The iTECH300SS Super Slim battery is a small but powerful workhorse! At just 126mm wide, the iTECH300SS 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. The 300Ah capacity 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 iTECH300SS 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.
