Main features for 7.4V 18650 high discharge rate battery cells
1. It has high power bearing capacity. Among them, the lithium iron phosphate lithium ion battery used in electric cars can reach the capacity of 15-30c charging and discharging, which is convenient for high-intensity start-up and acceleration.
2. The self-discharge rate is very low, which is one of the most prominent advantages of the battery. At present, it can reach less than 1% per month, less than 1/20 of the nickel hydrogen battery.
