25.6V 30Ah LiFePO4 Battery for Sonar Equipment

This 25.6V 30Ah low-temperature lithium iron phosphate (LiFePO4) battery is specifically designed for sonar equipment operating in extreme cold marine and polar environments. Utilizing high-performance low-temperature LiFePO4 cells and an optimized internal structure, the battery ensures stable discharge performance at temperatures as low as -40℃, maintaining reliable power output for underwater detection systems. The battery adopts a 8S2P configuration with a nominal voltage of 25.6V and a nominal capacity of 30Ah, delivering high energy density and long cycle life. Integrated intelligent BMS provides comprehensive protection functions, ensuring safe and stable operation in harsh offshore environments. With a robust and corrosion-resistant housing, this battery pack is suitable for long-duration underwater sonar detection, marine survey systems, unmanned surface vessels (USVs), and polar scientific research equipment.
