Lithium Iron Phosphate Battery has higher energy efficiency, higher temperature tolerance and lower self-discharge properties. This makes it suitable for Emergency Lighting Products. Phosphate based technology has excellent chemical and thermal stability, which provides better safety property than lithium battery.
Lifepo4 cell is incombustible in event of mishandling, and can withstand high temperatures without decomposing. Phosphate chemistry supply long cycle life. Lifepo4 battery include PCM, which supply protection, control charge and discharge current, to improve reliability and performance maximum.
Lifepo4 battery has low self-discharge, it does not require constant charging. At commissioning stage, it is charged fully, then reach limit when the capacity is lower than a certain amount of water. This reduces the parasitic load and improves overall power consumption. About the battery projected life, Ni-Cad battery, Ni-Mh battery is replaced every four years, but lifepo4 battery pack can last in excess of eight years.
