1. Large capacity. The monomer can be made into 5Ah~1000Ah (1Ah=1000mAh), while the 2V monomer of lead-acid battery is usually 100Ah~150Ah, and the variation range is small.

2. Light weight. The volume of the lithium iron phosphate battery with the same capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the latter.

3. Strong fast charging capability. The starting current of lithium iron phosphate battery can reach 2C, realizing high-rate charging; the current requirement of lead-acid battery is generally between 0.1C~0.2C, which cannot achieve fast charging performance.

4. Environmental protection. Lead-acid batteries contain a large amount of heavy metal-lead, which produces waste liquid, while lithium iron phosphate batteries do not contain any heavy metals, and there is no pollution in production and use.

5. High cost performance.
