1. What is LiFePO4 Runtime Calculation?

LiFePO4 (Lithium Iron Phosphate) runtime calculation estimates how long a battery will last under a specific load. It's essential for designing power systems and ensuring adequate backup time.

2. How Does the Calculator Work?

The calculator uses the simple runtime formula:

Where:

• \( \text{Capacity} \) — Battery capacity in Ampere-hours (Ah)
• \( \text{Load} \) — Current draw in Amperes (A)

Explanation: This formula calculates the theoretical runtime by dividing the battery's total capacity by the current consumption rate.

3. Importance of Runtime Calculation

Details: Accurate runtime estimation is crucial for battery sizing, system design, and ensuring uninterrupted power supply for critical applications.

4. Using the Calculator

Tips: Enter battery capacity in Ah and load current in A. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for real-world scenarios?
A: This provides theoretical runtime. Actual runtime may vary due to temperature, battery age, discharge rate, and other factors.

Q2: What's the typical capacity range for LiFePO4 batteries?
A: LiFePO4 batteries typically range from 10Ah to 300+Ah, with various configurations available for different applications.

Q3: How does discharge rate affect runtime?
A: Higher discharge rates can reduce actual capacity due to internal resistance and heating effects, slightly reducing runtime.

Q4: Should I consider depth of discharge?
A: Yes, for optimal battery life, it's recommended to limit discharge to 80-90% of total capacity for LiFePO4 batteries.

Q5: Can this calculator be used for other battery types?
A: While the formula is universal, different battery chemistries have varying characteristics that affect actual performance.
