120mΩ Solar Storage Lithium Battery Eco Friendly Support Bluetooth Solar Lithium Battery
12V metal-cased lithium batteries have become a widely adopted power solution across multiple industries due to their superior performance characteristics and reliability. These batteries typically offer a significantly longer lifespan compared to traditional lead-acid batteries, capable of enduring over 500 full charge/discharge cycles while maintaining optimal performance for approximately five years or more under normal operating conditions. This extended service life translates to reduced replacement frequency and lower long-term ownership costs.
One of the most notable advantages is their fast-charging capability, with many models able to reach 80% charge within just 1-2 hours when using compatible charging equipment. This feature dramatically reduces downtime and improves operational efficiency. Additionally, these batteries exhibit an exceptionally low self-discharge rate of less than 1% per month - a fraction of what nickel-metal hydride batteries experience - allowing them to retain nearly full charge during extended storage periods without requiring frequent maintenance charging.
In industrial applications, these robust batteries serve as reliable power sources for automated equipment, robotic systems, and various industrial tools, where their stable voltage output and durability are particularly valuable. The automotive sector also benefits greatly from this technology, where the batteries function as efficient auxiliary power units for electric and hybrid vehicles, powering onboard electronics while offering substantial weight savings and longer service life compared to conventional lead-acid batteries. Their rugged metal casing provides enhanced protection and makes them suitable for demanding environments across both stationary and mobile applications.
Structure and Principle
Usually, it is composed of 3 or 4 lithium batteries with a voltage of 3.7V connected in series to reach the rated voltage of 12V. In addition, it also includes components such as a protection board and a sheet metal casing. The protection board can automatically cut off the power supply when the battery encounters situations such as overload, overcurrent, overcharging, and overheating, playing a role in protecting the battery. The sheet metal casing provides mechanical protection for the battery, preventing the internal battery cells from being damaged by collisions, extrusions, etc. The specific parameters of a 12V 200Ah lithium iron phosphate energy storage power battery are as follows in the table:

Precautions
- Outdoor Camping: It can provide stable power for lighting equipment such as camping lights and flashlights, and also supply power for small electrical appliances such as portable fans, car refrigerators, and outdoor speakers. It can also charge electronic devices such as mobile phones, tablets, and cameras through an inverter, meeting outdoor entertainment and living needs.
- Industrial Equipment: Some industrial equipment such as automated equipment, robots, and power tools also use 12V sheet metal cased lithium batteries to provide power and control power, meeting various needs in industrial production.
- Emergency Backup Power Supply: In homes, offices, or commercial places, etc., it can be used as the backup battery of a UPS (Uninterruptible Power Supply). When the mains power is interrupted, it provides emergency power support for key devices such as computers, routers, and monitoring equipment, ensuring the normal operation of the devices and avoiding data loss or business interruption.
It is believed that driven by technological research and development, market demand, and environmental protection requirements, 12V sheet metal cased lithium batteries will embrace a broader development prospect, bringing more convenience and sustainability to our lives and work.
