Advantages and disadvantages of lead-acid batteries and LIfepo4 batter

Advantages and disadvantages of lead-acid batteries：

Advantages:  stable voltage, cheap price, simple maintenance, stable quality, and high reliability.

Disadvantages: low Energy Density, short service life, frequent daily maintenance.

Advantages and disadvantages of LifePO4 batteries：

Advantages: Lithium-ion batteries are highly adaptable to high and low temperatures, can be used in an environment of -20°C-60°C, and can be used in an environment of -45°C after technical treatment.
The lithium iron phosphate battery has a long life, and the cycle life is more than 4000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.
Safe to use. The lithium iron phosphate battery has undergone strict safety tests and will not explode even in a traffic accident.

Disadvantages:  With poor electrical conductivity, slow diffusion of lithium ions, and high times when charging and discharging, the actual specific capacity is low.
The poor low-temperature performance of lithium iron phosphate ion battery.

I： Long service life
The  Normal Use Cycles of lead-acid batteries are around 200 times, and the highest is 300 times the normal use cycles. Lithium iron phosphate ion batteries have Normal Use Cycles of more than 4000 times.

Second.：Safe

Lithium-ion batteries completely solve the safety hazard of lead-acid batteries. Lead-acid batteries can explode under strong collisions, posing a threat to consumers' lives. And lithium-ion batteries do not explode under strict safety tests.

Three： Size and Weight.

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

Fourth： Price

Lithium-ion batteries are more expensive than lead-acid batteries.
