iTECH120X 120AH 12 Volt Lithium Water Proof Battery.


iTechworld has led the industry with our revolutionary iTECH120 lithium battery for over four years. 

Our iTECH120 lithium battery permanently changed the RV and camping market. Old and heavy lead-acid and AGM batteries, once the only option for battery storage, have now been pushed to the fringes.

iTechworld innovation has brought lithium battery storage from the elite to the mainstream. Now anyone can enjoy the vast benefits of high-quality lithium batteries without breaking the bank.

With the launch of our latest product, the iTECH120X lithium battery, we have yet again pushed the boundaries of what is possible with lithium battery technology.

The iTECH120X is the culmination of years of design and product development done right here in Perth, Western Australia. Our engineers have spent countless hours building and testing what we believe to be the highest quality lithium battery available on the RV market today.


One of the most common requests from our customers is the ability to connect more batteries in parallel to increase their power storage capacity. Our previous generation iTECH120 batteries had a limit of four batteries in parallel. While four batteries provided an excellent storage option for most customers, our engineers have innovated once again, and our new technology allows an unlimited number of new iTECH120X to be connected in parallel. There is now no limit on the size of your battery bank.

The latest Redback™️ Lithium Operating System has also been specifically programmed to allow series connection of our batteries for 24V applications.

The new 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. Perfect for those who prefer to travel off the beaten track.

Utilizing our latest prismatic cell design and newly developed vibration dampening technology, the iTECH120X is the toughest battery iTechworld has ever built. This means it will easily withstand the harshest Australian environments and provide many years of reliable service. 

As testament to the toughness and performance of the iTECH120X, we have backed it up with a full 3-year (36 month) replacement warranty.

In order to super-charge the iTECH120X’s performance, we have equipped it with the latest Redback™️ BMS (battery management system). The new BMS has been specially programmed by iTechworld engineers to squeeze every ounce of performance from the iTECH120X. This results in increased usable storage space, giving you more power to use while off-grid.

Another benefit of our new prismatic cell design is its inherent ability to maintain a balanced voltage across all cells. This ability, coupled with the auto-balancing algorithm on the new Redback™️ BMS will protect the battery from becoming unbalanced and shortening the lifespan of the battery.

Weight is now a constant concern for the caravanning and camping community. With strict laws regarding vehicle and caravan GVM and GCM, you do not want to exceed the legal weight limits and risk a big fine, or voided insurance. 

To help address the heavy weight common with traditional battery storage, the iTECH120X is now lighter than ever before. At just 12kg, it weights under 1/3rd the weight of an equivalent AGM or Lead Acid battery, which usually weighs more than 30-35kg each. 

With the iTECH120X, you not only save weight; you also increase usable power capacity. Lead Acid and AGM batteries can only use 50% of their available power before damaging the battery. For example, a 100AH AGM battery will give you 50AH of usable power before it needs to be recharged. The iTECH120X lithium battery provides over 100AH of usable power before it requires a recharge. That is double the usable power for 1/3rd of the weight!

Our new design has allowed us to increase the power storage capacity of the battery. Now with 107AH of usable power, the iTECH120X is our highest capacity battery to date.

Pushing the envelope is the iTechworld way. To continue this tradition with the iTECH120X, our engineers have increased peak power output to a peak draw of 380 amps with a sustained output of 175 amps for 5 minutes, and 150 amps continuously. Of course, the new iTECH120X retains all the standout features of our previous-generation batteries, including low self-discharge, under-voltage protection and thermal protection.
