BMS 12V 7Ah Quality Lithium Battery For Long Cycle Life

Generally speaking, batteries are categorized as primary batteries (using them as power sources for electric vehicles is a thing of the past), secondary batteries, and fuel cells. Automotive batteries are classified by electrolyte properties into acidic and alkaline, by form factor into square and cylindrical, by usage into mobile and stationary, by application into power, starting, and standard, and by structure into open and sealed. Lead-acid batteries come in various forms, such as tall and short. They are classified by the acidic electrolyte into rich, lean, and gel electrolyte types, and by plate structure into plate, spiral, and tubular.

Currently, conventional batteries for electric vehicles primarily include lead-acid, nickel-metal hydride, and nickel-zinc batteries. Lead-acid batteries are the most popular, while the other two remain relatively rare. This is primarily due to the lack of market development and the lack of large-scale production suitable for electric vehicles, resulting in prices that are not yet affordable to the general public. However, this trend will soon become popular. The other three technologically successful batteries - lithium-ion batteries and zinc-air batteries - are upgraded products after nickel-metal hydride and nickel-zinc batteries; the price of fuel cells is still out of reach, mainly because the cost of preparing proton exchange membranes is high, catalytic metals are precious, and some technologies still need to be improved. They have not yet entered the production field on a large scale and it will take another 6 to 8 years for them to become popular.

Solar energy system products require professional technicians to install. For safety reasons, we do not recommend that customers install solar products themselves unless they are professional technicians.

We can provide technical support during the installation process. If you have any questions, please send us the relevant photos and videos for communication and check. We will provide online technical services in time.
