🔋 Product Description

The Sunwoda SMI-48100A1F6 is a high-quality 48V 100Ah rack-mounted LiFePO4 battery module, ideal for off-grid solar, telecom, and industrial backup systems. These batteries have been professionally dismantled from pre-assembled all-in-one units that were never commissioned or put into service. As a result, they’re in like-new condition, offering exceptional value at a fraction of the price of brand-new batteries.

Built with LiFePO4 (LFP) cells, each module provides 4.8kWh of reliable energy storage with over 4,000 cycles at 80% DoD and a design life of 10+ years. The compact 3U rack-mount design makes it perfect for battery cabinets and scalable energy storage applications, supporting up to 16 modules in parallel.

Each unit comes equipped with a built-in basic BMS that provides essential protections (over-voltage, under-voltage, over-current, temperature) and passive cell balancing. RS485 and RS232 communication ports offer integration with compatible inverters and monitoring systems.
