Lithium Leisure Batteries

Upgrade your camper van electrical system with high-performance lithium leisure batteries from Wired Campers, designed to deliver reliable, lightweight and long-lasting off-grid power. Ideal for campervan conversions, motorhomes, caravans and marine applications, these advanced LiFePO4 batteries provide a superior alternative to traditional AGM and lead-acid batteries.

Lithium leisure batteries are engineered to store and deliver consistent 12V power for essential onboard appliances including fridges, lighting, water pumps and inverters. Compared to conventional batteries, lithium technology offers significantly longer cycle life, faster charging and higher usable capacity, making it the go-to choice for modern campervan electrics. Many lithium batteries can achieve thousands of charge cycles and maintain stable voltage output throughout discharge, ensuring reliable performance for off-grid living. 

This collection features industry-leading brands such as Roamer and Fogstar, offering a wide range of capacities from compact 100Ah batteries to high-capacity 460Ah and 560Ah systems for full off-grid setups. Whether you need a space-saving seat base battery or a high-capacity solution for extended travel, there are options to suit every build. Heated lithium battery models are also available, allowing safe operation and charging in colder climates—perfect for year-round van life. 

Designed with safety and convenience in mind, many lithium leisure batteries include integrated Battery Management Systems (BMS) to protect against overcharge, over-discharge, overheating and short circuits. This ensures optimal performance and longevity while reducing maintenance compared to traditional battery types. Lightweight construction also makes installation easier, with lithium batteries typically weighing significantly less than equivalent lead-acid options. 

For advanced users, smart lithium batteries with Bluetooth monitoring allow real-time tracking of voltage, current and battery status via mobile apps, giving you complete control over your campervan power system. Combined with compatible DC-DC chargers, solar MPPT controllers and 12V distribution systems, these batteries form the core of a fully integrated off-grid electrical setup.
