BSL ECO 5.12kWh 51.2V 100Ah LiFePO₄ Battery

The BSL ECO 5.12kWh Battery (B-LFP48-100E 3U) is a premium energy storage solution that combines safety, durability, and scalability. Using advanced LiFePO₄ chemistry, it delivers more than 6,000 cycles at 25 °C, ensuring a long service life with minimal capacity loss. At 90% depth of discharge, you get approximately 4.61kWh of usable energy per module, making it ideal for daily use in solar and backup applications.

Its powerful built-in battery management system (BMS) supports 100A continuous discharge, with peaks up to 120A for one second, giving it the ability to handle surges from appliances and machinery. Charging is equally versatile, with support for up to 100A continuous input and 150A peak for fast recovery.

This battery is designed to grow with your energy needs. You can parallel up to 63 identical units, reaching a total capacity of 322.56kWh. Its 3U rack-mount format keeps installations tidy, while communication options like RS232, RS485, and CAN ensure seamless integration with modern hybrid and off-grid inverters. Optional Wi-Fi and Bluetooth modules allow for convenient remote monitoring.

Safety is a core feature of the ECO series. The battery meets UN38.3 certification, is built to UL standards, and includes short-circuit and over-current protections for peace of mind.
