Start With the Intended Use

Battery capacity should be selected according to how the vehicle will be used.

A short-distance recreational product does not necessarily require the same battery as a rental vehicle or long-distance leisure product.

Understand Voltage and Capacity

Battery energy is commonly expressed in watt-hours.

A simplified calculation is:

Voltage × Amp-hours = Watt-hours

For example:

48V × 20Ah = approximately 960Wh.

This provides a useful basis for comparing batteries with different voltage and capacity combinations.

Consider Vehicle Weight

Larger batteries add weight.

On a fat tire electric cruiser, the effect may be less noticeable than on a lightweight bicycle, but battery size still affects the overall vehicle.

Consider Customer Expectations

A retailer should know whether customers prioritize:

• Lower price
• Lower weight
• Longer range
• Removable battery
• Dual battery
• Charging convenience

The largest available battery is not always the most commercially appropriate option.

Consider the Market

Different markets may have different vehicle classifications and requirements.

Battery capacity should therefore be selected together with motor power, speed and intended application.

For Distributors

A practical product line can include more than one battery configuration.

For example, a standard configuration can target price-sensitive customers while a larger battery version can target customers who value extended riding time.

This allows the same vehicle platform to serve more than one customer group.
