iTechworld Ultra Slim iTECH300US Deep Cycle Lithium Battery with Bluetooth LiFePO4 300Ah

The iTECH300US Ultra Slim is designed for installations where every millimetre counts. It fits neatly behind seats, under false floors, inside canopies, or any other tight space. Designed in Australia and refined through years of research and testing, it represents the culmination of iTechworld’s commitment to innovation. Don’t let its slender profile fool you! This 12V LiFePO4 battery delivers a massive 300Ah capacity, enough to power fridges, lighting, and other high-demand devices for extended off-grid trips, all within the smallest footprint on the market.

Reinforced Internal Structure

Whether navigating corrugated outback tracks or tackling rugged overland routes, the internal support framework has been specifically engineered to absorb shocks, impacts and vibrations that could otherwise affect the cells. Developed through extensive in-house research, this brace ensures your battery performs reliably wherever you take it.

Ultra Slimline Profile

Measuring just 82mm thick, the iTECH300US is Australia’s slimmest lithium battery, made to fit in almost any installation. It slips effortlessly under false floors, inside canopies, behind seats, and into other confined spaces, delivering full-sized power where conventional batteries just won’t fit.

Industry Leading Design

The iTECH300US’ slimline construction reduces overall size while maintaining impressive energy density, made possible by premium A-grade prismatic cells. This advanced engineering allows it to outperform larger batteries that rely on less sophisticated technology, giving reliable power in a compact form.

High Discharge BMS

The iTECH300US features a Battery Management System (BMS) capable of 200A continuous discharge and 640A peak, letting you confidently run high-demand devices such as fridges, power tools, or a 3000W inverter. Whether you’re off-grid, traveling, or running a mobile workstation, it delivers smooth and dependable energy when and where you need it.

Bluetooth Connectivity

Built-in Bluetooth allows you to monitor your battery’s key stats via the iTechworld Connect Battery Management App. You can also manage your system from up to 10 metres away, making it easy to track performance and adjust settings without being near the battery.

Weight Saving

A comparable AGM battery weighs over 160kg, while the iTECH300US is just 31.2kg, more than 128.8kg lighter. This significant weight reduction makes transporting, installing, and moving the battery far easier, a crucial advantage for off-grid trips or tight installations.
