How long will a 48V battery last?

When a 48V 20Ah lithium battery is paired with a 350W or 400W motor, the theoretical range is approximately 60-68 kilometres. In actual use, due to factors such as load, road conditions, and driving habits, the typical range is 55-60 kilometres. Taking the 350W motor as an example, the average current during constant-speed operation is 7.3A, with a theoretical runtime of about 2.7 hours, while the 400W motor provides a range of 60 kilometres. Note that low-temperature conditions can reduce range by 20%-30%, and each additional 10kg load may decrease range by 5%-8%. For daily commuting, a 48V 20Ah battery can accommodate one-way trips of 10 kilometres, requiring charging approximately every 2-3 days, which represents a standard configuration for urban users.
