Product Description
Lithium iron phosphate battery is a kind of lithium ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. It has the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.
Pustun lithium iron phosphate battery is your best power choice for energy storage system of solar street light. This LFP series battery is specifically designed for solar street light application, which has more than 10 years service life; LFP series batteries are the best choice for the durable, safe, environment-friendly energy solution and they can be customized according to your requirement, such as dimension, voltage, capacity of battery. With an increased lifespan, this battery can save you much cost against frequent battery replacement. The working life of lithium battery especially under the outdoor high temperature environment is five times longer than the traditional lead acid battery.
