The iTECH300SS Super Slim battery is a small but powerful workhorse! At just 126mm wide, thIS 300Ah lithium battery was specifically developed for those seeking maximum power in a small package. Designed and developed in Australia, for Australia, the iTECH300SS has been constructed to thrive in the Australian climate and conditions.
This lithium powerhouse uses A-grade prismatic LiFePO4 cells, which offer significant advantages over other cell types — they’re thinner, lighter, longer-lasting, and more space-efficient. Our 300Ah lithium battery is 100% usable, delivering an impressive amount of power in a slim profile. Despite its size, the iTECH300SS can confidently support high-demand setups, including systems running 3000W inverters.
Never second-guess your battery’s health again! The 300 amp lithium battery from iTechworld is integrated with full Bluetooth compatibility, allowing you to monitor your battery’s status in real-time via the iTechworld Connect Battery Management app. Not only can you check your battery’s vitals in real-time, but you can also rest easy knowing your battery is Australian-certified to IEC:62619 standards.

The iTECH300SS is designed to deliver 100% usable 300Ah capacity, making it suitable for high-demand setups, including systems running 3000W inverters.
The battery’s built-in BMS (Battery Management System) further extends its tolerance with an operating envelope from –40°C ~ 80°C, helping protect the battery during extreme ambient temperature swings.
When pairing a 300Ah lithium battery with a 3000W inverter, the key factor is ensuring that the inverter’s voltage and current requirements fall within the battery’s capabilities.
The iTECH300SS supports series connections up to 48V (meaning up to four batteries in series) and unlimited parallel connections.
The stated cycle ratings indicate that using your 300Ah lithium battery at its maximum discharge rate will reduce the cycle life of the battery.
That construction makes it suitable for rugged environments, including coastal or moisture-prone settings where corrosion is a concern.
It is recommended to isolate the battery completely, charge it to 13.5V and check the voltage every 3 months, then charge the battery as needed.
Its continuous discharge rating is 200A, but it can deliver a peak of 640A for short bursts (up to 5 seconds). That capability makes it well-suited for powering compressors, heavy-duty inverters, or other start-up loads.
iTechworld recommends a solar-to-battery ratio of at least 2:1.
You can safely install your 300Ah lithium battery vertically or horizontally, but under no circumstances should it be installed upside-down.

Traditional AGM batteries are heavy. One AGM battery can weigh a back-breaking 30+kg. An iTECH120X almost defies physics as it weighs up to third less than conventional AGM batteries but has much more power available.
AGM or lithium? There was only one choice back in the good old days: lead-acid AGM; then along came iTechworld lithium batteries, and everything changed.
Inside each iTechworld battery is a Battery Management System that has several different safety features that you will not find in lead acid, calcium or even other lithium batteries. To ensure iTechworld batteries are the safest batteries availabl...
