Description
The EcoFlow Power Kits Battery 51.2 V 105 Ah 5120 Wh is a modular, high-capacity lithium-iron-phosphate (LiFePO₄) storage unit from EcoFlow, built for both reliable home energy backup and integration with solar systems. With a nominal capacity of approximately 5.12 kWh, the unit connects at a 51.2 V system voltage and supports stacking up to three identical modules to reach 10 kWh or 15 kWh capacity. The built-in battery management system (BMS) monitors and regulates performance, enabling safe charging and discharging across a wide temperature range (from as low as –20 °C up to +50 °C), and features hot-swap capability for minimal downtime. Its rugged design and IP54 protection grade make it suitable for semi-protected installations, and the LiFePO₄ chemistry ensures enhanced safety, stability and long cycle life compared with conventional lithium-ion cells.
