The iTECH120X lithium battery has over 10 years of design and development in Australia. Our Australian engineers have spent countless hours building and testing what we believe to be the highest-quality lithium battery available on the market today.
Our technology now allows an unlimited number of new iTECH120X to be connected in parallel. You can make a battery any size you wish by connecting as many iTECH120X lithium batteries together to make a 12v MEGA battery of any size. The latest operating system allows a series connection of 4 lithium batteries for 48V applications.
Never guess your batteries health again. The iTECH120X 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. Google Play app coming soon.
iTechworld has been designing and developing Lithium Batteries for over 10 years, constantly improving and testing our designs. The iTechworld Lithium Batteries are Australian standard certified to IEC:62619 to create the safest and highest-quality lithium batteries available in the Australian market.
No changing of systems, equipment, or extensive re-wiring is required in most cases. You simply pull your old heavy AGM batteries out and put the new lightweight iTECH120X in. The iTECH120X is the only true drop-in upgrade for your existing batteries.
Utilising our latest prismatic cell design offering more vibration resistance and stability for big bumps with vibration-dampening technology, the iTECH120X is the toughest deep cycle battery iTechworld has ever built.
The iTECH120X is entirely water and dust sealed. Boasting an IP67 rating, this battery can be fully submerged in 1m deep water for up to 30 minutes and has the highest level of dust protection available. No other lithium batteries can match that in Australia today.
In order to super-charge the iTECH120X’s performance, we have equipped it with a new Battery Management System (BMS) specially programmed by iTechworld engineers to auto cell-balance and squeeze every ounce of performance from this deep cycle battery.
As a testament to the toughness and performance of our iTECH120X lithium batteries, we have backed them up with a full 5-year Australian warranty (3 years full replacement, 2 years pro-rata).

The iTECHDCDC25 keeps your battery charged no matter the battery type or size.
The all-new iTECHDCDC25 charger incorporates an MPPT solar controller allowing charge from solar panels or blankets. When the vehicle runs, the DCDC charger will charge via the alternator; when the vehicle stops, the iTECHDCDC25 will continue charging via your solar panels/blankets (if added).
Exclusive to iTechworld DCDC chargers is a function known as Solar Power Priority (SPP) which represents the preference for solar input. This allows you to set your iTECHDCDC25 to use solar input over the vehicle alternator's input at the push of a button. Solar Power Priority places less load on the alternator, is better for the environment and helps to reduce fuel consumption.
Designed and developed in Australia for Australia, the iTECHDCDC25 is IP67 Waterproof, Dustproof and vibration-proof. Built with a heavy-duty metal case uniquely designed to help with heat dispersion, the iTECHDCDC25 is suited and warranted for under-bonnet installation. Mounting brackets are included in the case design, allowing for easy installation in your setup.
Many vehicles now have smart alternators that do not produce a high enough voltage to charge auxiliary batteries; the iTECHDCDC25 works by enhancing the voltage to the auxiliary battery regardless of the alternator type; the enhancement of voltage is also valuable for overcoming voltage drop from long cable runs to caravans and camper trailers.
A unique feature of the new iTECHDCDC25 is the ability to accept a wide voltage input range from either solar or vehicle input, with the maximum input voltage now being 32v. As the iTECHDCDC25 accepts higher input voltages, it opens the door to 24v inputs as well as some larger voltage solar panels commonly found in residential installations.
The new iTECHDCDC25 is compatible with all battery types but comes into its own when paired with iTechworld lithium batteries. All iTechworld lithium batteries have low voltage protection and will enter "safe mode" to protect themselves when their voltage dips below 10v.
There are various methods to bring an iTechworld lithium battery out of safe mode, but the new iTECHDCDC25 will get an iTechworld lithium battery out of safe mode automatically; if the lithium battery enters safe mode, turn off any load on the battery and the iTECHDCDC25 will take care of the rest, it's that simple.
