Technological innovation: reliable hardware and artificial intelligence guarantee security

Reliable hardware: BSLBATT Battery uses a battery cell made of the most stable lithium-ion material, lithium iron phosphate. They will not catch fire or explode in a pinprick test. 51.2V 100AH lithium battery and 51.2V 200AH power wall batteries use battery module level fire extinguishers. In the event of overheating or thermal runaway, flames can be extinguished quickly and accurately, eliminating fire hazards within components.

AI: BSLBATT Battery adopts a three-layer battery management system (BMS) to achieve refined management. The AI intelligent algorithm predicts the internal short circuit of the battery cell and gives an early warning to protect the safety of the lithium-ion battery system. In addition, 51.2V 100AH lithium batteries and 51.2V 200AH power wall batteries support mixed use of new and old batteries, automatic group capacity detection, and autonomous management.

Safety certification: comprehensive verification from components to systems

51.2V 100AH lithium batteries and 51.2V 200AH power wall batteries have passed the safety certification of batteries, modules, and systems in accordance with IEC62619, UL1973, UN38.3, and GB standards. It is currently the household energy storage lithium-ion battery product with the most types of industry certifications and the most comprehensive tests. The UL1973 certification test evaluation further confirmed the safety and reliability of 51.2V 100AH lithium batteries and 51.2V 200AH power wall batteries.

With these features and powerful performance, 51.2V 100AH lithium battery and 51.2V 200AH power wall batteries will create greater value for customers and partners. Looking forward to the future, BSLBATT will increase investment in research and development, and jointly promote the development of the lithium-ion battery industry with customers, associations, and other industries, and help the sustainable development of clean energy.
