This Solarmax 12.8V 100Ah Lithium Battery functions as an energy storage unit. It acts like a large rechargeable power bank to store electricity generated from solar panels or the main grid, and releases it whenever you experience blackouts or are off-grid.
Because it uses Lithium Iron Phosphate (LiFePO4) chemistry, it is much more durable, efficient, and lightweight compared to traditional lead-acid or gel batteries.
