Lead-acid batteries are still used in many electronic systems. However, in addition to the common problems of memory effect, poor power storage efficiency, large temperature influence, large size, heavy weight, and short life, lead-acid batteries also have serious pollution problems. This has led to more and more engineers wanting to replace lead-acid batteries with lithium batteries.

　　Since the voltage platform and performance of lithium iron phosphate batteries can perfectly replace lead-acid batteries, can lithium iron phosphate batteries directly replace lead-acid batteries on different occasions?

　　Due to the different characteristics of lithium batteries and lead-acid batteries, different charging and discharging curves and circuits, it is almost impossible to directly replace lead-acid batteries with lithium batteries.

　　The more difficult point is that the specifications of lead-acid batteries are 12V voltage, and the capacity ranges from 7AH to 70AH. The demand for electronic systems ranges from 100AH to 500AH or higher. Lead-acid batteries are stacked in series and parallel as required.

　　Lithium battery packs have a protection board BMS that controls overcharge and over-discharge. If they are directly connected in series or parallel in the manner of lead-acid batteries, protection performance conflicts or communication conflicts between the BMS of each battery pack will occur, which will result in abnormal use.

　　Lithium batteries replace lead-acid batteries, this behavior is not as simple as most people imagine. Because the electronic system needs to modify the charging and discharging circuit, a suitable lithium battery pack is also needed.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
