Rolls Surrette R48-105LFP 105Ah Lithium Battery

Rolls Surrette R48-105LFP 51.2V 105Ah Lithium Iron Phosphate Battery

The Rolls Surrette R48-105LFP is a high-capacity 51.2V 105 Ah (5.38 kWh) Lithium Iron Phosphate (LiFePO4) battery engineered for 48V off-grid solar energy systems, residential energy storage, and industrial DC backup. Designed as a consolidated single-unit 51.2V power solution, this battery eliminates complex multi-battery series strings while providing maintenance-free operation across deep discharge cycles.

Equipped with a heavy-duty internal 16S200A hardware Battery Management System (BMS), the IP65 weather-rated enclosure provides comprehensive protection against short circuits, over-voltage, low-voltage, over-current, and temperature extremes.
