Voltage and capacity of lithium iron phosphate battery

　　1. Voltage of lithium iron phosphate battery

　　The nominal voltage of the single lithium iron phosphate battery is 3.2V, the charging voltage is 3.6V, and the discharge cut-off voltage is 2.0V. The lithium iron phosphate battery pack achieves the voltage required by the equipment through the series combination of electric cells. The battery pack voltage=N * the number of series connection. Common lithium iron phosphate battery pack voltages are as follows:

　　12V lithium iron phosphate battery

　　24V lithium iron phosphate battery

　　36V lithium iron phosphate battery

　　48V lithium iron phosphate battery

　　2. Capacity of lithium iron phosphate battery

　　The capacity of lithium iron phosphate battery pack is determined according to the capacity and number of cells in parallel, generally according to the specific requirements of electrical equipment. The more lithium iron phosphate cells in parallel, the greater the capacity. Common lithium iron phosphate battery packs have capacities of 10ah, 20ah, 40ah, 50ah, 100ah, 200ah, 400ah, etc.

　　Use of lithium iron phosphate battery at room temperature

　　Low current charging and discharging

　　In this field, if lithium iron phosphate battery is used normally, its cycle life is basically more than 2000 times; Small lithium battery manufacturers with lower quality also have a cycle life of more than 1000 times;

　　High rate and stable charging and discharging

　　The application of high rate discharge is mostly power type lithium batteries, and most of them are used to provide power for motors. Since most lithium iron phosphate batteries operate under high load, the decay time of battery materials is accelerated, and the cycle life is about 800 times.

　　High rate unstable charging and discharging

　　In this case, the service life of lithium iron phosphate battery will be shorter, only about 300 times.
