The Itel 5kW lithium battery (typically 5.12 kWh, 51.2V 100Ah) is a LiFePO4 (Lithium Iron Phosphate) energy storage solution designed for solar, backup, and off-grid applications. It features a long cycle life (around 6,000 cycles at 80% DOD), a compact design (often rack-mountable or wall-mountable), and an intelligent Battery Management System (BMS) for safety and optimal performance. It's also scalable, allowing multiple units to be connected in parallel.
