1. What is Battery Capacity?

Battery capacity measures the total amount of energy a battery can store, typically expressed in watt-hours (Wh). It's calculated by multiplying the battery's voltage by its amp-hour (Ah) rating.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Voltage \) — Battery voltage in volts (V)
• \( Ah \) — Battery capacity in amp-hours (Ah)

Explanation: This calculation gives you the total energy storage capacity in watt-hours (Wh), which helps compare batteries with different voltage and Ah ratings.

3. Importance of Battery Capacity

Details: Knowing your eBike's battery capacity helps estimate range, compare different batteries, and understand charging requirements. Higher capacity means longer range but typically larger/heavier batteries.

4. Using the Calculator

Tips: Enter the battery voltage (common eBike voltages are 24V, 36V, 48V) and the Ah rating (typically between 5Ah and 20Ah for eBikes). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical eBike battery capacity?
A: Most eBike batteries range between 300Wh to 700Wh, with high-performance models reaching 1000Wh or more.

Q2: How does capacity relate to range?
A: As a rough estimate, 10Wh per km is typical, so a 500Wh battery would give about 50km range under normal conditions.

Q3: Can I compare batteries just by Ah rating?
A: No - you must consider both voltage and Ah. A 36V 10Ah battery (360Wh) has less capacity than a 48V 10Ah battery (480Wh).

Q4: What affects real-world battery capacity?
A: Temperature, age of battery, discharge rate, and charging habits all affect actual available capacity.

Q5: How long will my battery last?
A: Most lithium eBike batteries last 500-1000 full charge cycles before capacity drops to 80% of original.
