Product Info
Bundle Contents
The iTechworld Power Core is a powerful all-in-one 12V system, ideal for 4WD canopies, touring vehicles or off-grid living. It delivers reliable, high-performance power without the time, cost, or complexity of traditional installations.
Four separate components come pre-wired in one industrial-grade case: a 2000W PRO pure sine inverter with ATS and RCD, a 40A DC-DC charger, a 40A AC charger, and a 500A battery monitor. Instead of mounting, wiring and fusing each one individually, the work is already done. Heavy gauge copper wiring, resettable circuit breakers and pre-fitted ANL fuses throughout.
What's inside
iTECH2000WPRO inverter — 2000W continuous, 4000W peak, 240V pure sine wave output. Safe for laptops, TVs, CPAP machines and other sensitive electronics. Built-in ATS switches to mains power within 30ms when you pull into a powered site, so you can run from 240V without unplugging anything.
iTECHDCDC40 charger — 40A of charging from your alternator while you drive, or from an unregulated solar panel up to 32V. Selectable profiles for LiFePO4, AGM, GEL, Calcium and standard lead acid.
iTECHBC40 charger — 40A of 240V mains charging. Run both chargers together for up to 80A into the battery.
iTECHBM500 battery monitor — 500A shunt with a display showing state of charge, Ah remaining, time remaining, voltage, amperage and wattage. You know exactly what's left, not a rough guess from voltage.
Four ways to charge
Alternator while driving, unregulated solar direct to the DC-DC input, regulated solar via the Anderson inputs, or 240V mains using the included AC input cable. Most people use two or three depending on where they are.
Power and accessory outputs
Four backlit 20A rocker switches for lights, pumps and switched circuits. Two 50A IN/OUT Anderson plugs, a 12V 15A cigarette socket, an 18W QC3.0 USB port and a 30W USB-C port. Unswitched loads like a fridge wire directly to the circuit breaker interface.
Left or right orientation
Choose the variant that suits your build. The orientation determines which side the charger inputs and terminals sit on, so pick the one that puts your cable entry closest to your battery and vehicle wiring.
Installation
The Power Core mounts upright on a flat, stable surface such as a canopy wall, vehicle frame or timber backing panel. Allow at least 100mm clearance on the DC-DC input side and around the fuse access panel. Connect the battery before final mounting, as the terminals are accessed from underneath.
iTechworld recommends installation by a certified technician, and a licensed electrician for the 240V AC input connection.

Power Core User Guide
Power Core User Guide
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.
