1. What is LiFePO4 Battery Run Time Calculation?

The LiFePO4 (Lithium Iron Phosphate) battery run time calculation estimates how long a battery will last under a specific electrical load. This is essential for planning power requirements in various applications.

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Time (hours)} = \frac{\text{Capacity (Ah)}}{\text{Load (A)}} \]

Where:

\( \text{Capacity} \) — Battery capacity in ampere-hours (Ah)
\( \text{Load} \) — Electrical load in amperes (A)

Explanation: This formula calculates the theoretical run time by dividing the battery's total capacity by the current draw of the connected load.

3. Importance of Battery Run Time Calculation

Details: Accurate battery run time estimation is crucial for designing reliable power systems, ensuring uninterrupted operation, and proper sizing of battery banks for various applications.

4. Using the Calculator

Tips: Enter battery capacity in Ah and load current in A. Both values must be positive numbers (capacity > 0, load > 0).

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for real-world applications?
A: This provides a theoretical maximum. Actual run time may be less due to factors like temperature, battery age, discharge rate, and efficiency losses.

Q2: What's the difference between Ah and Wh?
A: Ah (ampere-hours) measures charge capacity, while Wh (watt-hours) measures energy capacity. For accurate power calculations, consider both voltage and current.

Q3: How does depth of discharge affect LiFePO4 batteries?
A: LiFePO4 batteries typically allow 80-100% depth of discharge, but shallower discharges can extend battery life significantly.

Q4: Can this calculator be used for other battery types?
A: The basic formula works for all battery types, but actual performance varies significantly between chemistries (lead-acid, Li-ion, NiMH, etc.).

Q5: How does temperature affect battery run time?
A: Lower temperatures reduce battery capacity and efficiency, while higher temperatures can increase capacity but may reduce overall battery lifespan.
