What is the charging voltage range of lithium iron phosphate batteries

Generally, the upper limit voltage of lithium iron phosphate battery charge is 3.7~4V, and the lower limit voltage of discharge is 2~2.5V. Considering the five aspects of discharge capacity, median discharge voltage, charging time, constant current capacity percentage, and safety, constant current and constant voltage are adopted. For lithium iron phosphate batteries, it is reasonable to set the charging limit voltage at 3.55～3.70V, the recommended value is 3.60～3.65V, and the lower limit voltage of discharge is 2.2V～2.5V. The lithium iron phosphate battery has a design 3.6v charging limit, so that the design can fully activate the battery capacity to the maximum without damaging the battery. The number of charging refers to the number of full charge and discharge cycles. Although the design of 3.4V is not overcharged, a small part of it will not participate in the cycle charge and discharge, and most of the participants will increase to a certain number of cycles due to the number of cycles, and still have performance Deterioration, a vicious circle until it is unusable. This is the limitation of its life, the overlap of various unsuspecting harmful and unfavorable factors, and the inevitable performance cannot maintain the original design parameters. Although the lithium iron phosphate battery pack has a design-limited voltage, it is also equipped with a protection board to protect the lithium battery pack from overcharging. But if you want to make the life of the lithium battery pack longer, the correct charging method is also very important.
