The BSL Battery Stubby 51.2V 172Ah is a high-performance 8.8kWh Lithium Iron Phosphate (LiFePO4) storage solution designed for compact residential and commercial energy systems.
The BSL Battery Stubby (B-LFP48-170E) is an 8.8kWh lithium-ion battery engineered for exceptional reliability and efficiency. Utilizing Lithium Iron Phosphate (LiFePO4) technology, it provides a safe, non-toxic, and long-lasting alternative to traditional lead-acid batteries. Its unique "Stubby" form factor allows for installation in tighter spaces without sacrificing energy density, making it a favorite for both wall-mounted and shelf-mounted solar applications.
Equipped with a sophisticated internal Battery Management System (BMS), the unit actively monitors and protects against overcharge, over-discharge, short circuits, and thermal runaway. It supports seamless integration with leading hybrid inverters such as Victron, Sunsynk, Deye, and Growatt through robust communication protocols. With the ability to parallel up to 63 units, the system is highly scalable for growing energy demands.
