How to choose a high-quality 18650 lithium battery?

Choose the most suitable 18650 lithium battery according to our electrical equipment, such as the appropriate brand, voltage, capacity, continuous discharge rate, battery life, etc. The most important thing is to choose a battery with high safety. Below we will introduce them in detail:

  • Brand 

    As for brands, the most reliable ones are Sanyo, Samsung, SONY, LG and other internationally renowned brands.Sanyo and LG focus on routines, and their applications are mainly bright flashlights, power banks, laptop batteries, etc.SONY professional, the main power and high current. Taking VTC4 as an example, the discharge current can reach 30A, and it can easily handle electronic cigarettes, toys, etc.

  • Nominal capacity 

    The nominal capacity of the 18650 battery is related to the battery life. The unit is “mAh”. The higher the capacity, the stronger the battery life. For example, a 2800mAh battery can be continuously discharged for 2 hours at a current of 1.4A.

  • Continuous Discharge Current (CDR) 

    Continuous discharge capacity is expressed by C rate, continuous discharge current = continuous discharge capacity C number × capacity.For example, the capacity of a 18650 battery is 2800mAh and the continuous discharge capacity is 0.5C, then the continuous discharge current = 1.4A. If the discharge exceeds 1.4A for a long time, the battery life will be seriously affected, and there may be dangers of overheating, even burning, explosion, etc.

  • Resistance 

    The internal resistance is the resistance of the battery itself. The smaller the internal resistance, the lower the consumption and the stronger the discharge capacity. The parameter of internal resistance is generally written on the battery introduction page. You should also pay attention to it when purchasing. Try not to buy more than 100mΩ or more cells.If you use multiple 18650s in series, you must buy batteries of the same brand and type, otherwise, batteries with large internal resistance and low capacity will become a shortboard.

  • Temperature 

    Temperature is a major factor affecting the life of 18650 lithium batteries. The higher the temperature, the faster the battery will age, and the higher the temperature, the greater the damage to the battery.

FAQ:

  • What are the key components of 18650 battery packs?
    The key components are 18650 cells, PCM/BMS, structure(circuit design).
