LiFePO4 12V 40Ah Lithium Automotive Battery For Car Start

This lithium automotive battery series are based on lifepo4 technology. Compared with lead acid starter batteries, they have very high discharge rate with a smaller capacity and lighter weight.They also feature BMS inside for the safest and long-life performance. They have lower self-discharge rate so they can still provide enough cranking power when sitting for months.
