48V 6Ah Lithium Battery Solution for Electric Fire Extinguisher

Electric fire extinguisher
The traditional emergency fire pump were powered by lead-acid battery or diesel engine as the role emergency power of electric fire extinguisher, which has been unable to meet the modern portable emergency power supply due to the low energy density,overweight,low discharge rate and discharge efficiency, no friendly environment and other shortcomings, and the noise of diesel engine, no environmental protection. Due to the high energy ratio, light weight, small size, long cycle life, high safety, high discharge ratio, and other unique advantages, lithium battery has become the preferred alternative lead-acid and diesel engine in the field of emergency power supply. Which make the product lighter and more convenient for operation .
