1. Lithium iron phosphate battery pack refers to a lithium-ion battery using lithium iron phosphate as a positive electrode material. Its characteristic is that it does not contain precious elements such as cobalt, the price of raw materials is low, and phosphorus and iron are abundant in the earth's resources, so there will be no problem of feeding. Its working voltage is moderate (3.2V), large capacity under unit weight (170mAh/g), high discharge power, fast charging, and long cycle life, high stability under high temperature and high heat environment.
2. Small size and lightweight. The volume of the lithium battery pack is 2/3 of the volume of the lead-acid battery. The weight is light, only 1/3～1/4 of the lead-acid battery.
The cycle of life is long. The cycle life of the lithium iron phosphate battery pack is 1200 to 2000 times, but the traditional lead-acid battery is only 500 to 900 times.

The charging and discharging characteristics are good. The conversion efficiency of the charge and discharge energy of the lithium battery pack can be greater than 97%. The conversion efficiency of the charge and discharge energy of the lead-acid battery is about 80%.
Safety and environmental protection, lithium iron phosphate material does not contain any heavy metals and rare metals, non-toxic, no pollution in production and use, in line with European RoHS regulations, is a green environmental protection battery lithium battery. In experiments such as puncture, squeeze, overcharge, and short circuit, there is no explosion or fire.
No memory effect, the battery can be charged and discharged at any time.
The operating temperature range is wide, and the peak heat of the lithium iron phosphate battery pack can reach 350℃-500℃, while the lead-acid battery is only around 200℃.
