This 3.2V 1200mA lithium iron phosphate lithium ion battery is a combination of two batteries. Compared with lead-acid batteries, it has a good lifespan. Lead-acid batteries are generally 1-1.5 years; compared with nickel-hydrogen batteries, they have a higher working voltage; compared with nickel-cadmium batteries, they have a better environment Friendliness, this is also an important reason why lithium iron phosphate defeated these batteries and set off a lithium battery storm. Although ternary batteries are popular at this stage, due to the safety problems of ternary batteries that are difficult to control under high energy density, lithium iron phosphate The battery is still in large-scale application, but domestic battery companies are developing lithium iron phosphate batteries to a large scale, using high-capacity lithium iron phosphate batteries (100AH or even 200AH batteries).Q1.
