"Clean energy will improve our lives and we hope to make more people aware of this and recognise the change by using our products."

With this vision in mind, BSLBATT was founded in 2003. The goal of the BSLBATT team is to research and manufacture high quality and cost effective batteries and to design the most efficient and rational renewable energy battery systems. In line with the team's philosophy, BSLBATT strives to make its products as durable and economical as possible, so that even remote areas without access to the utility grid can enjoy the benefits of renewable energy.

Proven system design ensures that industrial and commercial energy storage systems pay for themselves within a few years, but in addition to technical excellence, an agile company structure is one of the secrets to success. In an ever-changing market, innovation, flexibility and speed are crucial. At BSLATT, flexible management, ready communication and the freedom to learn have become the order of the day, and the team serves the company's philosophy and future markets with confidence.

Whether yesterday, today or tomorrow, BSLBATT is still progressing and proudly delivering products worldwide.



BSLBATT specialises in battery storage systems for industrial and commercial use. 

The core module uses lithium iron phosphate (LiFePO4) battery modules, which can provide energy storage systems for large facilities such as data centres, microgrids, large scale battery storage, grid scale energy storage while maintaining safety. 

The lithium-ion battery-based storage system can operate at both high and low voltages and can be connected to grid-connected and off-grid sources, including wind, solar, biogas, hydroelectric and cogeneration. 

All BSLATT battery systems are manufactured in our own factory to achieve an annual production capacity of 1GWh.
