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

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.
