1. What is Battery Bank Capacity?

Battery bank capacity refers to the total energy storage capacity when batteries are connected in parallel. It's measured in ampere-hours (Ah) and determines how long your system can power devices.

2. How Does the Calculator Work?

The calculator uses the parallel battery bank formula:

Where:

• \( Battery\ Ah \) — Individual battery capacities in ampere-hours
• \( \sum \) — Sum of all battery capacities

Explanation: When batteries are connected in parallel, their capacities add up while voltage remains the same.

3. Importance of Battery Bank Calculation

Details: Accurate battery bank calculation is crucial for designing power systems, determining runtime, and ensuring proper system sizing.

4. Using the Calculator

Tips: Enter battery capacities in Ah separated by commas (e.g., "100, 100, 200"). All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I mix different capacity batteries in parallel?
A: While possible, it's not recommended as it can lead to uneven charging and reduced battery life.

Q2: Does this apply to series connections?
A: No, series connections increase voltage while capacity remains the same as a single battery.

Q3: What's the difference between Ah and Wh?
A: Ah measures charge capacity, while Wh (watt-hours) measures energy capacity (Ah × Voltage).

Q4: How does temperature affect battery capacity?
A: Cold temperatures reduce available capacity, while high temperatures can increase capacity but reduce lifespan.

Q5: Should I include all batteries in the calculation?
A: Only include batteries that are actively connected in parallel in your system.
