A 100Ah LiFePO4 battery typically provides an energy capacity of 1280 watt-hours (Wh) when operating at its nominal voltage of 12.8 volts. This means it can deliver 1280 watts for one hour or proportionally less for longer durations, making it ideal for various applications.
What is the energy capacity of a 100Ah LiFePO4 battery?
The energy capacity of a 100Ah LiFePO4 battery can be calculated using the formula:
For a standard 12V configuration, this results in:
However, many LiFePO4 batteries have a nominal voltage around 12.8V, leading to an energy capacity of approximately 1280Wh.
Energy Capacity Calculation
| Configuration | Voltage | Capacity | Total Energy |
|---|---|---|---|
| 12V | 12V | 100Ah | 1200Wh |
| Nominal | 12.8V | 100Ah | 1280Wh |
How do you calculate the watt-hours of a 100Ah LiFePO4 battery?
To calculate the watt-hours (Wh) of a 100Ah LiFePO4 battery, you multiply the nominal voltage by the amp-hour rating:
For example, using a nominal voltage of 12.8V:
This calculation indicates how much energy the battery can store and deliver over time.
Watt-Hours Calculation Example
| Nominal Voltage | Capacity | Watt-Hours |
|---|---|---|
| 12.8V | 100Ah | 1280Wh |
What is the nominal voltage of a 100Ah LiFePO4 battery?
The nominal voltage for most 100Ah LiFePO4 batteries is typically around 12.8 volts, which is derived from individual cells rated at 3.2 volts each. This configuration usually consists of four cells connected in series.
Nominal Voltage Breakdown
| Cell Configuration | Voltage per Cell | Total Voltage |
|---|---|---|
| Single Cell | 3.2V | 3.2V |
| Four Cells (12V) | 3.2V | 12.8V |
Why is understanding wattage important for battery applications?
Understanding wattage is crucial because it helps users determine how long their devices can run on the stored energy within the battery. For instance, knowing that a 100Ah LiFePO4 battery provides 1280Wh, users can estimate runtime for various appliances by dividing total watt-hours by the appliance’s power consumption.
Runtime Calculation Example
| Appliance | Power Consumption (Watts) | Runtime (Hours) |
|---|---|---|
| LED Light | 10W | 1280�ℎ/10�=128 hours |
| Small Fridge | 150W | 1280�ℎ/150�=8.53 hours |
| Laptop | 50W | 1280�ℎ/50�=25.6 hours |
How long can a 100Ah LiFePO4 battery run various devices?
The runtime provided by a 100Ah LiFePO4 battery varies based on the power consumption of connected devices. For example, if you connect devices that collectively consume 200 watts, you can expect approximately:
This calculation helps in planning energy needs for activities such as camping or emergency backup.
Runtime Estimation Table
| Device | Power Consumption (Watts) | Estimated Runtime (Hours) |
|---|---|---|
| LED Light | 10W | 1280/10=128 |
| Laptop | 50W | 1280/50=25.6 |
| TV | 100W | 1280/100=12.8 |
| Refrigerator | 150W | 1280/150= 8.53 |
