12V/24V LiFePO4 Battery
Lithium-ion batteries have revolutionised our lives since they first entered the market in 1991. They have laid the foundation of a wireless, energy fuel-free society, and are of the greatest benefit to humankind.

Lithium Battery had more advantages compared to lead acid battery in terms of the specific energy, specific power, cycle life and fast charging.
The substantial benefits that Lithium Ion technology offer over lead-acid technology means that using Lithium Ion batteries is becoming an ever more popular choice.

Compared with lead-acid batteries, lithium-ion batteries have the following advantages:

1. Lithium battery has higher energy density, lead-acid battery is 30WH/KG, and lithium battery is 110WH/KG.

2. The cycle life of lithium batteries is longer, the average lead-acid battery is 300-500 times, and the lithium battery is more than a thousand times.

3. Different nominal voltages: single lead-acid battery is 2.0V, single lithium battery is about 3.6V, lithium-ion battery is easier to connect in series and parallel, and different battery packs can be obtained for different projects.

4. Under the same capacity, the volume and weight of lithium batteries are smaller. Lithium batteries are 30% smaller and weigh only one-third to one-fifth of lead acid.

5. The current application of lithium ion is safer, and BMS manages all modules in a unified manner.

6. The price of lithium ion is more expensive, 5-6 times that of lead acid.

At present, in the field of household light storage and charging, the mainstream batteries are lithium-ion batteries and lead-acid batteries. However,In the early stage of energy storage development, due to the technology and cost of lithium-ion batteries, it was difficult to obtain large-scale applications.

At present, with the improvement of lithium-ion battery technology maturity, the reduction of large-scale manufacturing costs and good policy, the current lithium-ion battery has greatly surpassed the application of lead-acid batteries in the household field. Of course, product attributes also need to match the character of the market. In some markets with outstanding cost performance, the demand for lead-acid batteries is also strong.

The following is a comparison of the installed capacity of lithium-ion batteries and lead-acid batteries in the field of household optical storage and charging
