Lithium Battery Module Pylontech LV 3.55kWh FL4874M Force L2

Product Description

The Pylontech Lithium Battery Module LV 3.55kWh FL4874M Force L2 is the basic unit of the Force L2 low voltage system (48 V). It stacks directly on the base and under the BMS, without wiring between modules, which speeds up assembly and reduces errors. With LiFePO4 (LFP) chemistry, 90% depth of discharge and 96% efficiency, it ensures safe and stable energy for more than 6000 cycles, with IP55 protection rating and a residential aesthetic.

Main Features

• Capacity per module: 3.552 kWh (48 V, 74 Ah) with high-safety LFP cells.
• 2p15s architecture optimized for 48 V; stacking without cable bridges.
• 90% DoD and system efficiency ≈96% for more usable energy per cycle.
• Longevity: >6000 cycles and estimated service life of 15 years under nominal operation.
• IP55 protection and certifications VDE 2510-50, IEC 62619, and UN38.3.
• Compact format: 450×296×296 mm and 35.5 kg per module.

Advantages or Benefits

• True scalability: add FL4874M modules to increase capacity in the same tower.
• Quick installation: guided stacking without wiring between modules, fewer incidents.
• Safety and reliability: stable LFP chemistry and international certifications.
• High efficiency: more kWh available each day and lower cost per usable kWh.
• Simple integration: RS485/CAN communication via the FC0048M-100S BMS.

Purpose or Applications

Expansion of Force L2 systems in homes, small businesses, backup, hybrid on-grid self-consumption, and 48 V off-grid. Ideal when growth in stages is required with a clean and compact format.
