The future of mobile grooming has officially arrived.

Introducing the all-new Mercedes-Benz eSprinter, now fully converted and available through Hanvey Engineering & Design.

This isn't simply a van conversion. It's a glimpse into the future.

Clean. Efficient. Innovative. Purpose-built by Hanvey Engineering & Design.

Lithionics Power System – Off-Grid Innovation

At the heart of today’s most advanced mobile grooming vans is the Lithionics lithium battery system, built for reliability, sustainability, and total independence on the road.

Paired with high-efficiency solar panels, the system delivers continuous renewable power wherever you go. The short-body van features up to 800 watts of solar, while the long-body model offers up to 1,000 watts, allowing your salon to run all day using clean energy from the sun.

With the VRM (Virtual Remote Monitoring) system, you can monitor your van’s battery levels, solar production, energy consumption, and system performance 24 hours a day, 7 days a week, right from your phone or device—no matter where you are in the country.

The result is a mobile salon that operates quietly, efficiently, and often completely off-grid, reducing your carbon footprint while giving you the freedom to groom anywhere.

Because anyone can add lights and equipment to a van.
But true innovation comes from engineering a system that powers your entire business.

Lithionics Never Die.🚐💯⚡️⚡️
