The lithium battery 12v 200ah is the technologically most advanced and feature-rich battery bank full of options. It works as a battery storage container for the solar system so that you can draw power when required. People often think that lithium-ion is more expensive than an AGM battery, which isn’t true. An AGM battery has a maximum of half of the discharge rate, which means you would require a double amount of ampere-hours to meet your power requirements. Further, the AGM batteries are heavier and need more connectors, accessories, and space. Lithium-ion batteries are lightweight due to their high energy density.
