Why Choose Li-Gen

Li-Gen batteries are not just a replacement — they’re a transformation.

Our technology is redefining what’s possible in mobile, off-grid, and stationary energy applications.

Key Advantages

• Up to 50% More Power
• Lithium delivers virtually all available energy at a consistent voltage, without the slow fade-out typical of lead batteries.
• Ultra-Long Life – Thousands of Cycles
• Designed for durability, our batteries maintain performance even under partial charge conditions, with a service life exceeding several thousand cycles.
• High Efficiency (up to 99%)
• Less wasted energy means faster returns on investment. Our batteries achieve over 90% efficiency even under shallow charge/discharge cycles.
• Rapid Charging
• Lower internal resistance allows for much faster charge times — particularly in the final 30% phase where lead batteries slow dramatically.
• Lightweight & Compact
• Around 40–50% lighter than equivalent lead batteries, improving mobility, payload, and installation flexibility.
• Orientation in Any Direction
• Using premium 32700 cylindrical and prismatic cells, Li-Gen batteries can be installed in any position — ideal for compact or irregular spaces.
• Safety Built In
• Smart Battery Management Systems (BMS) prevent overcharge, deep discharge, and low-temperature damage, ensuring safe and stable performance.
• Environmentally Responsible
• Free from toxic heavy metals, Li-Gen lithium batteries dramatically reduce waste, recycling frequency, and carbon footprint — contributing to a cleaner, more sustainable planet.
• Drop-In Compatibility
• Li-Gen batteries are designed as direct replacements for lead-acid, AGM, and gel variants. No additional components or system reconfiguration are required.

Sector Expertise

Golf and Leisure Industry

Did you know there are more than 9,000 golf courses in Europe and the shift toward electric and hybrid golf buggies has created unprecedented demand for lightweight, durable batteries.

Li-Gen supplies golf clubs, buggy manufacturers, and fleet managers with lithium battery packs that deliver:

• Longer range between charges.
• Consistent power delivery throughout play.
• Faster charging turnaround.
• Minimal maintenance and total reliability.

These features not only enhance player experience but also reduce operating costs and downtime for golf course operators.

Motorhome and Caravan Market

The UK motorhome and caravan industry is valued at £9.3 billion annually, with over 225,000 registered motorhomes and one of the fastest-growing leisure sectors in Europe.

Li-Gen batteries provide clean, lightweight, and long-lasting power for off-grid living. With direct drop-in replacement capability and higher usable capacity, our batteries extend the freedom and comfort of mobile leisure travel.

Marine Leisure Craft

In the marine market, reliability and safety are paramount. Li-Gen lithium batteries are resistant to vibration, compact in size, and safe to mount in any orientation — ideal for sailboats, cruisers, and commercial vessels alike.

The result: quieter operation, reduced weight, and dependable onboard power for navigation, communications, and comfort systems.

Material Handling and Industrial Vehicles

From forklifts to cleaning machines, Li-Gen’s industrial-grade lithium solutions deliver constant power output and dramatically reduce downtime. Their long lifespan and fast-charge capability make them the intelligent choice for logistics and manufacturing environments where uptime is critical.

Environmental Commitment

At Li-Gen, sustainability isn’t a slogan — it’s the foundation of everything we do.

Our lithium-iron phosphate (LiFePO₄) chemistry offers a safe, non-toxic alternative to lead and other harmful materials. By significantly extending product life cycles and reducing the need for frequent replacement, we help clients minimise both operational costs and environmental impact.

We actively collaborate with businesses across Europe to support their carbon reduction goals through energy efficiency, circular design, and responsible manufacturing practices.
