PRE-WIRED & ULTRA COMPACT

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, making it ideal for anyone looking for a plug-and-play power system.

ALL-IN-ONE PLUG AND PLAY SOLUTION

The Power Core combines a 2000W PRO inverter, a 40A DCDC charger, a 40A ACDC charger, a battery monitor with a shunt, fused switches, 50A Anderson & USB outputs into a single, pre-wired unit. Allowing for easy installation, simply connect the positive and negative terminals, and your system is ready to go! This makes it perfect for DIY installations, saving both time and money.

2000W PRO INVERTER WITH ATS & RCD

The integrated inverter delivers 2000 Watts of pure sine wave power, safely and efficiently handling high-draw appliances. The twin AC outputs are RCD protected (Twin TYPE-I plugs), offering peace of mind when running sensitive devices, while an automatic transfer switch ensures seamless power delivery without interruption if connected to the grid.

DUAL 40A CHARGING

With built-in iTECHBC40 and iTECHDCDC40 chargers, the Power Core can recharge from AC 240v mains, alternators and solar power. This means your batteries can be replenished faster, keeping your system ready for extended trips. Dual charging also offers versatility for charging from different power sources. 

ADVANCED BATTERY MONITORING

The built-in iTECHBM500 provides real-time state of charge (SOC) and power usage information at a glance. You can see exactly how much power you have left and monitor system performance under load, ensuring you always know your battery's status and can plan your activities in advance. 

FLEXIBLE LEFT/RIGHT ORIENTATION

The Power Core can be installed with either left or right facing orientation, giving you the freedom to match your canopy or vehicle layout perfectly. This flexibility ensures a neat, space-conscious installation regardless of your setup's configuration. It makes it simple to integrate into tight spaces while keeping all connections accessible and organised for easy maintenance. 

FULLY PRE-FUSED BUILD

Every circuit is pre-wired with either an RCD, breaker or fuse for maximum safety, while eight resettable circuit breakers allow quick resets without replacing fuses. The industrial-grade coated steel, thick copper cabling and backlit rocker switches are designed to withstand harsh Aussie conditions. The exposed fuse layout and supplied mounting hardware make installation, inspection and maintenance straightforward.

CERTIFIED

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.
