the e-bike, type of surface, speed, etc., a 48v battery normally lasts around 3 hours on average.
In this article, we will explain how long a 48v battery lasts, what factor the longevity of this battery might very, and much more regarding this. Let’s explore them below!
Factors That Affect the Longevity of 48V Battery?
As we mentioned already, how long a 48v battery will last depends on several factors. Among all, here are the two main factors that affect the longevity of the battery:
- Amp-hours of the battery: The range for a 48v battery depends on its Amp-hours (ah). If the battery has a higher AH, it will last longer.
- The Power of the motor: How long the 48v battery will last, also depends on how many watts the motor is going to use the battery. If the motor has lower power, the battery will last longer.
Also, there are other factors that impact the longevity of a 48v battery such as –
- The type of terrain,
- The weight of the rider,
- The weather conditions,
- The speed of the motor, and
- For how long the motor will run.
Does a 48v Battery Expire?
From the above discussion, now you know what affects the longevity of a 48V battery for one charge. Now, let’s calculate the longevity of the battery.
How long will a battery last, depends on its watt-hour. For example, 100 wh means the battery will last 1 hour for 1 watt motor.
Here, watt-hour (wh) = volt (v) x amp-hour (ah)
So, if a 48v battery has 20ah, the watt-hour will be 48v x 20ah = 960wh.
It means it will last 1 hour for a 960w motor.
Now, if an e-bike has a 250w motor, the 48v 20ah battery will last for 3-4 hours.
Similarly, a 48v battery has 10ah, the watt-hour will be 48v x 10ah = 480wh. This means it will last 1 hour for a 480w motor and will last around 2-3 hours for a 250w motor.
How Long Will A 48V 10AH Battery Last?
Generally, a 48v 10ah battery has an electric power of up to 480wh. For this, it can be paired with 250w, 350w, and 500w motors. Here is how long a 48v 10ah battery would last:
| Motor Power | Estimated Time |
| 250-Watt | 2 hours |
| 350-Watt | 1.5 hours |
| 500-Watt | 1 hour |
How Long Will A 48v 20ah Battery Last?
Generally, a 48v 20ah battery has an electric power of up to 960wh. For this, it can be paired with 500w, 750w, and 1000w motors. Here is how long a 48v 20ah battery would last:
| Electric Bike Motor | Estimated Time |
| 500-Watt | 2 hours |
| 750-Watt | 1.5 hours |
| 1000-Watt | 1 hour |

How Many Kilometers Will a 48v Battey Last?
When it comes to distance, a 48v battery lasts around 50 to 65 kilometers per charge. However, it may vary depending on various factors.
How Far Can A 48V 13AH Battery Go?
A 48v 13ah battery has 625wh power. So, if it is paired with a 250w motor, it can last up to 2.5 to 3 hours. If the e-bike is driven at around 22km/h speed, it can last up to 65 kilometers.
Conclusion
The basic factors and equation to calculate how long a 48v battery will last are provided and explained in this article. Hopefully, now you can easily calculate the longevity of your 48v battery. However, the longevity of the battery may change depending on other factors like type of road, speed, weight, and environment.
