Custom Lithium Next Generation 200Ah Ultra Slim Lithium Battery

Custom Lithium Next Generation 200Ah Ultra Slim Lithium Battery

The Custom Lithium Next Generation 200Ah Ultra Slim Lithium Battery is a high-capacity, space-efficient power solution engineered for modern 4WD touring, canopy builds, drawer systems, and off-grid setups. Designed to deliver exceptional energy density in a compact form, this battery is ideal where space is limited but reliable power is critical.

Using advanced LiFePO₄ (Lithium Iron Phosphate) cell technology, this 200Ah battery provides stable voltage, fast charging capability, and a long service life — making it well-suited for running fridges, inverters, lighting, communications, and other high-draw accessories. Its ultra-slim profile allows installation in locations where traditional batteries simply won’t fit, including behind seats, inside drawer systems, or against canopy walls.

An integrated Battery Management System (BMS) actively protects the battery from over-voltage, under-voltage, short circuit, over-current, and temperature extremes, ensuring safe operation in harsh Australian conditions. Built with touring and off-road use in mind, the robust casing and internal design handle vibration, heat, and continuous cycling with ease.
