Custom Lithium Next Generation 280Ah Ultra Slim Lithium Battery

The Custom Lithium Next Generation 280Ah Ultra Slim Lithium Battery is a high-capacity 12V LiFePO4 battery engineered for serious off-grid touring, canopy builds, drawer systems, caravans, and camper installations where maximum usable power is required without sacrificing space. Designed and built for Australian conditions, this battery delivers exceptional energy density in a low-profile, ultra-slim form factor, making it ideal for modern 4WD and touring vehicle builds.

With a massive 280Ah capacity, this battery provides extended runtime for fridges, inverters, induction cooktops, lighting, communications, and high-draw accessories. The advanced internal Battery Management System (BMS) actively monitors and protects against over-charge, over-discharge, short circuit, over-current, and temperature extremes, ensuring long-term reliability and safe operation in demanding environments.

Built using premium LiFePO4 chemistry, the Next Generation 280Ah battery offers high cycle life, stable performance, and consistent voltage delivery, even under heavy loads. Its ultra-slim design allows for flexible mounting in tight spaces such as behind seats, inside drawer systems, under trays, or within canopies — perfect for clean, professional electrical installs.
