72V20AH Electric Car Charger for Lead-Acid Batteries with 2.5A Output

This power unit serves as a dedicated charging solution for electric vehicles utilising 72V20AH lead-acid battery packs. Designed for functionality, it converts standard mains electricity into a stable DC72V output with a current of 2.5A. The charger addresses the need for a reliable power source that maintains battery health while fitting within the operational parameters of professional and personal electric mobility devices. Its straightforward design prioritises consistent performance over unnecessary features.

Technical Specifications

The core identity of this charger lies in its specific voltage and current ratings which match distinct battery requirements.

Power Input and Output

The device accepts an input voltage ranging from 180V to 226V, making it suitable for various grid conditions within this band. It transforms this input into a direct current output of 72V, specifically targeting the 20AH capacity range. The charging current is fixed at 2.5A, a rate chosen to balance charging speed with the safety limits of lead-acid chemistry. This ensures the battery receives power without exceeding thermal or chemical thresholds defined by its construction.

Physical Dimensions

Measuring 165mm in length, 87mm in width, and 63mm in height, the charger occupies minimal space. These dimensions allow it to be stored in saddlebags or mounted in tight compartments on electric vehicles. The compact size does not compromise the internal spacing required for heat dissipation during the charging cycle. Users can easily position the unit on a floor or shelf without obstructing walkways.

Compatibility and Usage

Proper application of this charger depends on matching the vehicle's battery specifications to the unit's output profile.

Battery Suitability

This charger is exclusively compatible with lead-acid batteries rated at 72V20AH. It is not designed for lithium-ion or other chemistries unless explicitly stated by the vehicle manufacturer. The scope of application covers professional electric vehicles and consumer e-mobility products that adhere to this standard voltage and capacity. Using it on mismatched batteries may result in inefficient charging or potential damage.

Regional Configuration

To accommodate different geographic locations, the charger is available with AU, EU, or US plug styles. This flexibility allows the same internal charging technology to be deployed across multiple markets. Users must select the correct option at the point of purchase to ensure the physical plug fits their local wall sockets. The electrical performance remains consistent regardless of the chosen plug configuration.

Practical Benefits

Owning a dedicated charger ensures that the electric vehicle remains operational and ready for use.

Operational Reliability

By providing a stable 2.5A current, the charger helps maintain the longevity of lead-acid cells. Consistent voltage regulation prevents the fluctuations that can degrade battery performance over time. This reliability is crucial for users who depend on their electric vehicles for daily transport or professional duties. The unit functions as a stable bridge between the power grid and the vehicle's energy storage.

Design Efficiency

The black finish and utilitarian shape reflect a focus on function. The 165mm by 87mm footprint is optimised for practical handling and storage. There are no superfluous elements; the design exists solely to deliver the specified 72V20AH charging capability. This straightforward approach ensures that the user pays for essential performance rather than cosmetic additions.
