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.
