Bosa aims to become a leading LFP industrial battery supplier in China. Our core business focuses on lithium-ion batteries and integrated power systems, widely used in energy storage, electric vehicles, and marine applications.
With excellent quality and reliable performance, our products are trusted by customers in more than 30 countries worldwide. We also hold a number of patents that are actively applied in lithium battery research and development, supporting continuous innovation.
Our manufacturing capabilities are powered by four AI-driven production lines, covering the entire process from:
These advanced capabilities ensure high consistency, efficiency, and product reliability.

Thanks to these advantages, Bosa’s LiFePO4 batteries serve as an ideal replacement for traditional lead-acid batteries. From a long-term perspective—including savings in energy consumption, maintenance, labor, and reduced downtime—can significantly lower the total cost of ownership (TCO).
Our 51.2V electric boat battery pack:
It’s a modular design which means you can easily scale up your energy system. With this building block you can configure systems until 840Ah (max 8 in parallel) or 1000V (max 20 in series).
The unique combination of state-of-the art technology, an integrated BMS and smart software makes this lithium battery a robust, safe and easy to use energy storage solution.
