A 48V 20Ah lithium-ion battery can run for approximately 4 to 10 hours, depending on the load it supports. For instance, if used in a golf cart that draws 20 amps, the battery would last about 1 hour. Conversely, with a lower draw of 5 amps, it could last up to 4 hours.
Understanding Battery Capacity and Runtime
The runtime of a lithium-ion battery is influenced by its capacity (measured in amp-hours) and the power consumption of the device it powers. The formula to estimate runtime is:Runtime (hours) = Battery Capacity (Ah) / Load (A)For a 48V 20Ah battery, if the load is known, you can easily calculate how long it will last.
| Load (A) | Estimated Runtime (Hours) |
|---|---|
| 5 | 4 |
| 10 | 2 |
| 15 | 1.33 |
| 20 | 1 |
Factors Affecting Runtime
Several factors can affect the actual runtime of a lithium-ion battery:
- Discharge Rate: Higher discharge rates can lead to reduced efficiency.
- Temperature: Extreme temperatures can impact battery performance.
- Battery Age: Older batteries may not hold their charge as well as new ones.
- Device Efficiency: The efficiency of the device using the battery also plays a crucial role.
Latest News
