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

A$ 2,299AUD · price may vary

Model: BT-300US
Specifications: 0

Overview

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.

User Guide

What these specifications mean

Detailed specifications for iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah have not been published yet. iTechworld lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid and communication protocol (CAN or RS485) for talking to the inverter. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

What to check before ordering

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.
Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.

What people get wrong

Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.

Price and availability in Australia

iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah is listed at A$ 2,299 (AUD) for Australia. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Australia: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports iTechworld locally before ordering.

iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah — frequently asked questions

How much does iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah cost?

iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah is listed at A$ 2,299 (AUD) for Australia. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah?

iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah is a iTechworld product, listed under batteries with model reference BT-300US. The iTechworld brand page lists the rest of its range so you can compare across the catalogue.

Is iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah right for my system?

That depends on what it has to connect to. For a battery, check system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 against the rest of your equipment before price enters the decision. Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.

Where can I buy iTECH300US | Ultra Slim Deep Cycle Lithium Battery | with Bluetooth LiFePO4 300Ah in Australia?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Australia — buying in-channel is what keeps the manufacturer's warranty valid.
