48V 200AH Solar Storage Lithium Batteries Powering Homes At Night And On Cloudy Days

12V Solar Storage Lithium Battery and Eco-friendly Energy Solution for Solar Power Systems

12V sheet metal cased lithium batteries are a common and widely used type of battery, playing a crucial role in numerous fields.

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:

Performance Characteristics

Long Life: The cycle life of lithium batteries is usually much longer than that of lead-acid batteries. Under normal working conditions, the charge/discharge cycle times are far more than 500 times, and the service life can reach about 5 years or even longer, reducing the frequency and cost of battery replacement.

      Fast Charging: It supports fast charging technology and can be fully charged in a relatively short time, saving a lot of charging time and facilitating users to use the device frequently. For example, some 12V lithium batteries can charge from 0 to 80% in 1 - 2 hours using a dedicated fast charger.

      Low Self-Discharge Rate: Generally, it can be less than 1% per month, less than 1/20 of that of nickel-metal hydride batteries. This enables the battery to maintain a high power reserve even when not in use for a long time, reducing the trouble of frequent charging. The self-discharge rate comparison of common 12V batteries

Application Scenarios

1. 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.

2. Automotive Field: It can be used as the auxiliary power supply for hybrid and pure electric vehicles, powering the vehicle's electronic devices such as the audio system and in - vehicle computer. It can also be used as a starting battery. Compared with traditional lead - acid starting batteries, it has the advantages of light weight and long life.

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.
