CR1220 battery processing PACK manufacturer
From civilian digital and telecommunications products to industrial equipment, military power supplies, lithium digital batteries are widely used and used in batches, so for products with different voltages and capacities, lithium-ion batteries are usually used in series and parallel. The dedicated battery formed by the protection circuit, casing and output is called PACK. PACK can be a single battery, such as mobile phone battery, digital camera battery, MP3, MP4 battery, etc., or it can be a series-parallel combination battery, such as laptop battery, medical equipment battery, communication power supply, electric vehicle battery and backup power supply.
1. Configuration of CR1220 battery pack:
PACK includes battery pack, protective board, external packaging or casing, output (including connectors), key switch, power indicator light and auxiliary materials such as EVA, green paper and plastic bracket. The external characteristics of the PACK are determined by the application. There are several types of PACK.
2. Production process of CR1220 battery pack:

3. Functions of CR1220 battery pack
It has complete functions and can be applied directly.
Various species. Several packages are available to achieve the same application requirements.
Battery packs require a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).
The life of a battery pack is shorter than that of a single battery.
Used under limited conditions (charging, discharging current, charging method, temperature, humidity conditions, vibration conditions, stress levels, etc.)
CR1220 battery pack PACK protection board requires charge balance.
High voltage, high current battery packs (e.g., electric vehicle batteries, energy storage systems) require communication buses such as battery management systems (BMS), CAN, and RS485.
Battery pack PACK has higher requirements for the charger, and certain requirements are required to communicate with the BMS. The purpose is to ensure that each battery makes full use of the energy stored in the battery to operate normally, and that the battery is safe and reliable.
4.CR1220 battery pack design
Fully understand the application requirements (temperature, humidity, vibration, salt spray, etc.), usage time, charging and discharging methods, and usage requirements, such as electrical parameters, output method, life requirements, etc.
Choose qualified batteries and protective circuit boards according to usage requirements.
Meets size and weight requirements.
Packaging is reliable and meets your requirements.
The production process is simple.
Optimization.
Minimize your costs.
Detection is easy to achieve.
5. Precautions when using lithium batteries!
Do not put it in a fire or use it near a heat source!
Do not connect the positive and negative terminals of the output directly to metal.
Do not use it outside the battery temperature range.
Do not hold the battery with force.
Use a dedicated charger or charge in the correct way.
If the battery is in standby mode, please charge it every three months. Store at storage temperature.
