CASE STUDY: Powering Business on the Move

How a professionally engineered Fogstar battery system gives mobile businesses the freedom to operate wherever opportunity takes them.

For many businesses, success isn't defined by a fixed location. Whether it's a mobile coffee trailer, catering unit, exhibition vehicle or specialist commercial build, taking your business on the road creates exciting opportunities to meet customers wherever they are. But with that freedom comes a challenge, delivering reliable power throughout the working day without relying on a mains hook-up.

That's exactly the challenge JC Auto Electrical set out to solve with this bespoke catering trailer installation. Designed around the Fogstar Drift 48V battery, the completed system demonstrates how modern lithium technology can deliver dependable off-grid power for demanding commercial applications, allowing businesses to focus on serving customers rather than managing their electrical system.

Designed Around Real-World Demands

Every installation begins with understanding how the customer intends to use their vehicle.

For this project, JC Auto Electrical needed to design a system capable of delivering high levels of continuous power from a relatively compact installation space. Commercial catering equipment places significant demands on an electrical system, requiring careful consideration of battery capacity, inverter sizing and charging performance to ensure reliable operation throughout the day.

Using in-house load calculations, JC Auto Electrical designed a bespoke Victron Energy system built around two Fogstar Drift 48V 125Ah lithium batteries, providing enough stored energy to comfortably support the trailer's daily operation before recharging overnight. Supported by 430W of roof-mounted solar, the system helps maximise efficiency while extending runtime whenever conditions allow.

"We use Fogstar batteries for around 90% of our installations. The build quality, ease of installation and reliability are exactly what we're looking for."

Built to Keep Business Moving

Reliable power is essential when your business depends on electrical equipment.

This installation was designed to comfortably support the high-demand appliances required throughout a full trading day, while also providing the flexibility to operate completely off-grid.

The finished system incorporates premium Victron Energy components, including a 48V Victron MultiPlus inverter, MPPT solar controller, DC converter and Cerbo GX monitoring system, giving the operator complete visibility of the electrical system while ensuring every component works seamlessly together.

Rather than worrying about where the next hook-up is, the owner can simply concentrate on serving customers, confident that the electrical system has been designed to perform.

Why JC Auto Electrical Chooses Fogstar

Having installed Fogstar batteries across a wide range of campervan, leisure and commercial vehicle projects, JC Auto Electrical continues to specify the Drift range for the same reasons; reliability, straightforward installation and dependable performance.

The introduction of Fogstar's battery mounting trays has further streamlined installations, reducing fabrication time while delivering a secure, professional finish.

More importantly, the batteries have consistently delivered where it matters most: in real-world use.

After fitting countless Fogstar batteries across a variety of applications, JC Auto Electrical has experienced outstanding reliability, backed by responsive UK-based technical support whenever it's needed.

Proven in Real-World Use

Before being handed over, the completed installation underwent a full day of real-world testing under heavy electrical loads.

The results spoke for themselves. The system performed exactly as intended, comfortably supporting continuous inverter demand throughout the day while providing the confidence that the trailer could operate independently without compromise.

It's exactly the kind of performance professional installers expect from a premium lithium battery system, and exactly why JC Auto Electrical continues to specify Fogstar across the vast majority of its installations.

The Result

The best mobile businesses aren't defined by where they're based, they're defined by where they can go.

Whether it's serving customers at markets, festivals, sporting events or private functions, reliable off-grid power allows businesses to operate wherever opportunity takes them.

This installation demonstrates how a professionally engineered electrical system, built around the Fogstar Drift 48V battery, delivers the performance, reliability and confidence needed to keep business moving.
