Overview

Introducing our all new and improved iTECH400X PRO lithium deep cycle battery with Bluetooth. As one of the most powerful 400Ah lithium batteries in Australia, the iTECH400X PRO was designed with the country’s harsh climate in mind which is why this iTECH400X PRO is IP67 waterproof, suitable for high heat conditions, vibration proof, certified to IEC:62619 and backed by a 5-year Aussie warranty.

Thanks to our extremely high-quality patent pending A-grade prismatic lithium LiFePO4 cells, we have been able to shrink the size of the 400Ah lithium battery to the same size as many standard AGM 200Ah battery packs while having the equivalent useable power as four (4) of them combined. The iTECH400X PRO features a fully 100% usable capacity, allowing the full 400Ah (Amp Hours) to be drawn from the battery.

Never guess your batteries' health again. Our 400Ah lithium battery now comes with integrated with Bluetooth compatibility to monitor your batteries status via the iTechworld app. Download the iTechworld app on the App Store or Google Play Store.

For almost 20 years iTechworld has been at the forefront of Australian lithium battery design and development. Our relentless pursuit of improvement and rigorous testing insures all our batteries surpass the highest standards. Certified to the Australian standard IEC:62619, iTechworld 400ah lithium batteries are amongst the safest and most reliable options in the Australian market.

With its compact design, the iTECH400X PRO is a true drop-in replacement for your existing system. No changing of systems, chargers, or equipment is required in most cases. Simply pull out your old AGM or flooded lead-acid battery and drop in the iTECH400X PRO. It's that easy!

The 400Ah lithium battery range includes an all-new patent-pending prismatic cell type, as well as an all-new supercharged Battery Management System (BMS) allowing for less cell degradation, safe and accurate operation, and a longer lifespan with high current use. With a maximum discharge current of 640A running high power appliances through a 3000W inverter such as air conditioners, coffee machines & any other creature comfort is a breeze.

The 400Ah lithium battery is waterproof and dustproof, boasting an IP67 rating. This Bluetooth lithium battery can be fully submerged in 1m deep water for up to 30 minutes and is perfect for external mounting on caravans, camper trailers and boats.

What these specifications mean

Detailed specifications for iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah 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 communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% and system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack. 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.

Choosing a battery: the checks that matter

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.

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.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Common mistakes

Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
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.

Price and availability in Australia

iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah is listed at A$ 2,499 (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.

iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah — frequently asked questions

How much does iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah cost?

iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah is listed at A$ 2,499 (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 iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah?

iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah is a iTechworld product, listed under batteries with model reference BT-400XPRO. The iTechworld brand page lists the rest of its range so you can compare across the catalogue.

Is iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah 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. 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.

Where can I buy iTECH400X PRO | Lithium Deep Cycle Battery | with Bluetooth LiFePO4 400Ah 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.
