48v 100ah Lithium (LiFePO4) Battery Backup System

Model: B-LFP48-100
Battery Type: LiFePO4/Lithium Battery
Number of Cells: 15 cells
Data-sheet: B-LFP48-100E

The B-LFP48-100 LiFePo4 battery is an expandable battery pack with a built-in BMS system, which can be combined into a rack storage system or used individually in a home solar system.  B-LFP48-100 is a smart residential energy storage device that enables homeowners to store the electricity generated by the on-site solar system or grid for use as an emergency home backup battery. Although it is attractive as an emergency power supply device, B-LFP48-100 was designed from the ground up to provide homeowners with on-site solar energy systems with a way to extend the electricity generated during the day to night, and is relative to Powerwall.

The worlds smallest battery management system

The built-in battery management system integrates with multilevel safety features including overcharge and deep discharge protection, voltage and temperature observation, over current protection, cell monitoring and balancing, and over-heat protection. This high-performance BSLBATT® Lithium Battery has a large power capacity, with a fast charging and continuous discharge power, providing 98% efficiency. The advanced Lithium Ferro Phosphate (LFP) technology operates a wider temperature range to deliver the most dependable performance. LFP has been proven to be one of the safest Lithium technologies in the industry and is manufactured to the highest standards.
