12V batteries are batteries with a voltage of around 12V, mainly lead-acid batteries and lithium batteries (nominal 12.8V). 12V lithium batteries have outstanding advantages in terms of weight, lifespan, stability, and environmental protection. Replacing 12V lead-acid batteries has become an irreversible trend. The 12V lifepo4 battery can not only power solar street lights, emergency lighting, electric wheelchairs and other equipment, but can also power notebook computers, refrigerators, batteries and other equipment through an external sine wave inverter. It can also be used in camping, RV, cabin and other scenarios.
