1. What is the LiPo Battery Run Time Calculator?

The LiPo (Lithium Polymer) Battery Run Time Calculator estimates how long a battery will last under a specific load. It's essential for designing battery-powered systems and understanding power requirements.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{LiPo Capacity} \) — Battery capacity in amp-hours (Ah)
• \( \text{Voltage} \) — Battery nominal voltage (V)
• \( \text{Load} \) — Power consumption of the device (W)

Explanation: The equation calculates the total energy stored in the battery (capacity × voltage) and divides it by the power consumption to determine how many hours the battery can sustain the load.

3. Importance of Run Time Calculation

Details: Accurate run time estimation is crucial for designing reliable battery-powered systems, selecting appropriate battery sizes, and planning for recharging intervals.

4. Using the Calculator

Tips: Enter battery capacity in Ah, nominal voltage in V, and load in W. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mAh and Ah?
A: 1 Ah = 1000 mAh. The calculator uses Ah for consistency with the power formula.

Q2: Does this account for battery efficiency?
A: No, this is a theoretical maximum. Real-world results may be 10-20% lower due to efficiency losses.

Q3: What voltage should I use for multi-cell batteries?
A: Use the nominal voltage (3.7V per cell). For example, a 3S battery would be 11.1V (3 × 3.7V).

Q4: How does discharge rate affect run time?
A: High discharge rates can reduce effective capacity. Check your battery's C-rating for maximum safe discharge.

Q5: Can I use this for other battery types?
A: The formula works for any battery type, but the results are most accurate for LiPo batteries.
