AST-320 12.8V 320A 4096Wh Lithium Battery Removable Series Connectable
The AST-320 is a 12.8V – 320Ah lithium battery designed to offer high performance, reliability, and safety in advanced energy applications such as photovoltaic systems, RVs, and boats.
Made with advanced technology and high-quality components, it ensures intelligent energy management and long life.
Each cell has an individual QR code that, when scanned, allows you to find information about the cell on the website.
The assembly method involves positioning the cells with an aluminum alloy fixing plate, followed by securing the entire cell group with stainless steel clamps.
The AST battery with red cap can be connected in series, up to four units. Series connection allows for a system voltage of 24 V, 36 V, or 48 V.
Longer than traditional lithium batteries, with up to 6,000 charge and discharge cycles, while other types of lithium batteries (such as lithium-cobalt batteries) typically last 500 to 1,000 cycles.
