12V lithium battery is connected in series with 3 or 4 lithium batteries. Combined battery pack, the capacity of the battery is determined according to the capacity of a single cell or the capacity of parallel batteries, which is a new type of safe and environmentally friendly battery. Let's take a look at the precautions for the use of 12V lithium batteries. What are the uses of 12V lithium battery?

Precautions for the use of 12V lithium battery:

1. Different 12V lithium battery brands, different batteries, different battery models are also different, and the chargers are naturally different and cannot be universal. If the chargers are often mixed, the charging voltage and current do not match, which will cause the battery to charge.
2. Stop charging when the charger turns green in summer, and float for 1-2 hours after the charger turns green in winter. Over 12 hours or more, the battery can be easily recharged.
3. When charging at high temperature, the charging voltage is relatively high, and the battery is easily overcharged, which will cause the battery to lose water and dry up prematurely during the charging process, which will seriously affect the service life of the battery. Research data shows that the battery life is shortened by 40% in an environment of 45°C.
4. When the 12V lithium battery is in use, the battery itself will heat up. If charged immediately after use, the battery will be exposed to high temperature for a long time and it is easy to charge the drum.

Use of 12V lithium battery:

The 12V lithium battery protection board is a battery protection circuit board, which is generally used for large-capacity 12V lithium batteries. With overcharge, over-discharge, over-current, short-circuit protection functions, battery balance function. Some batteries may also require communication ports and data input and output. options and other display features to suit application requirements.

12V lithium batteries are used in electric vehicles, inverters, mobile DVDs, UPS, GPS, medical equipment, etc., and the application fields of cathode materials are obviously differentiated. At present, lithium cobalt oxide is still the main cathode material in the field of small lithium batteries, mainly used in traditional 3C fields, etc.; ternary materials and lithium manganate are mainly used in small lithium batteries. Power battery technology is relatively mature, mainly used in power tools, electric bicycles and electric vehicles. Central energy storage, household energy storage, wind energy photovoltaic energy storage and other fields.
