The duration a 48V 17.5 Ah battery will last depends on the power consumption of the devices it powers. To estimate runtime, you can use the formula:
For a 48V battery, the total energy capacity in watt-hours (Wh) is calculated as:
Thus, if you know the wattage of the device, you can easily calculate how long the battery will last.
What Is the Energy Capacity of a 48V 17.5 Ah Battery?
Understanding Energy Capacity
The energy capacity of a battery is crucial for determining how long it can power devices. A 48V 17.5 Ah battery has an energy capacity of:
This means it can theoretically provide up to 840 watt-hours of energy before needing to be recharged.

| Voltage (V) | Amp-Hour (Ah) | Energy Capacity (Wh) |
|---|---|---|
| 48 | 17.5 | 840 |
How Do You Calculate Runtime Based on Power Consumption?
Calculating Runtime
To determine how long your battery will last, divide its energy capacity by the power consumption of your device. For example, if you are using a device that consumes 100 watts:
Chart: Runtime Based on Power Consumption
| Power Consumption (W) | Estimated Runtime (hours) |
|---|---|
| 50 | 16.8 |
| 100 | 8.4 |
| 200 | 4.2 |
| 300 | 2.8 |
What Factors Affect Battery Runtime?
Factors Influencing Runtime
