iTECH120X Product Details

Quick facts about the iTECH120X:

  • True drop-in replacement - no need to change chargers or equipment
  • Rated for under-bonnet use
  • IP67 Waterproof - perfect for external mounting
  • Only weighs 10kg (Equivalent AGM weighs approx. 60kg)
  • 100% usable capacity
  • 5 year Australian warranty
  • Australian designed and developed
  • Australian certified including IEC:62619

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.  

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.

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.

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. No other lithium batteries can match that in Australia today.

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.

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.

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.

What is the difference between the iTECH120X and iTECH100?

The iTECH120X is a superior battery to the iTECH100 for the following reasons:

  • iTECH120X has prismatic battery cells
  • iTECH120X has a larger discharge current
  • iTECH120X is waterproof to IP67 rating
  • iTECH120X has a longer lifespan
  • iTECH120X has more usable power
  • iTECH120X has a smaller footprint

Why is the iTECH120X the best lithium battery for caravan and camping?

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.

The iTECH120X is now lighter than before. Just 10kg, under 1/3 the weight of an equivalent AGM or Lead Acid battery, which usually weighs more than 30kg each.

With the iTECH120X, you not only save weight; but you also increase useable power capacity. AGM and lead acid batteries can only use 50% of their available power before damaging the battery. For example, a 100AH AGM battery will give you 50AH of power before it needs to be recharged. That is double the power for 1/3rd of the weight!

Our new design has allowed us to increase the power storage capacity up to 105Ah of power.

Peak power output to a peak draw of 270 amps with a sustained output of 175 amps for 5 minutes, and 150 amps continuously. Still with low self-discharge, under-voltage protection and thermal protection.
