Battery Sizing Calculator
Calculate the battery capacity needed for your application
100W
5 hours
Required Capacity:0 Ah
Recommended Battery:
Daily Energy Consumption: 500 Wh/day
How to Use This Calculator
To get the most accurate recommendation, follow these steps:
- Select Battery Type: Choose between Lithium-Ion and LiFePO4 based on your application needs.
- Enter Load Power: Input the total power consumption of your devices in watts.
- Specify Usage Time: Enter how many hours per day you'll be using the battery.
- Set System Voltage: Select the voltage of your system (typically 12V, 24V, or 48V).
- Advanced Settings: For more precise calculations, adjust days of autonomy and depth of discharge in the Advanced tab.
Understanding the Results
The calculator provides two key outputs:
- Required Capacity: The minimum battery capacity in Amp-hours (Ah) needed for your application.
- Recommended Battery: The specific ampereX battery model that best meets your requirements.
Calculation Methodology
Our calculator uses the following formula to determine the required battery capacity:
Required Capacity (Ah) = (Load (W) × Hours per Day × Days of Autonomy) ÷ System Voltage (V) ÷ (Depth of Discharge ÷ 100)
This formula accounts for your power needs, usage duration, and battery efficiency to ensure you get a solution that provides reliable power for your application.
